Cognitive impairment also called “brain fog” is present in up to 85% of the patients with ME/CFS; for some patients, it is the most debilitating symptom. The cognitive impairments occur in the domains of attention, Information processing, memory, and reaction time, functions restricted in the limbic system (LS). Besides ME/CFS, HSV1 encephalitis, Alzheimer’s dementia (AD) and limbic encephalitis (LE) also affect the same areas of the brain. Recent findings from our group, demonstrated HSV1 and CMV Infection are associated with severe ME/CFS. In addition, HSV1 is also correlated with encephalitis, AD, and LE.Furthermore, the APOE ε4 allele is the stronger genetic marker associated with the AD. APOE ε4 allele and the HSV1 infection are the most prevalent risk factors for the development of late-onset AD.

The overlapping in clinical manifestations, imaging studies, HSV1 Infection and histopathological changes between ME/CFS and AD, raise the probability of the APOE ε4 alleles as a connector between ME/CFS and AD.

A cross-sectional, IRB approved study with 300 patients enrolled (150 adults with ME/CFS and 150 no ME/CFS controls) will be completed at Stanford University. The participants will be enrolled from the Stanford ME/CFS clinic. We will collect, demographics, clinical and laboratory data, and MFl-20 score, as a determinant of severity of Illness.

Blood draw samples for analysis and determination of APOE genes (ε2, ε3, and ε4). The aims of this study will include:

Evaluation of the prevalence of ε4 alleles (homozygous and heterozygous) in the patient with ME/CFS and compare with healthy no ME/CSF as negative controls

Establish the correlation of the ε4 alleles (homozygous and heterozygous) with the severity in patients with ME/CFS

Association of ε4 alleles in patients ME/CFS and positive herpes serology (HSV-1 and CMV) serology.”

Whaaaat? A new researcher? That can't be right?

Nobody new would brave this field would they?

I heard (from a super reliable source) that they were all running away screaming from angry ME hordes.

OK I'm done now.
now back to the study . . .

No need for that level of dramatics when all they need to do is stand there for a while and the hordes of PwME will either collapse or forget why they are there, or maybe both.

Reality may not make such 'good' headlines.
