Alzheimer's & Sleep Connection
- People with Alzheimer's experience sleep problems like nighttime wakefulness and daytime drowsiness.
- Scientists are investigating if sleep problems contribute to the onset of Alzheimer's.
Brain's Dishwasher
- During sleep, brain cells shrink, allowing cerebrospinal fluid (CSF) to flow through the brain, washing out toxins.
- This "glymphatic system" uses blood vessels as a scaffold for CSF to exchange with brain fluid.
Beta-Amyloid and Sleep
- Beta-amyloid, a waste product linked to Alzheimer's, builds up in the brain.
- Lack of sleep may accelerate the formation of beta-amyloid plaques, potentially increasing Alzheimer's risk.
