Frequent Sleep Disruptions Linked to Higher Alzheimer's Risk

A study of 500 healthy individuals by the University of Liège found that frequent nocturnal micro-awakenings in middle-aged adults are associated with a higher genetic risk of Alzheimer’s disease.

Researchers utilized polygenic risk scores to identify correlations, noting that while the link was absent in young adults, it was significant in participants aged 50 to 69.

The study, published in the journal Sleep, suggests that monitoring sleep quality could eventually serve as a non-invasive marker for identifying individuals at risk before clinical symptoms appear.
