Self-reported sleep disturbances may be related to a higher risk of developing Alzheimer's disease, according to the results of a study conducted at Uppsala University, in Sweden, which were recently published at the Alzheimer's & Dementia journal. The researchers analyzed data that included 40 years of self-reports, and concluded that older men who suffered sleep disorders were also more likely to develop the neurologic disease than ones who did not report any problems in sleeping.
The study included more than 1,000 people who were 50 years old at the time the study began in 1970, and were followed until 2010. The researchers demonstrated that, during the 40 years of reports sleep disturbances were related to Alzheimer's disease, especially in the last years of study when the participants were older. In addition, the scientists explained that their research suggested that sleeping better may improve men's brain health.
"We demonstrate that men with self-reported sleep disturbances run a 1.5-fold higher risk to develop Alzheimer's disease than those without reports of sleep disturbances during a 40-year follow-up period," explained the leader of the study, Christian Benedict, who is a sleep researcher at the
