Feeling sleepy and less enthusiastic during the day may indicate a higher risk of developing a syndrome that often leads to dementia, a new study has found.

A study involving older people found that sleep problems were associated with a higher risk of developing a predementia syndrome.

Experiencing excessive daytime sleepiness as an older adult can spell dire consequences that ultimately may lead to full-blown dementia, according to a new study funded by the National Institute on Aging.

A study found people with excessive daytime sleepiness and a lack of enthusiasm to get things done were more likely to develop dementia.

Excessive daytime sleepiness could be an early sign of a pre-dementia condition called motoric cognitive risk syndrome (MCR), a study suggests.

People who have a hard time staying awake during the day or struggle to be enthusiastic about activities may be at risk for a condition that could lead to dementia.
