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.

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.

The condition affects roughly six million Americans, although experts believe the real number may be closer to 30 million.

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.

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.
