Scientists Restore Two Hours of Sleep in Alzheimer’s Mice Without Removing Plaques
20 Temmuz 2026Science Daily
- Researchers have identified the brain's immune cells as a key factor in sleep loss associated with Alzheimer’s disease. In experiments with mice that had amyloid plaques, it was found that overactive microglia caused inflammation, disrupting deep sleep.
- Remarkably, when most of these immune cells were temporarily removed, the mice experienced an increase of more than two hours of restorative sleep, despite the presence of the plaques.
- Alzheimer’s disease is characterized by the accumulation of amyloid plaques and tau tangles in the brain, leading to cognitive decline. Sleep disturbances are common in Alzheimer’s patients, contributing to the progression of the disease.
- This discovery shifts the focus from amyloid plaques to the role of microglia in sleep regulation in Alzheimer’s disease. It suggests that targeting the inflammatory response of these immune cells could be a potential therapeutic avenue for improving sleep quality in patients.
