Summary
13 common AQP4 gene variants altered how poor sleep tracked with Alzheimer’s-related brain and cognitive changes, Edith Cowan University researchers reported in Alzheimer’s & Dementia.
Shorter sleep was tied to faster grey matter loss in some carriers, while longer time to fall asleep was linked to lower brain volume in others, suggesting the same sleep problem can affect brains differently by genotype.
Cognitive performance also changed differently over time across sleep-disturbed participants, with some AQP4 variants appearing harmful and others protective depending on sleep habits.
The findings point to more personalized Alzheimer’s prevention strategies and future trials that combine sleep interventions with genetic information, though the team said the results still need replication in larger, more diverse groups.
