How Long COVID Affects Blood Flow in the Brain
The study found thickening of the carotid artery walls in all patients with a history of COVID-19 and reduced vasomotor reactivity in this group, indicating impaired cerebral blood flow post-infection.
Similar Autonomic Nervous System Problems in Long COVID and ME/CFS
A study comparing people with Long COVID, ME/CFS, and healthy controls found that Long COVID and ME/CFS share similar problems with autonomic nervous system function with overlapping biological features.
Increased phosphorylated tau (pTau-181) is associated with neurological post-acute sequelae of coronavirus disease in essential workers: a prospective cohort study before and after COVID-19 onset
New longitudinal data from essential workers suggests a neurological Long COVID subtype is associated with a marked rise in plasma pTau-181 (a biomarker often used in Alzheimer’s disease research) compared with pre-infection baseline.
