Understanding "Myalgic Encephalomyelitis" (also known as Enteroviral Encephalomyelitis) and how it's not the same as "Chronic Fatigue Syndrome" criteria's or the SEID "ME/CFS" algorithm, which reflect "missed diagnosed" Chronic Fatigue Syndromes. "M.E." is actually EXCLUDED.


Background
 

If a patient or a family member has tried to search the internet for an understanding of Epidemic Myalgic Encephalomyelitis (also known as Enterviral Encephalomyelitis) M.E.,...






...or so-called “Chronic Fatigue Syndrome” (CFS),...

...currently being called “ME/CFS”),...

...they will have been overwhelmed by the multitude of technical descriptions and the numerous overlapping medical conditions.





IOM committee proposes new name for "Chronic Fatigue Syndrome"

"After reviewing more than 9000 scientific studies, hearing testimony from experts, and soliciting input from the public, the committee concluded that "the name 'Chronic Fatigue Syndrome' has done a disservice to many patients," calling it  'stigmatizing and trivializing.' Myalgic encephalomyelitis (M.E.) (also known as Enteroviral Encephalomyelitis), they noted, 'does not accurately describe the major features of the disease.'"

They indicate here that 'ME/CFS' is a new term for 'Chronic Fatigue Syndrome' and is NOT to be confused with 'Myalgic Encephalomyelitis' (also known as Enteroviral Encephalomyelitis) as there is a 'lack of evidence' of 'Encephalomyelitis' and 'Myalgia' is not a core symptom. It also recommends that 'ME/CFS' should be replaced by 'Systemic Exertion Intolerance Disease' (SEID). So why is 'ME/CFS' still even a thing, it's a contradiction and oxymoron


There have been many attempts to define CFS, some of them described in our 1992 book :


M.E. (also known as Enteroviral Encephalomyelitis) and ME/CFS represent a complex, multi-system group of afflictions, adversely affecting the brain, heart, neuro-endocrine, immune and circulatory systems in our bodies, but, crucially, M.E. (also known as Enteroviral Encephalomyelitis) is a distinct illness, while both CFS and ME/CFS are "umbrella terms" for a group of symptoms common to many illnesses and conditions. 

This has led to M.E. symptoms being confused with the symptoms for neurasthenia,...

...multiple chemical sensitivities, fibromyalgia,...

...chronic mononucleosis, and much more.

The US Centers for Disease Control and Prevention (CDC) first defined CFS, with great emphasis on the word “FATIGUE”, in 1988. This definition, referred to as “Holmes”,...

A Symptom List: Clearly an Enterovirus Symptom List. 

The Holmes CFS and Fukuda CFS Symptom-Based Criterias/Checklists overlap with 'Enteroviral Encephalitis' but this list is closer to 'Enteroviral Encephalomyelitis' (also known as Epidemic Myalgic Encephalomyelitis) M.E. 

...was later replaced by the 1994Fukuda”,...


A similar symptom list as before but with Fatigue and Post-Exertional Malaise (PEM) added and Paralysis removed, which distorts it closer towards Enteroriviral Encephalitis (Missed Diagnosed "acute onset" CFS-type illness) and away from Enteroviral Encephalomyelitis (also known as Epidemic Myalgic Encephalomyelitis) M.E.

...then by the 2005Reeves”,...

...and most recently by the 2015 IOM (Institutes of Medicine) report, still emphasizing FATIGUE








...with M.E. (also known as Enteroviral Encephalomyelitis) resulting is a specific and distinct Neuromuscular Disorder... 


...and CFS being a partially overlapping Fatigue-based Illness,...

...and that it was not possible to replace both M.E. (also known as Enteroviral Encephalomyelitis) and CFS with a single diagnostic entity

Twisk also stated that the SEID Algorithm included some patients that did not meet either an M.E. (also known as Enteroviral Encephalomyelitis) diagnosis or CFS non-diagnostic criteria."

M.E. Definition Booklet, September 2011, by Byron Hyde, MD

"At the first meeting on the 27th of October 2005, the Chairman of the Joint Committee, Dr. Ian Gibson, asked me to prepare a report and definition that might assist the committee in its further deliberations. The following are my original recommendation. 

Dr. Bruce Carruthers, who chaired the 2003 Canadian Clinical Case Definition for ME/CFSwas also present when I gave this definition. 

I strongly disagreed with Dr. Bruce Carruthers in the merging of the definitions of M.E. (also known as Enteroviral Encephalomyelitis) and CFS since on basis of the physical total body assessment of both M.E. (also known as Enteroviral Encephalomyelitis) and CFS patients; these two names represent two entirely different spectrums of illnessesThe present 2016 definition is confined to the defining of Myalgic Encephalomyelitis (M.E.)."

"The term CFS is mentioned from time to time to clarify differences. It is increasingly obvious that too much importance was being placed upon the definitions of Chronic Fatigue Syndrome (CFS), and not enough upon the actual disease, Myalgic Encephalomyelitis (M.E.) (also known as Enteroviral Encephalomyelitis). These two illness spectrums are not the same and shouldn't be considered the same. Nor is there any doubt in my mind that the various definitions of CFS actively impede physicians' ability to make a rapid and rational diagnosis as well as a scientific confirmation of any testable illness. Such is not true of M.E. (also known as Enteroviral Encephalomyelitis) where a rapid and rational diagnosis can be confirmed by laboratory and other technological testing."

"In my 27-year investigation of M.E. (also known as Enteroviral Encephalomyelitis) and CFS patients, I can state with clarity that there is less psychiatric among M.E. (also known as Enteroviral Encephalomyelitis) or CFS patients than in the general public"

"Garbage Bag Disease: Unfortunately, many physicians appear to be using CFS (currently erroneously labelled ME/CFS) as a convenient garbage bag disease, simply telling patients whom they have no time to investigate, "Oh, you have Chronic Fatigue Syndrome". It is most unfortunate that the Americans, who have now promoted the idea that CFS is the same as M.E. (also known as Enteroviral Encephalomyelitis) have only compounded the disaster. Due to this garbage bag phenomena mentality many CFS patients are never properly investigated for serious disease and most CFS patients have significant and often treatable pathologies."



REDEFINITIONS of M.E. and CFS - A 20TH CENTURY PHENOMENON by Dr. E.G. Dowsett MB ChB Dip.Bact


The pathology of Chronic Fatigue Syndromes are poorly understood, and they can be difficult conditions to diagnose because there is no standard test, many symptoms are non-specific.

Subgroup Analysis suggests that, depending on the applied definition, Chronic Fatigue Syndrome may represent a variety of conditions; rather than a single disease entity

The CCC was updated and replaced in 2011 by the International Consensus Criteria (ICC) which insisted that CFS should not be considered a diagnostic entity and that M.E. (also known as Enteroviral Encephalomyelitis) is a specific diagnosis requiring thorough patient history, examination, and testing. 

International Consensus Criteria (ICC) - Adult & Paediatric: International Consensus Primer for Medical Practitioners - Bruce Carruthers & Marjorie van de Sande (Invest in M.E., 2011)


International Consensus Criteria (ICC) - Bruce Carruthers (Journal of Internal Medicine, Wiley, 2011)

Unfortunately the CDC did not accept or adopt the ICC, written by 26 so-called experts (Only, Dr. John Chia, Dr. David Bell Dr. Ismael Mena, really... is any kinda expert?) in the field, and instead commissioned it's own group with limited access to M.E. (also known as Enteroviral Encephalomyelitis) information, to create their vague 2015 IOM report, minimizing the disease yet again. 

This is the report most widely used and accepted throughout the world today (2025). 

[except of course for those countries and organizations that still use only “CFS”, or worse, also classify this “CFS” as a psychiatric condition,...

Cranial Nerves - Cleveland Clinic


Functions and Dysfunctions of The Cranial Nerves 

Most Commonly Reported

1. Abducens Palsy (CN VI) - Symptoms: horizontal diplopia, impaired outward gaze (eye can’t abduct), inward deviation (esotropia)

2. "Peripheral" Facial Palsy (CN VII) - Symptoms: facial weakness or asymmetry, inability to close eye or smile symmetrically, drooping of mouth, sometimes loss of taste on anterior tongue


"Peripheral" Facial Palsy (Lower Motor Neuron)

3. Bulbar Palsy (CN IX, X, XII, XI) - 


b) Dysarthria (Slurred/Nasal Speech)

c) Absent Gag Reflex

d) Nasal Regurgitation

e) Weak or Paralyzed Tongue (atrophy/deviation if XII involved)

d) Risk of Aspiration, and Respiratory Failure (Major cause of death in Bulbar Poliomyelitis)

Intermediate Frequency

4. Oculmotor Palsy (CN III) - Symptoms: ptosis (drooping eyelid), ophthalmoplegia (eye can’t move in all directions), dilated/fixed pupil, diplopia




5. Hypoglossal Palsy (CN XII) - Symptoms: tongue deviation to the affected side, fasciculations, atrophy, impaired speech and swallowing

6. Glossopharygeal Palsy (CN IX, isolated) Symptoms: impaired gag reflex, dysphagia, loss of taste sensation from posterior third of tongue (though often grouped into bulbar palsy)


Least Commonly Reported

7. Accessory Palsy (CN XI) - Spinal Accessory Palsy, usually with bulbar involvement, rarely isolated. Symptoms: shoulder droop, weak head turning (Sternocleidomastoid, Trapezius Weakness)

8. Trochlear Palsy (CN IV) - superior oblique palsy, uncommon, mostly isolated cases. Symptoms: vertical diplopia, difficulty looking down, compensatory head tilt

9. Trigeminal Palsy (CN V) - rare, trigeminal neuralgia / trigeminal neuropathy, isolated palsy uncommon. Symptoms: facial numbness, loss of corneal reflex, weakness of mastication muscles



Ménière's-like Syndrome


Enteroviral Encephalomyelitis can cause a Ménière's-like Syndrome (same triad: vertigo, tinnitus, hearing loss).

The mechanism would most likely be direct viral/immune damage to CN VIII or the inner ear, not the classic endolymphatic hydrops of idiopathic Ménière's Disease.

So, in strict terms: it causes a secondary Ménière's-like Syndrome/Picture, but it’s not considered “true” Ménière's Disease.

11. Optic Palsy (CN II) very rare - optic neuritis (optic neuropathy), Symptoms: blurred vision, visual loss, central scotoma



Motor Neuron Pathways potentially affected in Post-Enteroviral M.E. 


...is still not specific enough.



Jonathan Edwards (Emeritus Professor of Connective Tissue Medicine at University College London (UCL) and "CFS Criterias advocate" over at "Pseudo Science for CFS Criterias" forum, which "diagnose" precisely nothing?)


Jonathan Edwards claims 'ME/CFS' is fairly much what Dr. Melvin Ramsay called Chronic M.E.. It is not though because "ME/CFS" is two 'UNEXPLAINED FATIGUE' State criterias, 'Symptom-Based Checklists' that define precisely NOTHING characterized by CHRONIC or PROFOUND FATIGUE, one invented in 2003 by Dr. Bruce Carruthers and the other invented in 2015 by Ron Davis

Myalgic Encephalomyelitis (also known as Enteroviral Encephalomyelitis) M.E. is an "acute onset" diagnosable neurological disease. Jonathan Edwards claims M.E. physicians are the ones who confuse Polio-like M.E. with The Concept of 'ME/CFS'. 

