Except it may not be damage. (In the same way T cell subset exhaustion markers do not mean globally tired T-cells.) The changes in diffusivity might not indicate neuroinflammation or cell damage. It could relate to myelin maintenance and even be compensatory, ie increased or decreased to...

Etymology: "to flood back". See aortic/mitral/pulmonary/tricuspid valve regurgitation.

Published in July — Distinct white matter alteration patterns in post-infectious and gradual onset chronic fatigue syndrome revealed by diffusion MRI While post-infectious (PI-ME/CFS) and gradual onset (GO-ME/CFS) myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) manifest similar...

Missed this one at the beginning of last year, but it was referenced in Interrogating pulmonary diffusing capacity in long COVID: insights from DLCO and DLNO testing (2025)

Symptomatic post COVID patients have impaired alveolar capillary membrane function and high VE/VCO2 BACKGROUND Post COVID-19 syndrome is characterized by several cardiorespiratory symptoms but the origin of patients reported symptomatology is still unclear. METHODS Consecutive post COVID-19...

Hold up. I thought we were paying too much attention to bodily symptoms?

Safety and Effectiveness of an Exercise-Based Telerehabilitation Program in Myalgic Encephalomyelitis and Post COVID Syndrome: Protocol for a Randomized Controlled Clinical Trial BACKGROUND/OBJECTIVES Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and Post-COVID Syndrome (PCS) are...

It's CSF flow during the cardiac cycle through the cerebral aqueduct (between third and fourth ventricles). It goes 3 → 4 in systole with a bit of regurgitant/retrograde flow 4 → 3 in diastole. I've annotated a screengrab from Green marks the aqueduct. Red arrow shows direction of the larger...

Inflammation from mild COVID-19 results in persistent neurological and behavioral changes in rhesus macaques Although most SARS-CoV-2 infections result in mild or moderate symptoms not requiring hospitalization, many patients experience persistent symptoms after their initial recovery, a...

Blood pro-thrombotic analytes and platelet activation are associated with post-acute sequelae of COVID-19 Post-Acute Sequelae of COVID-19 (PASC), or “long COVID,” describes persistent symptoms following recovery from SARS-CoV-2 infection. Early identification of circulating biomarkers...

Association of Autonomic Dysfunction With Long COVID: Evaluation Using Quantitative Autonomic Testing BACKGROUND Persistent symptoms (eg, heart palpitations, lightheadedness, fatigue) despite resolution of acute COVID-19 infection is termed “long COVID syndrome” or simply “long COVID.” Long...

Omics-based computational approaches for biomarker identification, prediction, and treatment of Long COVID Long COVID, or post-acute sequelae of COVID-19 (PASC), is a major global health problem, with cumulative estimates suggesting that around 400 million people worldwide have been affected...

Interrogating pulmonary diffusing capacity in long COVID: insights from DLCO and DLNO testing INTRODUCTION The lingering respiratory effects of COVID-19, particularly in patients with Long COVID, remain poorly understood, prompting a comprehensive evaluation of lung function in this...

Neurofluid circulation changes during a focused attention style of mindfulness meditation Neurofluids, including cerebrospinal fluid (CSF) and interstitial fluid, circulate through regulated central nervous system pathways to clear cerebral waste and support brain health, with elevated CSF...
