What the research found
Scientists have uncovered an unexpected culprit behind sleep loss in Alzheimer’s disease: overactive immune cells in the brain. By temporarily removing these cells, researchers restored more than two hours of sleep per day in mice, revealing a promising new target for treatment.
Evidence level: Animal study. Results in animals or cells often don't carry over to people.