It is obviously 'CFS' criteria creator inventors, who have conflated Myalgic Encephalomyelitis (also known as Enteroviral Encephalomyelitis) M.E. with 'non-specific' criterias, defined by FATIGUE; in which it is EXCLUDED from; as an 'acute onset' medically 'diagnosable' neurological disease. 

Jonathan Edwards claims there is no special neurological disease that warrants the M.E. name. Jonathan Edwards has absolutely no evidence for this claim. Then goes on to claim the psychiatrists Colin McEvedy and William Beard may have been right about their view on M.E.

Concept of Benign Myalgic Encephalomyelitis - Colin McEvedy & William Beard (BMJ, 1970)


Jonathan Edwards then goes on to claim M.E. is a 'non-existent' neurological disease. 

EBV doesn't happen in 'epidemics' and it has a incubation period of between 4-6 weeks.

Infectious Mononucleosis (also known as Glandular Fever)


Royal Free Epidemic patients fell ill with an 'Encephalomyelitis' caused by an Enterovirus; which Jonathan Edwards claims doesn't exist!?



Epidemic Myalgic Encephalomyelitis (also known as Enteroviral Encephalomyelitis) M.E. is EXCLUDED from 'ME/CFS' criterias and IS NOT THE SAME THING AT ALL. 

'ME/CFS' is designed to capture 'heterogeneous' undefined 'Chronic Fatigue Syndromes'. 


Jonathan Edwards then says his 'conclusion' is that M.E. (also known as Enteroviral Encephalomyelitis) never existed. 

We should focus on the 'non-existent disease' of 'ME/CFS' instead. 

The ICC did include M.E. (also known as Enteroviral EncephalomyelitisSPECT Scans for a specified pathology, within the criteria. 

It's actually the 'ME/CFS' criterias, which include 'no specific defined pathology', within the criterias. 

Jonathan Edwards has been historically and publically disparaging towards people who have actually fallen sick and disabled to Epidemic Myalgic Encephalomyelitis (also known as Enteroviral EncephalomyelitisM.E. as well as their experts, over at Science for M.E. forum, which doesn't seem to do any real Science for M.E. but is a social commentary forum, abit like a Reddit of the Pseudo Science World of CFS Research Criterias

It is ironically not really an M.E. (also known as Enteroviral Encephalomyelitis) forum. 

Jonathan Edwards has questioned and dismissed M.E. (also known as Enteroviral Encephalomyelitis) very existence, as a "distinct and specific neurological disease entity" that exists, and has also "dismissed" people, who want to advocate specifically for Enteroviral Encephalomyelitis, and claims that it doesn't really even exist and calls people like Dr. Melvin Ramsay as FRINGE

In doing so, he is no different to the rest of the medical profession, who "questions" and "dismisses" M.E. (also known as Enteroviral Encephalomyelitis) very existence as a specific disease entity

The great irony is individuals such as Dr. Melvin Ramsay were ahead of their time,...

...and had vastly more scientific credibility, than your average doctor, or individuals such as Jonathan Edwards, who is arrogant beyond any reasonable measure or belief

The irony is that Jonathan Edwards has done an ode to Colin McEvedy and William Beard in this paper title :

The Concept of ME/CFS by Jonathan Edwards (Qeios, 1st November, 2024)

His views and opinions are not conducive with being an Epidemic Myalgic Encephalomyelitis (also known as Enteroviral Encephalomyelitis) M.E. advocate and supporter of the M.E. cause. 



In creating the Nightingale Definition, we have studied decades of clinical evidence, and followed up on the work of Dr. Melvin Ramsay (case descriptions published 1986 and 1988),...


...Dr. Elizabeth Dowsett

...Dr. John Richardson


...and others who closely studied M.E. patients and M.E. outbreaks over several decades.

List of Outbreaks of Myalgic Encephalomyelitis (also known as Enteroviral Encephalomyelitis) and Holmes Chronic Fatigue Syndrome (also known as Enteroviral Encephalitis) - MEPedia







M.E. (also known as Enteroviral Encephalomyelitis) has a clearly defined disease process, while CFS by definition has always been a syndrome. In light of this state of affairs, the Nightingale Research Foundation created its 2007 Definition of M.E. and updated it in 2016. Our Nightingale Definition of M.E. is located on our website under "Publications" and is available as a free download in English, French, Norwegian, and Danish.

The Complexities of Diagnosis 

In 2003, Dr. Byron Hyde completed a chapter for L. A. Jason, P. A. Fennell and R. R. Taylor for their book Handbook of Chronic Fatigue Syndrome, John Wiley and Sons Inc., Hoboken N.J., titled “The Complexities of Diagnosis” 1, Chapter 3. This chapter includes the following definition of CFS: 

The physician and patient alike should remember that CFS is not a disease. It is a chronic fatigue state where the one essential characteristic of M.E. is "acquired" Central Nervous System (CNS) Dysfunction, that of CFS is primarily Chronic Fatigue. By assumption, this CFS fatigue can be "acquired" abruptly or gradually. Secondary symptoms and signs were then added to this primary fatigue anomaly. None of these secondary symptoms is individually essential for the criteria and few are 'scientifically' testable. Despite the list of signs and symptoms and test exclusions in these definitions, patients who conform to any of the CDC, Oxford, Australian and Canadian CFS criterias may still have an undiagnosed major illness, certain of which are potentially treatable. Although the authors of these definitions have repeatedly stated that they are defining a syndrome and not a specific disease, patient, physician, and insurer alike have tended to treat this syndrome as a specific disease or illness, with at times a potentially specific treatment and a specific outcome. This has resulted in much confusion, and many physicians are now diagnosing CFS as though it were a specific illness. They either refer the patient to pharmaceutical, psychiatric, psychological, or social treatment or simply say: “you have CFS and nothing can be done about it”. The CFS criterias have another curiosity. If in any CFS patient, any major organ or system injury or disease is discovered, the patient is removed from the definition. The CFS criterias were written in such a manner that CFS becomes like a desert mirage: The closer you approach, the faster it disappears, and the more problematic it becomes.”

Definition Essentials 

Some of the definition essentials required to accurately diagnose either M.E. (also known as Enteroviral Encephalomyelitis) or CFS, or any chronically ill patients group, include:

  • A working case clinical definition must be short, clear and testable.

  • Patients and their illness or illnesses must be part of an integrated system. Neither the patients’ pathophysiology nor their illness can be understood without a concise knowledge of their integrated pathophysiological systems.

  • A statistically significant group of patients who have M.E. (also known ss Enteroviral Encephalomyelitis) and CFS-type illnesses must be subjected to a complete personal and family history to map the genetic and historical causes of their illnesses. 

  • Accordingly, the patient’s illness can only be understood if a complete total body mapping is performed on all systems and organs. The mammalian and animal bodies are an integrated physiological mechanism and when one major system change occurs, many physiological systems are liable to shift

  • In the past it has been facile to pose psychiatric diagnoses on M.E. (also known as Enteroviral Encephalomyelitis) and CFS patients since psychiatric diagnoses cannot be subjected to scientific examination. Psychiatrists rarely actually examine patients and almost never do an integrated pathophysiological patient investigation of the patient’s organs and systems. Nor have most psychiatrists been of any help in diagnosing M.E. (also known as Enteroviral Encephalomyelitis) and CFS patients except to the insurance industry. In the more than 70 years since the first major M.E. (also known as Enteroviral Encephalomyelitisand original CFS (also known as Enteroviral Encephalitis) epidemic struck the Los Angeles County General Hospital in 1934no psychiatric treatment has proven significantly effective in treating the M.E. (also known as Enteroviral Encephalomyelitis) and heterogeneous CFS group of patients and restoring them to health. This is understandable since neither represents a psychiatric disorder. 

  • Effective treatment of the M.E. (also known as Enteroviral Encephalomyelitis) and heterogeneous CFS group of patients depends upon precisely defining the organ and system pathologies and learning how to treat these pathophysiological conditions. 

  • M.E. (also known as Enteroviral Encephalomyelitis) and the hetrogeneous CFS group of illnesses are chronic illnesses. For too long physicians have been considering chronic diseases and chronically ill patients as they would acute short-term illnesses. We believe this is an error and we direct those interested to our chapter on diagnosis. Relatively young chronically ill patients, often do not have a disease process, they often have many disease processes.

NO, THEY ARE NOT THE SAME. 



No, this is not the same as Epidemic Myalgic Encephalomyelitis (also known as Enteroviral Encephalomyelitis) M.E. 


Epidemic Myalgic Encephalomyelopathy - The Free Dictionary by Farlex

ep·i·dem·ic my·al·gic en·ceph·a·lo·my·e·lop·a·thy

a disease superficially resembling poliomyelitis, characterized by diffuse involvement of the central nervous system associated with myalgia.

There fact there are numerous CFS criterias that do not define a single disease, and which are a diagnosis of exclusion, should lead any legitmate researcher, to question their credibility and legitimacy


They are calling "Chronic Fatigue Syndrome" as "ME/CFS" and for sure has "subgroups" because it's based upon a short diagnosis of exclusion "symptom-based" checklist criteria, characterised by "Profound Fatigue"

Nightingale is pleased to offer the definition of Myalgic Encephalomyelitis in a downloadable PDF format for free in the following translations:

Nightingale Research Foundation - MEPedia

The Nightingale Research Foundation Definition is a definition of Myalgic Encephalomyelitis that was developed by the Nightingale Research Foundation. It was first presented as a preliminary draft in 2006, published in 2007, and updated in 2016.

Definitions, Abbreviations and Acronyms

EV = Enterovirus: (incubation period circa 3-7 days) (illness beginning most frequently in late summer and autumn in the north temperate world) (these infections first enter the body through the gastric portal, hence the name: entero. 

Enteroviruses cause paralytic polio, other paralytic enteroviral diseases, type 1 diabetes, major gastric diseases.


Genome - The complete set of genes or genetic material which defines a micro-organism.

M.E. - Epidemic Myalgic Encephalomyelitis: a complex epidemic and sporadic biphasic disease state caused by a chronic enteroviral infection, which injures the GIT system and the upper CNS brain function. CNS dysfunction, in turn, causes generalized body dysfunctions.

CFS = Chronic Fatigue Syndrome: CFS is not a disease. It is a non-specific group of poorly investigated chronically disabling and major illnesses, diseases and pathologies.

EBV = Epstein Barr Virus is the primary cause of Mononucleosis (Glandular Fever in the UK): This is an easily diagnosed viral illness that due to its circa 40 day incubation period does not cause epidemic diseases. Unlike Enteroviral infections there is no specific season when it is more common.

CNS = Central Nervous System: (brain, brainstem, spinal cord and appendages).

MRI = Magnetic Resonance Imaging: Used as brain imaging technology. This technique visualizes anatomy not function. Routine MRI cannot demonstrate most physiological brain dysfunction.

SPECT = Single Photon Emission Computed Tomography: This technique visualizes physiological function or vascularization, not anatomy. SPECT can document major brain dysfunction.

HMPAO = A nucleotide (Hexa-Methyl-Propylene-Amine-Oxime) used in SPECT imaging and the essential product for brain mapping employing Segami Oasis NeuroGam software.

