Poor quality sleep and compulsive need for daytime napping linked to early onset of Alzheimer's, warns study

Measuring how people sleep may be a non-invasive way to screen for Alzheimer's disease before or just as people begin to develop problems with memory and thinking.
UPDATED JAN 13, 2019

Scientists are of the opinion that people who have the compulsive need for a daytime nap in spite of proper long night sleep, might be at the risk of developing dementia. The finding, published in Science Translational Medicine, states that less sleep might cause in the accumulation of tau proteins that can form tangles in the brain.

With a group of around 119 volunteers aged 60 and over- of whom 80% were mentally healthy and the remaining mildly impaired, researchers were able to draw the conclusion that those who do not get quality sleep might suffer from losing memory or confusion.

The magazine states, "In patients with Alzheimer’s disease (AD), amyloid-β (Aβ) plaques and tau protein tangles accumulate in the brain long before the appearance of clinical symptoms. Early intervention is critical for slowing neurodegeneration and disease progression."
