Adding to the growing body of evidence on sleep disturbances and cognitive impairment, new research finds significant links between three measures of sleep disturbance and the risk for developing dementia over a 10-year period. The results associate sleep-initiation insomnia (trouble falling asleep within 30 minutes) and sleep medication use with higher risk for developing dementia. The investigators also found that people who reported having sleep-maintenance insomnia (trouble falling back to sleep after waking) were less likely to develop dementia over the course of the study.