Dysautonomia = a malfunction of the autonomic nervous system seen in many severe M.E. patients, specifically Insular hypoperfusion. (Several brain areas are responsible for normal blood pressure, efficient body and CNS circulation, and normal heart rate.)

PoTS = Postural Orthostatic Tachycardia Syndrome: (This is a variety of dysautonomia.)

Insular Lobe = a hidden lobe covered by the operculum (the junction of the temporal, parietal, frontal lobes). The insular lobe is the brain area significantly responsible for autonomic control. Hypoperfusion of the operculum is consistently found in patients with Dysautonomia.

GIT = Gastrointestinal Tract: (oesophagus, stomach, small and large intestines)

CDC = Centers for Disease Control and Prevention: (Atlanta, Marietta Georgia)

NIH = National Institutes of Health (Bethesda, Maryland) One of the world’s foremost medical research centres, an agency of the USA Department of Health.

To the reader,

The following information explains how physicians can diagnose clinically & test scientifically for Myalgic Encephalomyelitis (M.E.) (also known as Enteroviral Encephalomyelitis). 

But, first a word about M.E. (also known as Enteroviral Encephalomyelitisand EnteroViral (EV) infections. 

M.E. is not Chronic Fatigue Syndrome (CFS). 

M.E. (also known as Enteroviral Encephalomyelitis) is an epidemic and sporadic illness caused by many E.V.sThe best known E.V.s are Polio 1, 2 & 3 but the genomes of the approximately 100 different E.V.s are identical to the polio genome except for a 5% difference in the 5’ (prime) untranslated area.

Most interesting is that the first-year symptoms of M.E. (also known as Enteroviral Encephalomyelitis) are identical to Dr. Ivar Wickman’s description of the Polio symptoms in the 1905 Stockholm-area polio epidemic, which maimed and killed over 1031 patients. 



The principal differences between polio and M.E. (also known as Enteroviral Encephalomyelitis) is that E.V.s injure primarily the upper CNS:

a. E.V.s injure the CNS, primarily above the spinal cord; whereas Polio E.V.s injure the spinal cord, brainstem, & to a lesser extent the brain itself.

b. Certain E.V.s have always caused paralysis but not usually as frequently nor as severely as polio 1 & 3, although many of these E.V.s can cause muscle weakness as in M.E. In addition, E.V.s cause a large number of other serious and often fatal illnesses, both in children and adults.

c. Polio immunization researchers didn’t know about E.V. until after the first successful Salk polio vaccine. In effect, they built the polio-immunization on the basis of the 5’ prime area of the genome (at the left of the following diagram). If they had built the immunization on the basis of the VP3 section of the genome below, were it possible, there would be no M.E. (also known as Enteroviral Encephalomyelitis) today, nor would there be any paralytic polio either.

There are many causes of viral and chemical brain injury but M.E. (also known as Enteroviral Encephalomyelitis) is only caused by Enteroviruses (E.V.). Today, it is likely that in most cases, Lansing Polio 2 virus would be considered to be an M.E. virus since it causes significantly less flaccid paralysis than polio 1 & 3. Many of the same E.V.s that cause M.E. (also known as Enteroviral Encephalomyelitis) can also cause flaccid paralysis simulating polio. Example, E.V.s 68 & 70 and at least another 10 E.V.s. In effect, they might all be called polio today and there is no immunization for them.

Epidemic Myalgic Encephalomyelitis (also known as Enteroviral Encephalomyelitis) M.E. is described in this booklet and is caused by enteroviruses.

Acute Onset missed diagnosed Chronic Fatigue Syndromes can be associated with any CNS (neurotropic) injuring or infectious agent. Childhood infections in adults (usually adults over 20 yrs.) such as varicella (chicken pox), measles, EBV, can cause death or chronic brain dysfunction, which can provoke the so-called CFS-type patients. But EBV can never cause rapidly-spreading epidemics.

Chronic Fatigue Syndrome (CFS): in our experience the diagnosis of CFS only means the investigating physicians have not thoroughly investigated the patient. 

We routinely find in US, Canadian and European CFS patients diagnosed by physicians in their country, a variety of missed diseases. These include: toxic & chemical injuries, genetic injuries, cardio and cardio-vascular injuries, collagen diseases, adverse medication reaction, mitochondrial disease, adverse immunization caused illness, Ehlers-Danlos Syndrome, rarely M.S., missed thyroid malignancy and thyroid diseases. CFS in general implies a serious missed disease. I have found up to 20 significant pathologies in a single CFS patient, none of them caught by any physician. Yet they are diagnosed as CFS. Fibromyalgia is also a legitimate symptom in over 10 different classically-accepted illnesses. 

See our book: Missed Diagnoses at Lulu.com. 

I believe CFS is not a disease or a syndrome, but is a mixed group of undiagnosed significant illnesses.

The CDC 1988 CFS publication, based on the summer 1984 Lake Tahoe epidemic, was a classic enterovirus epidemic & not an EBV infection. The authors of the 1988 CDC definition quoted EBV research publications almost exclusively, believing this to be an Epstein Barr epidemic. They also appear to have crafted the CFS diagnostic criteria to fit their EBV prejudice. One rarely ever found swollen cervical glands in M.E. (also known as Enteroviral Encephalomyelitis) patients. The CFS authors should have known, EBV, with an incubation period of 40 days, can never have caused the rapidly spreading epidemic across Nevada & North America. Also, EBV does not have a late summer early autumn peak. Late summer and autumn is enterovirus territory.

The so-called Oxford Guidelines were created primarily by a large group of UK psychiatrists, in attempt to receive NIH funds. However, they crafted their CFS definition as a psychiatric illness. This intentional prejudice has been disastrous for many M.E. (also known as Enteroviral Encephalomyelitis) patients in the UK, as it succeeded in the psychiatric-ization of this epidemic post-infectious CNS-injuring illness. The dangerous practices of CBT, GET and PACE treatment do not result in recovery in true M.E. (also known as Enteroviral Encephalomyelitis) brain-injured patients any more than if CBT had been used to treat paralyzed polio patients. In our experience, CBT & GET are often employed to nullify disability pensions since true M.E. (also known as Enteroviral Encephalomyelitis) patients cannot continue such treatments without further damage.

Today, many UK, Northern American & European patients are routinely dismissed, rarely correctly investigated and too often placed on a psychiatric treatment, or hospitalized against their will due to the Oxford & CDC definitions. They base their diagnosis upon the fallacious concept: a patient with only symptoms and no physical or positive test findings is a psychiatric patient. This is why correct tests for M.E. (also known as Enteroviral Encephalomyelitis) must be performed as described in this booklet.

I am in turn critical of the New England Journal of Medicine, one of the world’s best medical journals, for making the late Dr. Stephen Straus... 

...one of the three secret peer reviewers of CFS and M.E. (also known as Enteroviral Encephalomyelitis) papers. 


His blocking of the Dr. Dan Peterson et al Lake Tahoe paper destroyed any honest understanding of this tragic epidemic. No medical journal should place a peer reviewer on their board who has a financial stranglehold on publications as had Straus, the chair for CFS funding at NIH. I am also critical of the CDC & NIH, having given no serious funding to investigate chronic patients of this 1984 Tahoe epidemic, North American illness, which has resulted in the chronic disability of tens of thousands of Americans and Canadians.

This Nightingale Research Foundation Definition for M.E. is particularly important to physicians since the cause of M.E. (also known as Enteroviral Encephalomyelitis) is related to chronic enteroviral infections, close cousins of paralytic poliomyelitis. At the August Europic 2016 meeting on picornaviruses & enteroviruses in Switzerland, several new anti-enteroviral medications were discussed, including: Pirodavir, Vapendavir, Pocapavir, Pleconaril & Rupintrivir. Although at an early stage, some have shown success in animal models. Help may yet be on the way for chronically-disabled M.E. (also known as Enteroviral Encephalomyelitis) patients. Prevention is always better than treatment. Prevention can only occur with a new enterovirus immunization which would not only stop M.E. and polio from occurring, but would prevent many type 1 diabetes and and many deaths in millions of children world wide who die every year due to EV diarrhea and pneumonia.


Nightingale Research Foundation Definition (2007)



M.E. (also known as Enteroviral Encephalomyelitis) is a chronic disabling, acute onset biphasic epidemic or endemic (biphasic) infectious disease process affecting both children and adults. 


The Clinical History

M.E. (also known as Enteroviral Encephalomyelitis) is a biphasic illness: The acute & chronic symptoms are identical to the onset symptoms in poliomyelitis patients as described by Ivar Wickman* in 1905, only lacking paralysis. As in polio & most enteroviral (E.V.) infections, M.E. (also known as Enteroviral Encephalomyelitis) tends to onset in late summer and autumn

As in Polio, the incubation period is usually from 3-7 days in humans, possibly depending on viral load. M.E. (also known as Enteroviral Encephalomyelitis) is seen in both sexes and at any age, including children, but tends to be most frequently a post-pubertal illness with circa 67% occurring in females, suggesting an autoimmune role (asymptomatic carriers who then infect others may create the appearance of a longer incubation period).

First Phase, The Acute Illness: The first phase symptoms can be minor or missed, resembling 


(b) a significant flu-like illness with headaches, malaise and/or gastric upset, or 

(c) the first evidence of disease can be the severe second-stage symptoms. Elevated temperature might occur but normal or slightly subnormal temperatures are usual. Patients may complain of feeling feverish or having chills and sweats. M.E. (also known as Enteroviral Encephalomyelitis) is rarely taken seriously at onset & mistaken as influenza, EBV or a short term illness. It is essential for the investigating physician to order E.V. tests to make this diagnosis


Second Phase: Chronic Illness: The severe second phase is diagnostic of the illness and in cluster and epidemic situations tends to begin anywhere from day 1 to day 10 following the initial onset phase. 

Physical signs tend to be limited.

The symptoms of the second phase are divided into two parts:

1. Second Phase, Part One: The second phase can include the symptoms of the first phase plus:

a. Apparently inexplicable severe crippling exhaustion: The patient experiences overwhelming physical lassitude, and may appear semi-conscious and not wanting to move, often due to pain.

b. Pain: Pain may be described as either mild or severe, persisting, transitory or fleeting. There tends to be persisting malaise & migratory pain and infrequently polyarthritis. Pain may include severe headaches and retro-orbital eye pain, visible muscle spasms, chest and abdominal pain. Headaches can be severe as seen in encephalopathy. Many pain syndromes and their intensity tend to decrease over time. Narcotic use can cause persistence and addiction. Their use is cautioned. Narcotic withdrawal can cause increased pain.

(Pain should be treated if patient asks for it and even with opioids, and other pain killers, as it can be suicidal level pain, in intensity)

c. Paresthesias: (pins & needles) in extremities often occurs, causing physicians to consider multiple sclerosis, but CNS-MRI rarely demonstrate any significant abnormalities. Lumbar puncture in first two weeks may show

(a) oligoclonal banding suggesting neuronal injury, 

(b) increased pressure and sometimes 


d. Fear: The patient often feels so ill they believe they are dying. A sense of impending doom may prevail. If the patient is sufficiently conscious, anxiety can be a common early complaint. 

