Research has shown that unpleasant dreams in middle age may be a sign of future dementia. Especially if they are seen at least once a week.
Each of us from time to time faced terrible and unpleasant dreams, but for the majority they remained something like childhood memories that we want to forget about. However, if you began to see these terrible dreams in middle age, and with an intensity of at least once a week, then this indicates the likelihood of facing a faster decline in cognitive functions. Scientists at the University of Birmingham have found a link between frightening dreams and an increased risk of dementia.
Fearful dreams prepare for a harsh reality
If the results of this study are confirmed, it could eventually lead to the development of new ways to diagnose dementia and preventive interventions that will slow down the rate of decline in intelligence. According to statistics, approximately 5% of adults have nightmares from which they are able to wake up at least once a week.
