Experimental Alzheimer's Treatment Restores Sleep in Mice, Targeting Glial Cell Dysfunction

Among the many cruelties of Alzheimer's disease, the theft of sleep is among the most intimate — unraveling not just rest, but the brain's own capacity to cleanse and repair itself each night. Scientists working with mouse models have now identified glial cells as a key driver of this disruption, and have developed an experimental treatment that restored roughly two hours of nightly sleep by coaxing those cells back toward their proper function. The finding matters not only as a potential comfort for patients and caregivers, but as a possible lever against the disease itself — since sleep is t