Compassion and physician understanding help are warranted, as well as understanding that increasing activity, too early within the disease process, can worsen the disease.

e. Lack of Physical Signs: Unless 

(a) EV tests are ordered at onset or 

(b) EV GIT mucosa tests are examined in chronic patients or 

(c) appropriate brain SPECT mapping is requested, the most startling finding is the almost total lack of significant physical signs or positive routine tests commensurate with the patient’s severe symptomatic complaints & disability. Temperature increase, cervical glands, neurological signs are absent or infrequent. Inappropriate, routine lab tests tend to be negative. Due to largely negative physical findings the physician may consider the patient’s illness hysterical or anxiety-based. MRI, X-Ray, CT scans and routine blood tests are poor diagnostic tools for a scientific diagnosis of M.E. (also known as Enteroviral Encephalomyelitisbut are important to exclude other major diseases.

2. Second Phase, Part Two: The severely disabling and chronic aspects of M.E. (also known as Enteroviral Encephalomyelitis) tend to be recognized once the early acute complaints become subdued or the new norm. This phase tends to manifest itself over the next two or more weeks and occurs when the patient attempts to mobilize themself or return to normal pre-illness activity, school or work. Any return to even a reduced physical or intellectual activity can be seriously problematic. The acute disability may persist for months. Major activity at this time has infrequently resulted in deaths. The patient becomes aware of major disabling, persisting and disquieting intellectual and physical changes which can include:

Neurological Associated Symptoms: These may become permanent but are more significant in early illness.

a. Many CNS difficulties may occur: 

(a) short term memory impairments 
or dysfunctions, 

(b) mathematical or dyscalculia difficulties, 

(c) difficulty remembering written material just read, 

(d) anomia


(f) word dysfunction. 

Ataxia, near syncope or syncope, confusion
disorientation are common; (Bastien, S*) 

b. Auditory, inner ear changes can occur frequently. Presbycusia, auditory pain, balance difficulties and the inability to appreciate music, due to "acquired" tone deafness may occur;

c. Particularly during the first weeks or months, visual abnormalities & distortions can occur regularly, including tunnel vision, spatial perception & distance judgment difficulties, visual agnosia, loss of night vision, colour perception, retro-optical eye pain, mild to severe light intolerance is frequent. Rarely, these can become permanent.

d. Persisting 

(a) Raynaud’s-like sensory changes in the extremities, peripheral coldness 

(b) menopausal-like sweats can occur in both men and women, 

(c) the inability to maintain a normal body temperature, are all frequent findings. 

These neurological complaints can falsely suggest Vitamin B12 deficiency or M.S.

e. Inability to return to a normal physical state after minor physical activity is diagnostic. Post-activity disability can continue for days. Forced activity in our experience has resulted in death & in permanent house bound invalids. The young patient (16-60 years) describe themselves as becoming overnight, an ill 80-90 year person;

f. Major sleep dysfunctions, sleep reversals, hypersomnia and failure of restorative sleep become the norm. At onset, sleep can be associated with terrifying dreams;

g. Neurogenic Bladder (Bladder Dysfunction) and Interstitial Cystitis commonly seen in polio and simulating bladder infection, also polyuria, interstitial cystitis and nocturia are frequent in women;

h.Tachycardia, hypotension, dysautonomia, PoTS or hypertension can occur on minor activity & are often mistakenly dismissed by physicians as a result of inactivity:

For multiple and sometimes treatable causes of fibromyalgia and CFS, see: Missed Diagnoses: Lulu.com

There are both central and peripheral aspects to this illness.

A) The Central Nervous System (CNS) symptoms, as well as the clinical and technological abnormalities, are caused by a diffuse and measurable injury to the vascular system of the Central Nervous System. These changes in the organization of the CNS are caused by a combined infectious and immunological injury and their resulting effect on CNS metabolism and control mechanisms. Much of the variability observed in an M.E. (also known as Enteroviral Encephalomyelitis) patient’s illness is due to the degree and extent of the CNS injury and the ability of the patient to recover from these injuries.

B) A significant number of the initial and long-term peripheral or body symptoms, as well as clinical and technological body abnormalities in the M.E. (also known as Enteroviral Encephalomyelitis) patient, are caused by variable changes in the peripheral and CNS vascular system. The vascular system is perhaps the largest of the body’s organs and both it's normal and pathophysiological functions are in direct relationship to CNS and peripheral vascular health or injury, to CNS control mechanisms and to the difficulty of the peripheral vascular system and organs to respond to CNS neuro-endocrine and other chemical and neurological stimuli in a predictable homeostatic fashion.

C) When pain syndromes associated with M.E. occur, they are due to a combined injury of 

(i) the posterior spinal cord and / or posterior root ganglia and appendages

(ii) pathophysiological peripheral vascular changes, and 

(iii) CNS pain reception homeostasis mechanisms.

Depending upon the degree and extent of the ongoing CNS and peripheral vascular injuries, these pathophysiological changes in turn may give rise to both transient and in many cases permanent systemic organ changes in the patient.

As with any illness, the diagnostic criteria of M.E. (also known as Enteroviral Encephalomyelitis) are divided into two sections:

(a) The clinical features and history of the ill patient that alert the physician to the initial diagnosis, and

(b) The technological examinations that confirm to the physician proof of his diagnosis.

Clinical Features

The clinical features of Myalgic Encephalomyelitis (also known as Enteroviral Encephalomyelitisare consistent with the following characteristics that can easily be documented by the physician.

Biphasic Epidemic or Endemic (Sporadic) Infectious Disease Process

Both Epidemic and Non-Epidemic cases are often preceded by a series of repeated minor infections in a previously well patient that would suggest either a vulnerable immune system, or an immune system subject to overwhelming stressors such as:

a. Repetitive contact with a large number of infectious persons,

b. Unusually long hours of exhausting physical and / or intellectual work,

c. Physical traumas,

d. Immediate past immunizations, particularly if given when the patient has concurrent allergic or autoimmune or infectious disease or if the patient is leaving for a third world country within three weeks of receiving the immunization,

e. Epidemic disease cases whose onset and periodicity appear to occur cyclically in a susceptible population,

f. The effect of travel, as in exposure to a new subset of virulent infections, or

g. The effects of starvation diets.

(It should be noted that subsets c, d, e, f and g are all stressors associated with decreased immune adaptability plus an associated infection with an appropriate neurovascular infectious virus or other infectious agent. This may be due either to an immediate preexisting infectious disease or to a closely following infection, either of which may or may not be recognized.)

2. Primary Infection Phase

The first phase is an epidemic or endemic (sporadic) infectious disease generally with an incubation period of 4 to 7 days; in most, but not all cases, an infection or infectious process is evident(See Clinical and Scientific Basis of M.E. and CFS, Chapter 13, pps. 124-126)

3. Secondary Chronic Phase

The second and chronic phase follows closely on the first phase, usually within two to seven days; it is characterized by a measurable diffuse change in the function of the Central Nervous System. This second phase is the persisting disease that most characterizes M.E. (also known as Enteroviral Encephalomyelitis)

4. The Presence or Absence of Various Pain Syndromes is highly variable

The pain syndromes associated with the acute and chronic phases of M.E. (also known as Enteroviral Encephalomyelitismay be described as Early and Late findings.

Early Findings:

a. Severe headaches of a type never previously experienced;

b. These are often associated with Neck Rigidity (Stiff Neckand...

...Occipital Head Pain and Headache;

c. Retro-Orbital Eye Pain;

d. Migratory Muscle Pain (Myalgia)

...and Arthralgia (Joint Pain);

e. Cutaneous Hypersensitivity (Muscle Tenderness).

Late Findings: Any of the early findings plus:

  1. Fibromyalgia-like Pain Syndromes. This is only a partial list of the multiple pain syndromes. Many of the pain features tend to decrease over time but can be activated or increased by a wide range of external & chemical stressors(See Clinical and Scientific Basis of M.E. and CFS, Chapter 5, pps. 58-62)


Testable & Non-Testable Criteria

The technological tests listed below can be used to :

(a) Confirm the clinical diagnosis of Myalgic Encephalomyelitis (also known as Enteroviral Encephalomyelitis) and 

(b) To some degree gauge it's severity and probability of persistence. The second and chronic phase that clearly defines M.E. (also known as Enteroviral Encephalomyelitis) is characterized by various measurable and clinical dysfunctions of the cortical and/or sub-cortical brain structures.

5. Diffuse Brain Injury Observed on Brain SPECT

If the patient’s illness is not measurable using a dedicated brain SPECT scan such as a Picker 3000 or equivalent, then the patient does not have M.E. (also known as Enteroviral Encephalomyelitis) For legal purposes these changes may be confirmed by PET brain scans with appropriate software and /or QEEG. These changes can be roughly characterized as to severity and probable chronicity using the following two scales: 

A) Extent of injury and 

B) Degree of injury of CNS vascular function.


Initial Disease Severity:

1. Depending upon the degree of upper CNS injury the patient’s illness varies.

2. Those with minor CNS injury tend to recover better.

3. Those with major CNS injury as indicated in the brain SPECT's tend to recover only partially or not at all.

4. Total bed rest is essential during the first two or three months.

5. Then from 3-6 months, a very slow return to modest activity, if possible. It may take years to recover reasonable functionality. Even mild injuries never fully recover all CNS facilities. Major injuries may never recover pre-illness abilities.

6. The younger the patient the better the chance of recovery.

7. M.E. (also known as Enteroviral Encephalomyelitis) is additive in patients with collagen diseasesasthma, genetic associations (Ehlers Danlos Syndrome) or other chronic illnesses.

8. Avoidance of exposures and emotional tensions is essential during the first year.

Extent of Injury

Type 1: One side of the cortex is involved. Those patients labeled as 1A have the best chance of recovery.

Type 2: Both sides of the cortex are involved. These patients have the least chance of spontaneous recovery.

Type 3: Both sides of the cortex, and either one or all of the following: posterior chamber organs, (the pons and cerebellum), limbic system, the subcortical and brainstem structures are involved

Type 3B are the most severely affected patients and the most likely to be progressive or demonstrate little or no improvement with time.

Degree of injury

Type A: Anatomical integrity is largely maintained in the Brain SPECT scan.

Type B: Anatomical integrity is not visible in the CNS SPECT scan. Type 3B are some of the most severely and chronically injured patients.

Psychological Symptoms:

a. Psychological despair and reactive depression set in, particularly if the patient does not have support or disability pension access. The symptoms can be so severe, the fear the doctors are missing some terminal illness is a common patient sentiment. This becomes more evident when the patient’s physicians, due to unfamiliarity, are unable to find anything to explain the patient’s now chronic illness and their inability to return to the normal activity expected. Why? The illness has been mistakenly diagnosed as a typical short-term viral infection or influenza.

b. A sense of abandonment often occurs when friends and family members begin to drift away, and physicians begin to talk of a psychological diagnoses, depression and suggest antipsychotic medications, which if taken, often make the patient worse and if abruptly stopped by the patient due to side effects or lack of funds, has provoked many suicides.

6. Testable Neuropsychological Changes

There are neuropsychological changes that are measurable and demonstrate short-term memory losscognitive dysfunctions, increased irritability, confusion, and perceptual difficulties. 

There is usually rapid decrease in these functions after any physical or mental activity. Neuropsychological changes must be measured in relation to estimates of prior achievement. This feature may improve over a period of years in patients with adequate financial and social support and can be made worse by chronic stressors.

