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.

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.
