Scientists pinpoint brain immune cells as surprising culprit behind sleep loss in Alzheimer's

Researchers have discovered that the brain's own immune cells, microglia, may be the hidden driver of sleep disturbances in Alzheimer's disease, a finding that could open new treatment pathways. The study found that targeting these immune cells restored up to two hours of sleep in animal models without clearing amyloid plaques. Separately, scientists identified a protein called SORLA that protects the brain from toxic tau tangles, offering another potential target for Alzheimer's therapy.