The neurophysiological changes are those observed by a qualified Neuropsychologist with experience in examining this type of disease spectrum. 

Some of the deficits that a Neuropsychologist should consider examining include:

a. Subtle problems with receptive and expressive aphasia,

c. Decreased concentration,


d. Distractibility and the decreased ability to process multiple factors simultaneously,
f. Decreased fine and gross motor problems,
g. Dysfunction of spartial perception,
h. Abstract reasoning,
i. Compromised visual discrimination,
j. Sequencing problems.

In Cochran’s Q Neuropsychological tests there is an increased observation of significant problems in both immediate and delayed verbal recall. In Dr. Sheila Bastien’s investigations, over 50% of M.E. (also known as Enteroviral Encephalomyelitis) patients have delayed visual recall, TAP dominance, TPT N-Dominance and 40% or more have abnormalities of Immediate visual recall, Tap N-Dom, Grip N Dominance, & grip dominance problems(Bastien, Sheila. The Clinical and Scientific Basis of M.E. and CFS. Chapter 51, pps. 453-460)

7. Testable Major Sleep Dysfunction

This can include all forms of Sleep Dysfunctions

All or any of the following may be present:

1. Impaired sleep efficiency,

2. Significant fragmented sleep architecture,

3. Movement arousals, particularly if there is an associated pain syndrome,

4. Absence or significant decrease of type 3 and 4 sleep,

5. Abnormal REM sleep pattern

6. Changes in daytime alertness and


Muscular Dysfunction:

a. After even minor activity, unusual persisting muscle weakness, malaise, inability to easily climb stairs without stopping occurs. A normal walking distance can cause patient days of muscle weakness and pain. Muscle spasms may occur early in illness.

b. Significant intercostal muscle pain, pleurodynia and spasm are common in the first years of illness and are often mistaken by the patient as cardiac symptoms.

8. Testable Muscle Dysfunction

This feature may be due to vascular dysfunction or peripheral nervous or spinal dysfunction and includes both pain and rapid loss of strength of muscle function after moderate physical or mental activity. This feature tends to improve over a period of years but many patients frequently remain permanently vulnerable to new disease episodes. Few centres are equipped or funded to make these examinations. Unfortunately only a few major medical centres are equipped to study this type of dysfunction.

9. Testable Vascular & Cardiac Dysfunction

This is the most obvious set of dysfunctions when looked for and is probably the cause behind a significant number of the above complaints. All moderate to severe M.E. patients have one or more and at times multiple of the following vascular dysfunctions. As noted, the primary vascular change is seen in abnormal SPECT brain scans and clinically most evident in patients with:

a) PoTS: severe Postural orthostatic Tachycardia Syndrome.

Note: This group can be confused with diabetes insipidus due to the fact that they may have polydipsia from their attempt to increase their circulating blood volume by consuming large amounts of fluids. This group can be verified by the absence of pituitary adenoma or pathology and the fact that they can sleep through the night without waking to drink fluids(Streeten, David)

Despite the great steps forward in the understanding of this relatively common pathophysiology seen routinely in M.E. (also known as Enteroviral Encephalomyelitis) patients, a pathology which is really related to either an autonomic injury to the CNS, injury to the vascular receptors or both, very little of the present treatment protocol is of much use. The situation is so bad that few major centres have any well-funded expertise in either autonomic or vascular receptor injury. Many of the M.E. (also known as Enteroviral Encephalomyelitis) patients that are dismissed by physicians as suffering from lack of activity have significant proprioceptive injuries in these areas. Nor can we always rely on the few autonomic laboratories and their tilt table testing abilities. Many of the tilt table examination reports return as normal, many as grossly abnormal. Yet all the physician has to do is have each M.E. (also known as Enteroviral Encephalomyelitis) patient stand for 8-12 minutes to realize that a large number of these normal tilt table patients simply cannot maintain a normal blood pressure and normal heart rate. Compare this to non-M.E. patients and one immediately can tell the difference. A large number of M.E. (also known as Enteroviral Encephalomyelitis) patients have significant autonomic difficulties.

b) Cardiac Irregularity: on minor positional changes or after minor physical activity, including inability of the heart to increase or decrease in speed and pump volume in response to increase or decrease in physical activity. (Hyde, B., Chapter on Cardiac Aspects): (Montague, T.,) Cardiac irregularity is closely related to the above discussion. In many M.E. patients there is an unusual daytime tachycardia, particularly since these patients are often very sedentary. In doing a 24-hour Holter monitor this may be missed since the 24 hour average is usually given. One should always ask for wake time and sleep time heart rates.

c) Raynaud's Phenomenon: vasoconstriction of small arteries or arterioles of extremities, with change in colour of the skin, pallor and cyanosis. It is associated with coldness and pain of extremities. This is in part, the cause for temperature and pain dysfunctions seen in M.E. (also known as Enteroviral Encephalomyelitis). This phenomenon is found in many other conditions than M.E. (also known as Enteroviral Encephalomyelitis) Some of the associations are post-traumatic, neurogenic conditions, occlusive arterial diseases, toxic chemical associations and a wide range of rheumatoid conditions. Many of these conditions have associations with M.E. (also known as Enteroviral Encephalomyelitis(See Magallni, S. for more detail.)




d) Circulating Blood Volume Decrease (Hypovolemia) : This is a nuclear medicine test in which the circulating red blood cell levels in some M.E. (also known as Enteroviral Encephalomyelitis) patients can fall to below 50%, preventing adequate oxygenation to the braingut and muscles. These patients do not generally have anemia and are not blood deficient. This is undoubtedly a subcortical dysregulation. It is associated with serum and total blood volume measurements. This is a concept that many physicians have difficulty understanding. 

I have heard physicians repeatedly tell the patient they are not aenemic and therefore dismiss this important finding.

Note: So where does the blood go? Body servomechanisms are genetically designed so that blood flow and oxygen to the heart are always protected. Thus, when the body of the M.E. (also known as Enteroviral Encephalomyelitis) patient is stressed, the blood flow to organs not necessary for short-term survival, such as the brain, the gut and skeletal muscles, can be temporarily decreased. This of course gives rise to many of the M.E. symptoms.

Gastroenterological, GIT Symptoms and Dysfunctions:

a. Pain, uncomfortable change of bowel habitus often occurs both at onset and in chronicity. 'Autoimmune bowel illnesses' have been seen. 

Crohn's Disease

Beware: M.E. (also known as Enteroviral Encephalomyelitis) patients may have unrelated GIT illnesses not associated with M.E. (also known as Enteroviral Encephalomyelitis) such as bowel malignancy and ulcers. The physician must be aware of more traditional illnesses.

e) Bowel Dysfunction: vascular dysfunction may be the most significant causal basis of the multiple bowel dysfunctions occurring in M.E. (also known as Enteroviral Encephalomyelitis) (See d. above.)

f) Ehlers-Danlos Syndromes Group: This is a group of illnesses with a genetic predisposition to M.E. (also known as Enteroviral Encephalomyelitis) or M.E.- like illness. In fact it probably represents a spectrum of illnesses that start with (i) hyper-reflexia syndrome, moving through any of the (ii) various Ehlers-Danlos Syndromes and climaxing in (iii) Marfan Syndrome where there tends to be early death if the aortic and cardiac changes are not repaired. Ehlers-Danlos Syndromes can go undetected until what appears to be a switch is turned on, usually in late teens to early thirties. The “switch” may be viral or possibly age or hormonal related. Raynaud’s Phenomenon is usually associated.

Diagnosis: briefly, patients over the age of 16 who can 

(i) Touch their nose with their tongue, 

(ii) Touch their forearm with the thumb of the same extremity (joint laxity), 

(iii) Touch the floor readily with the full palm should be considered suspect for further examination. There are several fascination variations of Ehlers-Danlos. They are generally considered to be a group of genetic illnesses but in my examination of M.E. (also known as Enteroviral Encephalomyelitis) patients most often are not manifested until well past puberty and in adulthood. Additional generalized features of this spectrum of illnesses include 

(v) India rubber or hyperelastic skin

(vi) Easy bruisability (vascular fragility)

(vii) Arachnodactyly (long spiderlike fingers). Many of the patients with a more severe form tend to be tall, slender with a dolichocephalic skull, high palate and long narrow feet with hammertoes verging on Marfan Syndrome(See Magalini, S. I., Magalini S. C. for both E-D Syndrome and Marfan 1 and Marfanoid hypermobility.)

g) Persantine Effect in M.E. (also known as Enteroviral Encephalomyelitis) Patients: Persantine is a chemical manufactured by Boehringer Ingelheim. It is employed to perform chemical cardiac stress testing when a patient cannot exercise sufficiently to stress the heart. It is a particularly safe medication but when employed with many M.E. (also known as Enteroviral Encephalomyelitis) patients it can cause severe muscle pain over the extremities and entire musculature. Normally this can be reversed by injection of an antidote but this does not always work rapidly in M.E. (also known as Enteroviral Encephalomyelitis) patients. Severe pain and fatigue can be intolerable and persist for minutes to days in some M.E. (also known as Enteroviral Encephalomyelitis) patients following Persantine use. Persantine works by dilating both peripheral and cardiac blood vessels and causing the heart rate to increase as in a PoTS patient. Obviously one major pain and fatigue factor in M.E. (also known as Enteroviral Encephalomyelitis) patients is caused by abnormal dilatation of peripheral blood vessels. The resulting pain may be related to reflex vasospasm as in severe Raynaud’s Phenomenon that I note elsewhere is one of the causes of M.E. (also known as Enteroviral Encephalomyelitis) pain. To my knowledge, no testing of M.E. (also known as Enteroviral Encephalomyelitis) patients with Persantine has ever been published by Boehringer Ingelheim or others. It is one of the reasons I believe that pain syndromes in M.E. (also known as Enteroviral Encephalomyelitis) patients are due to a pathological vascular physiology.

h) M.E. (also known as Enteroviral Encephalomyelitis) Associated Clotting DefectsM.E. (also known as Enteroviral Encephalomyelitis) represents both a vasculitis and a central and peripheral change in vascular physiology

All such vascular illnesses should be potentially treatable. 

We do not yet know how to adequately treat the 

(i) Genetic forms of vasculitis & vascular pathophysiology mentioned here, nor 

(ii) The probable viral triggered genetic vascular pathologies also mentioned. Nor do we know how to treat those 

(iii) Centrally caused injuries causing the circulating blood volume defects that are demonstrated when we do the “nuclear medicine circulating blood volume tests". 

It is important to do this test on all patients. 

PoTS is poorly treatable and more often success in treatment presently escapes physicians’ ability. Eventually, I have no doubt that these will be treatable causes of M.E.-like disease. 

However there is a significant group of M.E. (also known as Enteroviral Encephalomyelitis) patients who are ill due to a treatable form of vasculitis and can be treated if the physician takes the time to diagnose them. 

These patients are the clotting defect patients. Some of these clotting defects are genetic and some appear to be genetic with an age or viral switching mechanism, as I have mentioned elsewhere with Ehlers Danlos Syndromes; although they may develop in childhood, they are more frequently noted well after puberty and before the age of 40. 

