Poor quality of sleep in older people links to neurodegenerative processes in Alzheimer’s

Takeaway

  • Cognitively-normal older people who have a poor quality of sleep show atrophy in brain regions known to be affected in Alzheimer’s disease patients.

Why this matters

    The relationship between the poor quality of sleep found early in the course of dementia and the atrophy found in particular brain regions is poorly understood; this study emphasizes the importance of sleep intervention to prevent neurodegeneration in Alzheimer’s-related brain regions.
