Study: Sleep ‘Detoxes’ the Brain of Alzheimer-Linked Toxins

University of Rochester study examined lab mice


A study shows that our brains may be getting rid of the gunk that builds up throughout the day when we sleep.

Fox News reports that the study — conducted by scientists at the University of Rochester Medical Center — examined mice as they slept and found out that their brains clean themselves at night. This data could help scientists find new ways to treat diseases such as Alzheimer’s. Scientists also noticed that brain cells tend to shrink when we sleep, allowing waste to pass through easily.

The research was done for Friday’s issue of the journal Science. It was funded by the National Institute of Neurological Disorders and Stroke.
