Nightly sleep of five hours, less, may increase risk of dementia, death among older adults

Sleep and health are inextricably connected. New research from investigators at Brigham and Women’s Hospital explores the connection between sleep disturbances and deficiencies among older adults and risk of dementia and death, finding that risk of dementia was double among participants who reported getting less than five hours of sleep compared to those who reported 7-8 hours of sleep per night. The team also found associations between sleep disturbance and sleep deficiency with overall risk of death. Results are published in Aging.
