Feeling sleepy during the day? It might be more than just tiredness, especially if you're older. A new study found that people who feel exhausted and lack enthusiasm have a higher risk of developing something called motoric cognitive risk syndrome (MCR). This syndrome links to a slow walking speed and memory complaints in older adults. It's like a red flag for a condition that might lead to dementia.

The study looked at older adults over a few years. It turned out that those who had trouble staying awake or feeling enthusiastic were three times more likely to develop MCR. Doctors say this could help them spot early signs of brain problems.

But the study isn't perfect. It relied on people's memories of their sleep, not actual measurements. Plus, most participants were white, so the results might not apply to everyone. Still, it's a clue that sleep is super important for brain health.

 Experts think sleep might help clean the brain of harmful stuff. It also might affect how the brain responds to stress. They're still figuring out why only certain sleep problems, like daytime sleepiness, seem to matter. It could be that early brain changes cause sleep trouble, not the other way around.

So, if you're sleepy all the time, talk to your doctor. They might suggest a sleep test or ways to improve your sleep. A healthy lifestyle can also help protect your brain as you age.
