Mysterious brain cells clear proteins that contribute to Alzheimer's disease
Tanycytes, specialized brain cells, transport toxic tau proteins from cerebrospinal fluid into the bloodstream, but malfunction in Alzheimer's disease, causing tau accumulation in the brain.
Sleep-loss–related attentional lapses trigger brainwide state changes that drive cerebrospinal-fluid–mediated cleansing, protecting the brain from damage caused by lost sleep.
Expert reveals the best sleep position to protect against memory loss
Side-sleeping promotes cerebrospinal fluid circulation and glymphatic clearance, reducing accumulation of Alzheimer-related proteins and supporting long-term memory health versus back or stomach sleeping.
