Lack of deep sleep may pave way for Alzheimer’s, researchers say

January 18, 2016


Forget about needing beauty sleep. It’s your brain that may suffer the most from a lack of deep shut eye.

Brain researchers have long noticed a connection between sleep disorders and memory problems. More recently, the link between disrupted sleep and an increased risk of Alzheimer’s disease has been documented by researchers at the University of California, Berkeley.

It’s believed that sleep acts like a dustbin for the brain — cleaning out toxins, including harmful proteins tied to Alzheimer’s.

Recent animal studies show sleep’s cleansing process in action. But now scientists at Oregon Health & Science University are preparing to conduct a study on humans that would further explain deep sleep’s effect on human brains.

Their biggest challenge: finding a minimally invasive way to study the human brain at work while the patient sleeps.

On that note, sweet dreams.