Many of these patients can be diagnosed by the following tests: 

(1) Serum viscosity test

Hyperviscosity Syndrome

(2) Antiphospholipid Syndrome (Hughes Syndrome), 

(3) Protein C defects

(4) Protein S defects

(5) Factor V Leiden defect, to name the most common that we have uncovered. 

However, there are others for which we also test. These conditions are all potentially treatable and when treated adequately may allow the patient to return to school or work. Although any physician can order these tests, a haematologist should review all M.E. (also known as Enteroviral Encephalomyelitis) patients for these and other possible clotting anomalies. 

Most clotting defects are treatable and treatment has resulted in recovery in some cases. 

Remember M.E. (also known as Enteroviral Encephalomyelitis) is essentially a problem of microcirculation and any improvement in this area can have dramatically positive effects

It is well worthwhile for all physicians reading this definition who have an interest in M.E. (also known as Enteroviral Encephalomyelitis) to examine the Internet for Hughes Syndrome. Curiously, Hughes Syndrome was first outlined in St. Thomas’ Hospital London, the home of the Nightingale School of Nursing. Hughes Syndrome, a vascular syndrome also called Sticky Blood Syndrome, closely parallels the definition of M.E. (also known as Enteroviral Encephalomyelitis)

i) Anti-Smooth Muscle Antibodies: This is an antibody to the muscle tissue in the arterial bed. It is elevated in about 5% of M.E. (also known as Enteroviral Encephalomyelitis) patients but whether this is different in non-M.E. patients is unknown but unlikely. It rarely is over 1:40.

j) Cardiac Dysfunction: There are a large number of cardiac dysfunctions that can regularly appear in an M.E. (also known as Enteroviral Encephalomyelitis) patient

Certain are obvious and discussed under Ehlers-Danlos Syndrome and... 

...Marfan Syndrome

I also discussed cardiac dysfunction in Chapter 42, The Clinical and Scientific Basis of M.E. and CFS. 

Since that chapter was written a large number of other cardiac pathologies and pathophysiologies have been noted by various researchers and clinicians, particularly by Dr. Paul Cheney

Pericarditis







Without a clear understanding of these significant problem areas, it is simply indefensible and potentially dangerous to place an unsuspecting patient in a graduated exercise program. 

PACE trial

This is particularly true if the patient is not being tested in a cardiac unit. Although in our clinic we have performed what we believe to be a complete cardiac assessment on all patients seen, what the Ottawa Cardiac Institute and I believed was a complete assessment may be wanting. 

Over the next year we will reassess these patients, with a more detailed cardiac examination and report on it in these diagnostic criteria.

10. Testable Endocrine Dysfunction

These features are common and tend to be of late appearance. 

Would you recommend that M.E. Patients get their Thyroid checked up?

They are most obvious in:

24-Hour Holter Monitor for Arrhythmia (Irregular Heart Rates)

a) Pituitary-Thyroid Axis: Changes in serum TSH, FT3, FT4, Microsomal Ab., PTH, calcium and phosphorous rarely occur until several years after illness onset. This anomaly can best be followed by serial ultrasounds of the thyroid gland, where a steady shrinking of the thyroid gland may occur in some M.E. (also known as Enteroviral Encephalomyelitis) patients with or without the development of non-serum positive Hashimoto’s Thyroiditis (a seeming contradiction in terms)...

...and a significant increase in thyroid malignancy

Thyroid Cancer

What treatments would you recommend to an M.E. Patient with Thyroid Atrophy? 

Thyroid Ultrasound - measurements and size changes,...


...malignancy thyroid check with Ultrasound-guided fine needle aspiration (FNA) biopsy if abnormality suspected. 

Thyroid Biopsy

Fine-Needle Aspiration (FNA)

In cases of thyroid wastingserum positive changes tend to occur only after years and often not until the thyroid gland shrinks from the normal 13 to 21 cc. volume in an average adult female and 15-23 cc. volume in male patients to below a volume of 6 cc. (Mayo Clinic averages) (Rumack, Carol). The normal serum analysis of patients for thyroid dysfunction, TSH, FT4, microsomal antibodies etc., the golden rule of most physicians and endocrinologists, is simply not an adequate means of ascertaining thyroid dysfunction in most M.E. (also known as Enteroviral Encephalomyelitis) patients. Repeat thyroid ultrasound must be performed for all M.E. (also known as Enteroviral Encephalomyelitis) patients to observe the presence of dystrophic changes. It is also inadequate simply to accept the radiologist’s report of a normal thyroid. The volume of each lobe and it's homogenicity must be requested and documented. Radiologists simply report normal thyroids when in effect they are hypo and hyper-trophic. Although the Mayo Clinic averages cited above may be criticized they are as good as any in ascertaining normal thyroid size.

The following changes, while uncommon, may also be related to an M.E. (also known as Enteroviral Encephalomyelitisdisease process:

Hypothalamic Damage / Dysfunction and Tertiary Adrenal Insufficiency (Adrenal Dysfunction) as a consequence - Mount Sinai

b) Pituitary-Adrenal Axis Changes: where changes and findings are infrequent.

c) Pituitary-Ovarian Axis Changes

d) Neurogenic Bladder (Bladder Dysfunction) Changes: This dysfunction occurs frequently in the early and in chronic disease in some people. In some instances this may be due to a form of diabetes insipidus, in other cases it is related to PoTS-type illness where the patient is compensating for the inability to maintain vascular pressure by attempting to increase fluid volume. 

In other cases this may be due to interstitial cystitis...

...or a form of polio-type-bladder particularly if the cause of the individual disease is an enterovirus

Dr. John Richardson also associated this finding with adrenal dysfunction that he measured.

General Preamble: The proof of EV infection has previously always been difficult since there are over 100 different enteroviruses and often, E.V. tests are unavailable locally

E.V. infection can be identified by many ways
today, including:

The Dowsett, Ramsay, McCartney, Bell M.E. Study

The following data which defines the enteroviral origin and many of the major clinical aspects of M.E. (also known as Enteroviral Encephalomyelitis) was taken from a publication by Drs. E. Dowsett, A. M. Ramsay, R.A. McCartney and Eleanor J. Bell: published in the Postgraduate Medicine Journal (1990) Vol 66, 526-530. Note: This paper was published before modern SPECT brain imaging software was available in the U.K. demonstrating major and hypo-perfusion specific brain injures in M.E. (also known as Enteroviral Encephalomyelitis) patients. Today, due to the development of better brain SPECT imaging with Segami Oasis software, we know a great deal more than was published in the never-the-less very accurate, but incomplete clinical description of M.E. (also known as Enteroviral Encephalomyelitis) in this 1990 paper. As you see, this description of M.E. (also known as Enteroviral Encephalomyelitis) in no way resembles any of the CFS criterias. That is because it was based upon knowledgeable experts and real epidemiological studies of patients with a known enteroviral-causal link with M.E. (also known as Enteroviral Encephalomyelitis). This publication clearly defines M.E. (also known as Enteroviral Encephalomyelitisas a neurological disease caused by a large group of Polio-like causing enteroviruses that today are also increasingly causing the New Polio (AFM), paralysis and death. Dr. Eleanor Bell of Ruchill Hospital, Glasgow, and her associates investigated 420 patients with M.E. (also known as Enteroviral Encephalomyelitiswho had fallen ill following an acute infection with either Coxsackie enteroviruses and/or other enteroviruses. This study demonstrates that M.E. (also known as Enteroviral Encephalomyelitisis an enteroviral disease following a varied number of enteroviruses

Their patient clinical findings are outlined and are divided into (a) neurological findings and (b) other muscular skeletal, (c) gastrointestinal, (d) rheumatologic-like, (e) hormonal, (f) cardiac and (g) vascular injuries. All these findings were obviously missed in 1990, a time when Dr. Bell et al did not have the advantage of our investigational ability in Canada, USA and Chile, where their findings have been corroborated and even more detailed finding have been demonstrated: 


It is obvious from Drs. Dowsett, Ramsay, McCartney and Bell’s publication in Postgrad Medicine Journal that M.E. (also known as Enteroviral Encephalomyelitisis a (1) a post enteroviral, (2) acute onset, (3) neurological injury, and (4) a total body injury. This was obviously missed by the CDC and NIH studies in their various faulty stabs at understanding M.E. (also known as Enteroviral Encephalomyelitisin the Incline Village epidemic in 1984 and elsewhere. I have kept the content of the Dowsett table and reorganized it into neurological and a largely non-neurological section. Although in the case of Myalgia, it is difficult to know where the neurological system begins and ends without proper neurological tests. 

Four of the findings in the 420 M.E. patients, which I have placed in the non-neurological section could equally be placed in both columns and they are: 

1. Muscle Dysfunction: Probably caused in part by brain mediated fall in the circulating blood volume, which in our studies routinely fell to 40% of normal on nuclear testing. Muscle fibre testing can routinely demonstrate single muscle fibre “jitter, which may be missed on routine nerve conduction tests

2. Reactive Changes: Noted at 98%: There is certainly physiological depression seen in most brain injured patients and the frustration related not being able to accomplish normal neurological and intellectual tasks. Anyone without reactive changes with M.E. (also known as Enteroviral Encephalomyelitismust have the constitution of an ox. This is understandable since at acute onset, many patients have such overriding, severe symptoms and weakness they believe they are about to die. Meanwhile they are being told nothing is wrong and all the tests are normal, (because no specific correct tests have been ordered

3. Urinary and or Vaginal Disturbance: Noted at 38%: This, as in interstitial cystitis, is regularly observed in female paralytic Polio, and M.E. (also known as Enteroviral Encephalomyelitispatients. 

4. Thyroiditis 5%: If this is changed to Thyroid Disease the figures might have been much larger. I have regularly noted thyroid abnormality in up to 50% of M.E. (also known as Enteroviral Encephalomyelitisfemale patients. This may be because I also do thyroid ultrasound, where I commonly find thyroid volume change, and thyroid nodules. Thyroid shrinkage or enlargement is not observed if only blood tests are ordered. I also inspect for Thyroglobulin and thyroglobulin antibodies, which can demonstrate autoimmune thyroid disease

Dowsett et al. also found abnormal EEG but her group were not knowledgeable of the later findings of (1) grossly abnormal Brain SPECTs, (2) positive recovery of enteroviruses from the spinal fluid, (3) increased spinal fluid pressure at onset, (4) dramatic fall in circulating blood fluid as low as 40% of normal, and (5) often oligoclonal banding in first 1-2 weeks of M.E (also known as Enteroviral Encephalomyelitisillness. 



For patients with a persistent Non-Cytolytic Enterovirus infection

GP PAGE

DIAGNOSIS: When a patient presents with an infectious disease which does not clear within 14 days - 28 days and the main symptom is Fatigue with Post-Exertional Malaise (PEM)


Serology should also be performed for EBV, Enterovirus, Coronavirus and Borrelia 

INVESTIGATIONS 

1. At onset [within first 4 weeks]Viral serology including Elisa IgM for Enteroviruses
Auto-immune screenCRP or Esr - Standard blood test [FBC, LFTs, U&Es etc]
2. fMRI or SPECT hypoperfusion brain scans if able; or at referral.
3. Other investigations are same as those for research inclusion.

To wait for 6 months before treatment is in breach of the Hippocratic Oath. 

Treatment should commence as soon as possible.

