A new paper came out about glutamate, #MECFS, & #LongCovid.



It made me realize that it's been almost a year since @KatBoniface's epic glutamate thread!

She had come across it when looking into the Default Mode Network & Amoxiclav.

#MeLcFladLisbon Similar cortisol profile in severe ME and LC. morning lower than controls

Klein 2023 - also found lower cortisol

Su 2022 - PASC lower than controls

#MeLcFladLisbon I'm not an expert, not a clinician, not a patient. I'm a journalist who has reported on #MECFS and #LongCovid.

Early 2020 people thought Covid sent you to the hospital or was mild. Then people started to talk about not recovering. When I interviewed scientists and clinicians in May many were surprised

Talk 5 - Lucinda Bateman (presenting via video)

Covid Long haulers, Presentation of Long COVID and Post-Viral Syndromes, Common Comorbidities of Long COVID and the Design of Simple Treatment Plans

The Nexus Between ME/CFS and Long Covid: Insights from the NIH RECOVER Initiative and the NIH ME/CFS and Long COVID Commonalities Task Force

#MeLcFladLisbon Mission is to tell about project that was offshoot of RECOVER, effort to determine commonalities between #MECFS and #LongCovid. His specialty exercise pathophysiology

Systemic circulatory abnormalities

Skeletal muscle mitochondrial dysfunction (worthy of Dx and Tx)

I'm working on a thread about the overlap between #MECFS & post-spaceflight physiology in 👩🏿‍🚀🧑🏾‍🚀 w/@cstroeckw & @cuboidalhug

I'm going to use this thread to gather references. Please share any you have, especially for dysautonomia & viral reactivation! @RayCronise, any tips or contacts?

#MECFSroadmap nervous system talk 2. Gudrun Lange on Cognitive Function

"Cognitive dysfunction is one of the most frequent and disabling symptoms of #MECFS"

"89% of patients perceive memory & concentration problems" "Cognitive dysfunction in #MECFS is independent from depressive disorder, though depressive disorder can be comorbid"

"Reported relation to lack of effort/motivation is not supported by data"

"They are REAL."

Normally look into peripheral circulation, but it's connected with tissue
