Highlights POTS causes cardiovascular instability and severe symptoms. Postural hyperventilation is thought to cause POTS, but the mechanisms are unclear. Reduced stroke volume and brain perfusion drive postural hyperventilation in POTS. Stroke volume and brain perfusion should be targeted as...

Abstract Neuroimaging studies have indicated that altered cerebral blood flow (CBF) was associated with the long-term symptoms of postacute sequelae of SARS-CoV-2 infection (PASC), also known as “long COVID”. COVID-19 and long COVID were found to be strongly associated with host gene expression...

Introduction: During a standard 70-degree head-up tilt test, 90% of adults with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) develop an abnormal reduction in cerebral blood flow (CBF). A 70-degree test might not be tolerated by young ME/CFS patients because of the high incidence...