TREATMENT

1. It is a proven scientific fact that Enteroviruses replicate because they possess an Activity Sense Switch and an Internal Ribosome Entry Site; resulting in Robbing cell Peter to pay virus Paul

The end result of which is a sick cell, potentially sick organ[s] and extremely sick patient. It is common sense therefore to rest the patient and only adopt a flexible activity regime when the patient has little or no Post-Exertional Malaise (PEM)

Because the patient is naturally well motivated and energetic, strict self discipline is required.

2. Immunoglobulin i.m. injections to modulate the immune system in favour of the patient. 

The John Richardson Research Group has used this treatment for the past 30 years with energy levels increasing over time from 20% up to 80% with Persistent Non-Cytolytic Enterovirus Infection. 

Also heart and autoimmune sequellae have been minimized. Unfortunately, the proponents of the misnomer CFS have prevented genuine research into this treatment of M.E. (also known as Enteroviral Encephalomyelitisfor at least 30 years.


4. Similarly patients should avoid any drugs which suppress their immune/virus balance in 
favour of the virus. E.g. Intravenous Steroids, Rituximab or Etanercept

5. Nor should patients be exposed to unnecessary stress which, as with the above, suppresses their immune system; causing deterioration of their illness. 

An Esr or CRP together with a full Autoimmune Screen should be monitored annually as 20% of patients develop auto-antibodies; particularly thyroid.

Abstract

Introduction

The majority of enterovirus infection in pediatrics presented with Hand, Foot, Mouth & Disease (HFMD) and oral ulcers. A few of these patients had manifestations of polio-like encephalitis 





Aim of the work

The aim of our study was to highlight the MR imaging features of enterovirus infection of the brain and spinal cord.

Patients

25 patients with Hand, Foot, Mouth & Disease (HFMD) and clinical diagnosis of encephalitis were included in this study.







Methods

It is a retrospective study with respect to the confidentiality of the medical record. The patients were exposed to MR imaging with T1WI images pre and post contrast, and T2WI MR images, FLAIR, susceptibility weighted imaging (SWI), and diffusion weighted imaging (DWI) were obtained in all patients. Enterovirus culture confirmation was available in some cases.

Results

MR imaging of the 25 patients revealed 5 patients with normal MRI brain examination. T2 hyperintensity within the brainstem was seen in 16 patients, while 2 patients showed cervical cord lesions and two patients with dentate nuclei lesions.

Conclusion

Enterovirus encephalomyelitis has characteristic lesion locations in the posterior portions of the brainstemsubstantia nigra, dentate nucleus and within the anterior horns of spinal cord. Recognition of these findings in the presence of suggestive clinical presentation can help to establish the diagnosis of enterovirus encephalomyelitis.

English


Functional Brain Mapping with HMPAO SPECT & Segami Oasis NeuroGam software

The following M.E. (also known as Enteroviral Encephalomyelitispatient brain map is a Tc99m-HMPAO brain perfusion SPECT obtained with NeuroGam software by Dr. Sonia Neubauer, Clinica Las Condes, Santiago, Chile on a classical M.E. (also known as Enteroviral Encephalomyelitispatient of Dr. Byron Hyde. This OASIS software was developed by Dr. Ismael Mena & Segami Corp., USA, in comparison with age-related, healthy, drug, alcohol, tobacco, caffeine free controls.

SPECT brain scans of Canadian & USA patients were performed by Dr. Neubauer in Chile, some by Dr. Marc Freeman at Mount Sinai and Mississauga Hospitals in Toronto and Dr. Jean Leveille in Sorel Quebec and the DICOM data sent to Dr. Neubauer to obtain the 3D normal database comparison brain maps. The following is the brain map of a typical, significantly injured M.E. (also known as Enteroviral Encephalomyelitispatient.


Note: In the 3D SPECT brain map above, colour coding documents the standard deviations of hypoperfusion below normal. The gray field is the normal perfusion within 2 standard deviations of the mean: blue: minus 2; dark blue: minus 3; green: minus 4 standard deviations of hypoperfusion below normal. Decreased perfusion represents progressively decreased vascularization & cognitive function. Two day, post-physical or post-intellectual activity scans show further decreased SPECT brain perfusion & associated CNS disabilities consistent with patients’ complaints.

The above M.E. (also known as Enteroviral Encephalomyelitisbrain SPECT demonstrates significant 3 and 4 standard deviations hypoperfusion injury of:

a. the temporal lobes, including Brodmann’s areas 38 and 22, more marked on the left side, one of the brain’s primary intellectual control, receiving and transmitting centres.



d. the operculum area covering the insular cortex. The Insula plays an essential role in homeostatic functions. In our experience, this area is always hypo-perfused in M.E. (also known as Enteroviral Encephalomyelitispatients with autonomic dysfunctions (& PoTS). The physician is mistaken if he believes exercise, CBT, GET or PACE theory will help insular injury patients. Nor does it help the patient to stay forever in bed due to fear. Depending upon the patient’s severity of illness, a gradual, patient regulated increase in activity is more favourable, both for the body and the soul, in an ideal world. 

We do not live in an ideal world. It can be dangerous in those still infected with the virus or can increase the severity of their disability in those attempting to push past their physiological and biological limits. 

(Not so possible in the most severe patients, or if the virus(es) is, or are still present, without antivirals or greater immune regulation, to favour the patient, exercise promotes "viral replication" in chronically infected patients, increasing the severity of their sickness/illness or potential disability)

SPECT hypoperfusion findings are variable in each patient but consistent with their symptoms. The most disabled M.E. (also known as Enteroviral Encephalomyelitispatients demonstrated the most severe bilateral brain SPECT functional abnormalities. All patients with significant muscle dysfunction had hypoperfusion in the motor cortex, (Brodmann’s 4 of the posterior frontal lobe). EV infection causing localized myositis has also been demonstrated. (Leonard C. Archard)

Severity of the M.E. (also known as Enteroviral Encephalomyelitis)

a. As in all diseases, M.E. (also known as Enteroviral Encephalomyelitispatients differ as to severity.

b. The severity of the disease-state is in part directly related to the increasing degree & extent of bilateral involvement of the brain,

c. Patients with Dysautonomia and/or PoTS dysfunctions invariably demonstrated hypoperfusion in the operculum area overlying the insular cortex as in the above patient, suggesting an insular cortex injury in our 
dysautonomia patients.

d. Patients with pre-existing or newly-discovered :


(b) Collagen diseases, and those who have fallen ill immediately (within hours or 7 days) upon receiving 

(c) Recombinant Hepatitis B immunization are among the most disabled patients we have seen.

e. Deaths have occurred during epidemics & infrequently in sporadic cases.




Discussion of Physiological Changes in this 
Brain Perfusion SPECT

a. Anterior Temporal Lobe Injury: hypoperfusion involving the left anterior temporal pole (Brodmann 38). It is these temporal (& cingulate) lobe injuries that both define & explain many M.E. (also known as Enteroviral Encephalomyelitisdisabilities. 

The anterior temporal area is the major brain area responsible for retrieving & processing all intellectual & memory data, including:

(a) information-gathering from memory storage banks in the cerebrum

(b) all visual & auditory information & memory transmission, learning & processing from the brain & certain external receptors, pass through this essential information center of the brain

(c) speech comprehension, naming of items, word retrieval, voice identification, 

(d) humour, irony, music appreciation is mediated through this and the posterior temporal region. 

When the left temporal lobe is injured there is a disruption of learning, data transfer and cognition. In all of our M.E. (also known as Enteroviral Encephalomyelitispatients, the temporal lobe is always injured. Data retreived in Brodmann 38 is processed through the 
posterior cingulate gyrus. Overriding these defects is possible but severely energy-costly. It is our belief that only at great energy expenditure can the patient, for short periods, override these physiological deficits. 

However, this increased energy expenditure is the cause of temporary or long-term exhaustion, typical of the M.E. (also known as Enteroviral Encephalomyelitispatient.

b. Insular Cortex Injury: In this patient’s brain map, there is hypoperfusion of the operculum, (the anterior sylvian fissure area of the temporal, frontal and parietal lobe junction). (The operculum overlies the insular cortex.) The insular lobe is a major area responsible for homeostasis and other autonomic, sympathetic and parasympathetic nervous system functions including heart and vascular regulation. This may be the CNS area largely responsible for much of the vascular and autonomic dysfunction of M.E. (also known as Enteroviral Encephalomyelitispatients. In our experience, PoTS and cardiovascular irregularity are typical findings in some significantly injured M.E. (also known as Enteroviral Encephalomyelitis) patients. They consistently have severe hypoperfusion in the operculum area.

c. The Cingulate Lobe of the Limbic System: There is significant hypoperfusion of the left posterior cingulate gyrus (Brodmann 23, 31), 
as well as the left anterior cingulate lobe (Brodmann area 33, 24) of the limbic system in this and all M.E. (also known as Enteroviral Encephalomyelitispatients. However, in this patient there is also hypoperfusion in both left and right cingulate (limbic system).

The posterior cingulate is an area involving learning, memory retrieval, recall, learning complex motor skills, visual processing, emotions, consciousness, sleep and alertness functions. The posterior cingulate, in our experience, is directly related to the anterior temporal lobe (Brodmann 38) discussed above. It is believed to be an important area in regulating important cognitive data and retrieving autobiographical informationThe anterior cingulate (Brodmann 33, 24) shares many of the same intellectual and memory tasks as the posterior cingulate but also pain endurance, visuospatial attention, multi-tasking, and auditory attentionThere is generally injury in both cingulate areas.

d. Although significant hypoperfusion is always present in the left temporal and cingulate lobes of the limbic system in M.E. (also known as Enteroviral Encephalomyelitispatients as noted by Goldstein* in 1990, in this severely disabled M.E. (also known as Enteroviral Encephalomyelitispatient there is bilateral cingulate hypoperfusion. In addition there is hypoperfusion of the left motor cortex. (Brodmann 4)







Other Laboratory Findings Found in M.E. (also known as Enteroviral Encephalomyelitis: 

The following laboratory findings give understanding to the noted first and second phase illness but are not always found. Findings can vary depending upon the time after illness when the tests were taken. The following findings are not essential in making the laboratory diagnosis of M.E. (also known as Enteroviral Encephalomyelitisbut support a disability diagnosis.

a. Lumbar Puncture: Positive oligoclonal banding & increased pressure & leukocytosis in first weeks. (Poser) (Suggesting CNS neuronal injury). This requires a lumbar puncture and is rarely done since the physicians tend to mistake the initial weeks of illness as a transitory influenza-like illness. (A small gauge needle must be used due to potential increased spinal fluid pressure.)

b. SPECT: Basal ganglia hypoperfusion injuries. These findings can be seen in early & ongoing persisting chronic illness. (Mena; Hyde). Two of our M.E. (also known as Enteroviral Encephalomyelitispatients have gone on to develop Parkinson’s disease which may be co-incidental, but this also occurred three years later in children, who then died as a result of the Akureyri M.E. (also known as Enteroviral Encephalomyelitisepidemic in Iceland.

c. Decrease in number and activity of Natural Killer Cells in early weeks of illness.

General Treatment Advice

In any disease or illness, all effective treatments depend upon an indisputable, reproducible scientific diagnoses. This booklet provides these criteria. This definition allows research scientists and pharmaceutical companies to research effective treatment modalities.

