Sleep Disruption Damages Your Brain's Blood Vessels, Possibly Increasing Dementia Risk

Another reason to smash that snooze button.

Toronto researchers have determined that troubled sleep can damage our brain's blood vessels at the cellular level, potentially predisposing us to dementia.

If the findings are confirmed in clinical trials, sleep interventions could become an effective way to stop cognitive decline by preserving the structural integrity of small vessels in the brain.

“We know that in some individuals, sleep disruption can precede the onset of cognitive impairment by years, with emerging evidence suggesting a bidirectional link between sleep disruption and Alzheimer’s disease."
