Poor sleep to increase the chances of Alzheimer's disease.

ISLAMABAD -- People who sleep less and those who experience low quality sleep have higher levels of a toxic protein in their brain which forms plaques that are the hallmark of Alzheimer's disease, a new study has found.

Researchers found that getting less sleep and poor sleep quality are associated with abnormal brain imaging findings suggesting Alzheimer disease (AD) in older adults, The CBC news Reported.

Deposits of beta-amyloid plaques are one of the hallmarks of AD.

Fluctuations in beta-amyloid levels may be regulated by sleep-wake patterns, the authors said.

Adam P Spira, of The Johns Hopkins Bloomberg School of Public Health, Baltimore, and colleagues used data from 70 adults (average age 76 years) in the Baltimore Longitudinal Study of Aging to examine whether self-reported sleep factors were associated with beta-amyloid deposition, which was measured by imaging of the brain.

Study participants reported sleep that ranged from more than seven hours to no more than 5 hours. Reports of shorter sleep duration and lower sleep quality were both associated with greater beta-amyloid build-up.