The various broad symptom-based CFS criterias are all non-specific and common to many chronic illnesses. There have been over 50 treatments suggested for CFS since it appeared as a working case diagnosis in 1988. The sheer number is a clear indication that there is no effective treatment for any of the various CFS diseases. Some of the many CFS diseases are treatable if the diagnostic cause is found. CFS is not a disease. It is many different and sometimes treatable diseases.

Clues to Diagnosis:

1. Proof of an enteroviral infection.

2. In the north-temperate latitudes, M.E. (also known as Enteroviral Encephalomyelitis& enteroviral infections tend to begin in late summer and early autumn.

3. At least two thirds of the patients tend to be women.

4. Students, teachers and health care workers are among the most common groups injured.

5. Immediate post immunization illness (within one week) can be a trigger. Immunizations decrease immune response for 1-3 weeks, particularly if they are already infected or leaving on a trip to a third world country.


Unlike M.E. (enteroviral encephalomyelitis), EBV infectious mononucleosis has a longer incubation period (around 4-6 weeks), no seasonal pattern, and a characteristic clinical profile:

1. Clinical Features: fever, marked fatigue, exudative pharyngitis with tonsillar enlargement, and prominent posterior cervical lymphadenopathy. Splenomegaly is common; hepatomegaly or mild hepatitis may occur. Palatal petechiae and periorbital edema are sometimes seen.

2. Blood Findings: lymphocytosis with numerous atypical (reactive) lymphocytes. This picture can resemble hematologic malignancy, especially acute lymphoblastic leukemia (ALL) or other acute leukemias, because of the abnormal-appearing lymphoid cells and systemic features. The distinction rests on cell morphology (reactive lymphocytes are heterogeneous; blasts in leukemia are monotonous), serology, and if needed, flow cytometry.

3. Rash: Appears spontaneously in ~5-15% of cases as a morbilliform or maculopapular exanthem. Occurs in up to 70-95% of patients who receive aminopenicillins (e.g., amoxicillin/ampicillin) during acute infection. This eruption is a virus-drug interaction hypersensitivity rash, not a true penicillin allergy.

4. Course/outcomes: Adolescents and young adults usually recover within 2-4 weeks, though fatigue may persist for weeks to months. Severe complications (airway obstruction, splenic rupture, hemolytic anemia, thrombocytopenia, encephalitis) are uncommon. Death is rare, but immunocompromised patients may be at higher risk.

Summary: EBV infectious mononucleosis is distinct from M.E. (also known as Enteroviral Encephalomyelitis), both in cause and presentation. It's hallmark is lymphoid proliferation with a leukemia-like blood picture, NOT the neurotropism seen in enteroviral encephalomyelitis.


A minority of patients who develop infectious mononucleosis from Epstein-Barr virus (EBV) remain chronically unwell beyond the expected recovery period. In prospective studies, about 10-12% still meet criteria for a post-viral fatigue syndrome at six months


The persistence appears to be driven not by direct neuronal injury, but by immune dysregulation - prolonged activation of cytotoxic T cells, elevated cytokines, possible intermittent EBV reactivation in B cells - coupled with autonomic imbalance and metabolic inefficiency

This explains the overlap with SEID criteria: exertion worsens symptoms because immune and autonomic systems remain sensitized.

Unlike M.E. (Enteroviral Encephalomyelitis), which is an encephalitic process with direct neuronal involvement, EBV-related post-viral fatigue is primarily a systemic and immunological aftermath. Clinically, EBV mono presents acutely, but the fatigue syndrome that follows is typically subacute, emerging as the infection resolves. Some patients gradually improve, while a subset remain symptomatic for years, though without the structural CNS injury characteristic of M.E. (also known as Enteroviral Encephalomyelitis).


Acute phase: mono itself is an acute illness, with fever, pharyngitis, lymphadenopathy, and fatigue lasting weeks.

Subacute transition: instead of fully recovering, some patients notice that fatigue, cognitive fog, and exercise intolerance persist beyond the clearance of acute symptoms.

Gradual evolution: in this group, the post-viral fatigue picture emerges gradually during convalescence - they don’t suddenly collapse into illness after recovery, but rather fail to return to baseline and often plateau at a chronically impaired level.

Chronic course: a subset remain symptomatic for months to years, fulfilling SEID criteria (PEM, unrefreshing sleep, cognitive dysfunction, orthostatic intolerance).


By contrast, M.E. (also known as Enteroviral Encephalomyelitisis typically abrupt in onset - often within days of a flu-like illness or during an epidemic outbreak.

Patients describe a sudden loss of capacity linked to neurotropic injury (encephalomyelitis), rather than a slow or incomplete recovery.

✅ So:

EBV PVFS develops subacutely to gradually as an incomplete recovery after an acute mono illness.

M.E. (also known as Enteroviral Encephalomyelitisdevelops acutely, in direct association with enteroviral CNS infection.

M.E. (also known as Enteroviral Encephalomyelitisas a Polio Analog

Ivar Wickman, in his 1905 epidemiological study of the Stockholm poliomyelitis epidemic, described not only spinal and bulbar polio but also a form he termed “superior polio” - where the brain itself was the main target rather than the spinal cord

This clinical picture is strikingly similar to what would later be called Epidemic Myalgic Encephalomyelitis (M.E.(also known as Enteroviral Encephalomyelitis).

In classical Spinal and Bulbar Poliomyelitis, Paralysis and Death occur because Poliovirus invades and destroys Anterior Horn Motor Neurons (and in bulbar cases, cranial motor nuclei). Once these neurons are lost, muscles are permanently denervated and Paralysis is irreversible.

In M.E. (Enteroviral Encephalomyelitis), the predominant injury involves Cortical, Brainstem, Autonomic, and Motor Control regions above the spinal cord. This leads to profound Motor Weakness, pathological Muscle Fatigability, Cognitive Impairment, and Central Nervous System Dysfunction, often accompanied by Dysautonomia, including Postural orthostatic Tachycardia Syndrome (PoTS). In some cases, the Anterior Horn Cells of the spinal cord are also affected, producing episodes of Flaccid Paralysis. However, unlike "classical" Poliomyelitis where Anterior Horn Cell Destruction frequently causes Permanent Paralysis, in M.E. (also known as Enteroviral Encephalomyelitisthis outcome is much less common and may be entirely absent. For this reason, M.E. (also known as Enteroviral Encephalomyelitisis best regarded as analogous to the Non-Paralytic or Encephalitic forms of Poliomyelitis historically recognized, rather than to the "classical" Paralytic form.

Because Enteroviruses are Neurotropic, Poliomyelitis-like Syndromes and Encephalomyelitis can co-exist within the same infection. Patients may therefore present with a combination of Acute Flaccid Paralysis from Anterior Horn Involvement and Encephalitic features such as Cognitive Disturbance, Dysautonomia, or Brainstem Dysfunction.

Although Poliovirus is the archetype, other Enteroviruses are well documented to cause Poliomyelitis-like Flaccid Paralysis - including Coxsackie B viruses, Enterovirus A71, Enterovirus D68, and Enterovirus A7. These infections can produce isolated spinal cord syndromes, Encephalomyelitis, or mixed presentations that overlap both Polio and M.E. (also known as Enteroviral Encephalomyelitis)

Acute vs. Chronic Presentations:

Poliomyelitis-like Syndromes are acute illnesses, producing Flaccid Paralysis when Anterior Horn Cells are injured or destroyed. M.E. (also known as Enteroviral Encephalomyelitis), by contrast, is a Chronic Encephalitic Illness marked primarily by persistent CNS Dysfunction. While Flaccid Paralysis may occur in M.E. (also known as Enteroviral Encephalomyelitis), permanent Paralysis is uncommon to absent, distinguishing it from classical "Paralytic Polio".

Specific Anti-Enterovirus Antiviral Medications:

Because enteroviruses can both impair and destroy neurons depending on the strain, viral load, and host response, outcomes vary from reversible dysfunction to permanent paralysis. In some cases of encephalomyelitis, neurons survive but remain chronically impaired, meaning antiviral therapy could help preserve or restore function. In paralytic cases, where motor neurons are lost (as in poliomyelitis or AFM), recovery is limited, but antivirals could still prevent further injury if given early. Several candidate anti-enteroviral agents - including pleconaril, vapendavir, pocapavir, and rupintrivir - have shown promise in laboratory and animal models, though none are yet standard of care.

Protect the Patient:

1. Immediate short-term disability pensions if available must be provided. Stress makes M.E (also known as Enteroviral Encephalomyelitisillness physiologically worse and retards any recovery, if any recovery is to occur. A general, non-specific enterovirus immunization would prevent M.E. (also known as Enteroviral Encephalomyelitis)

Enteroviral Findings for the Period 1980-1990

An ongoing M.E. (also known as Enteroviral Encephalomyelitisepidemic, of chronic post-infectious disease, occurred across the USA and Canada that became apparent in the late summer and autumn of 1984 and continued on until the early 1990's. The Lake Tahoe epidemic was a typical enterovirus provoked illness that occurred in 1984.

The cause of the epidemic in Ontario was recorded by the Ontario Government Health Services as seen in the above graph. A variation of this graph was first published in the 1992 publication, The Clinical and Scientific Basis of M.E. and CFS. There was no increased activity of EBV-generated mononucleosis or fatigue syndrome during this period.

The Personal Computer Revolution: What became very different about this severe and disabling epidemic, was the knowledge of its presence was taken out of the hands of the American National Institute of Health, and Centers for Disease Control and Health Canada by the rise of the personal computer that allowed the disabled individuals and their families to communicate the presence of this illness to the world. These disabled individuals have not gone away. In effect, this is the chart of the continental North American M.E. epidemic that struck Lake Tahoe, North Carolina Symphony, Lyndonville, New York State and the various Canadian and European M.E. epidemics. It would appear that the various North American epidemics from 1984 are all enteroviral based epidemics.

Beginning in 1984 and extending into the 1990's, the Nightingale Research Foundation took quarterly blood samples of over 70 disabled individuals with post-infectious M.E (also known as Enteroviral Encephalomyelitisalong with about 30 controls. My daughter and I carried these samples to the Ruchill Hospital in Glasgow Scotland, where they were examined by the virologists Drs. Daniel Galbraith and Carron Nain.

Ruchill was then the viral investigation laboratory for all of Scotland and was run by the senior virologist, the late Dr. Eleanor Bell. The above tree is consistent with the findings of the Ontario Government Health Services except where the Ontario Government was able to identify the E.V.s. in this epidemic, but not always the subtype. Ruchill was able to identify a significant number of E.V. subtypes as noted in this tree from 20 different Canadian and US patient samples.

On the basis of this study we were able to conclude that many different enteroviruses are capable of causing M.E. (also known as Enteroviral Encephalomyelitis).

No other active viruses were noted.



We chose the Tiger, a natural killer, as our logo because one of the first scientific benchmarks of M.E. (also known as Enteroviral Encephalomyelitisand Lake Tahoe CFS was the fact that patients lacked active natural killer cells, an essential part of the immune system

We chose Nightingale as our name in honour of Florence Nightingale who fell ill with an infectious disease believed to have been Brucellosis during her service in the Crimean War. Despite her severe disability, she went on to reform both public health and health care, helping to bring medicine and especially the care and treatment of the ill patient into the Twentieth Century.
