Researchers at the University of Arizona have found that poor sleep is not merely one risk factor among many for dementia, but a common thread woven through multiple pathways to cognitive decline. Three specific sleep habits correlate with measurable damage to brain tissue and accelerated aging — a finding that moves the conversation from statistical association into visible biological consequence. What gives this work its quiet urgency is that sleep, unlike genetics or early life circumstance, is something a person can change.
