1/ The problem with Myalgic Encephalomyeltis/Chronic Fatigue Syndrome #MECFS is that it seems so ridiculous that exercise could actually make patients worse

How can exercise be so bad for #pwME but so good for almost every other serious illness?

THREAD 2/ New study by @4WorkWell @sunsopeningband et al shows that #MECFS patients have metabolic defects that cannot be explained by exercise phobias, deconditioning or 'illness beliefs'

#pwME have reduced oxygen consumption during exercise tests

1/ How neglected is Myalgic Encephalomyelitis/Chronic Fatigue Syndrome research?

@NIH funding for ME/CFS in 2017 was ~$25mill

Fair funding relative to disease burden should be ~$350mill

That means #MECFS research was short-changed by $325,000,000 (14-fold!) in just ONE YEAR 2/ Buckle up!

@CenterRes analysis found that even though the disease burden of #MECFS was double that of HIV/AIDS, #AIDS research received ~$5billion in 2017

Thats a 20-fold shortfall, amounting to ~$4,975,000,000 lost #MECFS funding in just ONE YEAR!

Thread: #SARS_COV_2 infects the brain

@NEJM study found >50% of #COVID19 patients had neurologic involvement including encephalopathy, agitation, confusion & corticospinal tract abnormalities

Immune activation in the cerebral spinal fluid was observed
nejm.org/doi/full/10.10… 2/ #SarsCov2 can infect the brain and muscle

This @jama study found that patients with severe #COVID19 were more likely to have neurologic symptoms including acute cerebrovascular disruptions, impaired consciousness, and skeletal muscle injury

Thread:

12 reasons that <some> doctors disbelieve patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome #MECFS

1. Doctors tended to see #pwME as having “certain personality traits"

#SickNotWeak #MedEd #MedicalTwitter
bmj.com/content/328/74… 2. Doctors felt that #MyalgicE lacks a plausible pathological mechanism and its symptoms couldn't be ascribed to a precise location

3. There has been variation in the diagnostic criteria for #MECFS which has delegitimised the disease

1/ The Australian Fed government is using #COVID19Aus ‘mitigation’ modelling which permit ‘controlled burns’ of #SARSCoV2 through the population resulting in unnecessary deaths

doherty.edu.au/uploads/conten… 2/ Current federal government #COVID19Aus policy is based on 'mitigation' modelling where the #coronavirusaustralia is allowed to spread with a reproductive number R0 of >1.0 which would allow 10s-of-1000s of unnecessary Australian deaths

The insightful questions below come from this nice @diagnostic_mdpi review

mdpi.com/2075-4418/9/3/… 1. Is there a genetic susceptibility which leaves some individuals vulnerable to #MECFS after exposure to a virus, bacteria or toxic chemical?

Thread:

#MECFS patients face disbelief that they are sick

Many #MECFS patients are told that they are simply tired, stressed, anxious, depressed, lazy or malingering

How can #pwME respond to such disbelief and lack of understanding??????

See thread below: 2. Below are 7 evidence-based scientifically supported findings that you can use to inform those who dont understand that #MECFS is a multi-organ, systemic and severely debilitating illness

Thread. Medical Hysteria and #InternationalWomensDay

In 1882, Anna O is considered 'patient zero' for the diagnosis of "Hysteria"

#Hysteria was originally a diagnosis only given to women

Anna O fell ill in 1880 after her father died, possibly of Tuberculosis 2. Her symptoms: severe 'nervous' #cough, paralysis, numbness, vision/hearing/speech disturbances, hallucinations, #cognitive difficulties

She was diagnosed with "Hysteria" by Breuer and Freud in ~1882
