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

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.
