Researchers at the University of Kentucky have found that brain immune cells contribute to sleep disruption in Alzheimer's disease. In a study involving mice, they restored over two hours of sleep daily without removing amyloid plaques by temporarily eliminating most of these immune cells. This challenges the traditional view that sleep problems are primarily due to neuron damage or plaque accumulation, suggesting that the inflammatory response from immune cells may be a significant factor. The findings could lead to new treatment strategies for sleep disturbances in Alzheimer's patients.
Key facts
- Researchers restored over two hours of sleep in mice with Alzheimer's-like changes.
- The study was led by Shannon L. Macauley, Ph.D., at the University of Kentucky.
- Temporary elimination of immune cells allowed for longer and deeper sleep.
- The research suggests that the immune response may significantly contribute to sleep disruption.
- Alzheimer's primarily disrupts non-rapid eye movement (NREM) sleep.
