The use of sleep medication and the inability to fall asleep quickly are associated with an increased risk of developing dementia over a 10-year period, according to a study. The research, published in the American Journal of Preventive Medicine, found a significant link between three measures of sleep disturbance and the risk of developing dementia, a neurodegenerative disease. The researchers associate sleep-initiation insomnia (trouble falling asleep within 30 minutes) and sleep medication use with a higher risk of developing dementia. They 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.
"We expected sleep-initiation insomnia and sleep medication usage to increase dementia risk, but we were surprised to find sleep-maintenance insomnia decreased dementia risk," explained lead investigator Roger Wong, an Assistant Professor at SUNY Upstate Medical University, US. The research is the first to examine how long-term sleep disturbance measures are associated with dementia risk using a nationally representative US older adult sample.
