Micro-Awakenings Linked to Genetic Alzheimer's Risk

A study from the University of Liege found that frequent micro-awakenings during sleep are linked to a higher genetic risk of developing Alzheimer's disease.

Researchers tracked 500 healthy adults with an average age of 59, discovering that sleep disruptions correlate with genetic vulnerability long before memory problems appear.

The study suggests the locus coeruleus, a brainstem region involved in sleep regulation, may be an early site for protein deposits associated with Alzheimer's development.
