The time at which people go to bed and how long they sleep may affect their risk of developing dementia and cognitive decline, a new study suggests. The results were published Wednesday in the Journal of the American Geriatrics Society. A team of researchers from China, Sweden and the United Kingdom found a 69% higher risk of dementia in individuals who slept for more than eight hours, versus sleeping seven to eight hours, and a two-times higher risk for people drifting off before 9 p.m. versus 10 p.m. or later. Moreover, the findings suggest "cognitive function should be monitored in older adults who report prolonged time in bed and advanced sleep timing, especially in older individuals aged 60 to 74 years and men," the research paper said.
