Improving sleep and other lifestyle factors keys to better brain health

Sleep is our body’s way of restoring its vital organs including the brain. But what happens when sleep is elusive over a long period of time? Research shows that the lack of consistent sleep can impact our brains in negative ways and increase our risk for Alzheimer’s and dementia.

A research review in Nature Communications recently concluded that persistent short sleep durations of six hours or less at age 50, 60 and 70, as compared to a normal night’s sleep of seven hours, was associated with a 30% increase in dementia risk. The study looked at research that followed participants for 10 years or more.

So, what happens in our brains while we sleep? “Sleep is a restorative function,” explained Jeremy Pruzin, MD, a memory care expert at Banner Alzheimer’s Institute in Phoenix. “While we sleep the brain repairs synapses and clears substances, including the beta-amyloid protein associated with Alzheimer’s disease.”
