Overview

  • Research indicates a 27% increased risk of dementia with each 1% annual loss of slow-wave sleep in individuals over 60.
  • Slow-wave sleep is crucial for brain health, aiding in the removal of waste and toxic proteins linked to Alzheimer's disease.
  • Motoric Cognitive Risk (MCR) syndrome, characterized by slow walking and memory complaints, doubles dementia risk.
  • Daytime dysfunction, such as sleepiness and lack of enthusiasm, is linked to a 3.3 times higher risk of MCR.
  • Experts emphasize the importance of addressing sleep issues early to potentially prevent cognitive decline.
