A recent population-based study observed almost 2000 older adults who were free of dementia at baseline. After adjusting for the confounders, results showed that longer time in bed and earlier bedtimes were significantly associated with increased dementia risk. For every 1 hour that bedtime was advanced, a 25% increased risk for dementia was associated, and the risk for dementia was 69% higher in those who slept more than 8 hours daily compared with those who slept 7-8 hours daily. Dementia risk was twice as high for those who went to bed before 9 PM vs 10 PM or later. These associations were strongest among men and people aged 60-74 years.
