Disrupted sleep in one’s 50s, 60s raises risk of Alzheimer’s disease

"People who report a declining quality of sleep as they age from their 50s to their 60s have more protein tangles in their brain, putting them at higher risk of developing Alzheimer’s disease later in life, according to a new study by psychologists at the University of California, Berkeley.

The new finding highlights the importance of sleep at every age to maintain a healthy brain into old age."
