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.

Older adults who reported excessive daytime sleepiness and a lack of enthusiasm were more likely to develop a condition that increases the risk of dementia.

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

People with the syndrome walk slowly and report memory problems, but they do not have a mobility handicap or dementia. Motoric cognitive risk syndrome is a condition that can develop before dementia.

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.

Feeling sleepy and lacking enthusiasm during the day could increase the risk of developing a cognitive disorder leading to dementia, a new study found. Sleep expert Dr. Wendy Troxel discusses.
