Lack of sleep may play a role in Alzheimer's
A new animal study suggests that lack of sleep may be linked to the development of Alzheimer's disease, researchers say. Scientists in St. Louis found that levels of amyloid beta protein levels rose in mice while they were awake, and fell as they slept. And mice who were kept from sleeping had significantly higher levels of the brain plaque than those who slept normally. This protein build-up is linked to the development of dementia, researchers believe.
