Sleep Problems May Cause Dementia

Parent Interventions

Sleeping less than six hours per day may lead to the onset of dementia at a later stage, according to a study done by the University College of London (UCL). An analysis of 7,959 British adults and their self reported sleep patterns six times between 1985-1988 and 2015-16. The researchers found that those who slept six hours or less each night while middle-aged were significantly more likely to develop dementia later in life, compared to those who slept seven hours per night. They did not find any significant link between sleeping for eight or more hours and dementia risk. The researchers found that the association was independent of potentially confounding factors such as mental health, or differences in behaviour, socio-demographic status, or heart health. Previous studies reported an increase in dementia risk among those who sleep for longer than average, but results were inconsistent.
