Daytime sleepiness does not just make afternoons a little tougher to get through. According to a recent study, it could signal early signs of dementia. When daytime sleepiness and a lack of enthusiasm start impacting everyday life, it might indicate something deeper. A condition that may eventually lead to dementia.
In this study, researchers examined older adults experiencing these symptoms and found that they were more likely to develop motoric cognitive risk syndrome, a precursor to dementia.
Motoric cognitive risk syndrome, often shortened to MCR, is a condition that doesn’t often make headlines. It involves slower walking speed and some memory issues, two factors linked to an increased risk of dementia. So, identifying these early signs is crucial. The researchers suggest that addressing daytime sleepiness could be a key part of early intervention strategies.
The Hidden Connection Between Daytime Sleepiness and Cognitive Health

In the study, researchers looked at data from 445 adults around the age of 76, none of whom had dementia at the start. They used detailed questionnaires to explore each participant's sleep quality, focusing on nighttime sleep disturbances and daytime sleepiness.
These questions were not just about how often participants had trouble falling asleep or waking up in the night. They also touched on how often they felt daytime sleepiness and how it impacted their daily activities.
The findings were eye-opening. Forty-two of the participants showed signs of motoric cognitive risk syndrome from the start, with symptoms like slower walking speed and mild memory issues. Over a three-year period, another 36 people developed MCR. Those who frequently experienced daytime sleepiness and a lack of enthusiasm were over three times more likely to develop MCR.
Thus, it is a strong signal that daytime sleepiness may be an early red flag for cognitive decline.
Daytime Sleepiness Is More Than Just Feeling Tired
Sure! Daytime sleepiness may seem harmless. But it can be a symptom of underlying issues with brain health. Sleep is essential for repairing and refreshing the brain, which is why quality sleep is so crucial as we age. Daytime sleepiness can suggest that the brain is not getting the restorative sleep it needs.
Over time, this lack of quality rest may contribute to cognitive decline, potentially leading to conditions like MCR.

The link between daytime sleepiness and MCR hints that our bodies might be signaling brain changes through subtle signs like a lack of alertness or enthusiasm. While it might feel normal to be a little sleepy or unmotivated, frequent daytime sleepiness could mean more than a poor night's sleep. It might be an early indication of a more serious issue.
What Is Motoric Cognitive Risk Syndrome?
Motoric cognitive risk syndrome, or MCR, might sound unfamiliar. But its symptoms are surprisingly common. This condition is marked by slower walking speed paired with mild memory difficulties. Slower walking might seem like a minor inconvenience, but combined with memory issues, it can signal a higher risk of dementia.
The brain relies on coordinated systems to control movements and cognitive functions. So, when one area is affected, it can hint at wider impacts.
Interestingly, MCR is not about dramatic memory loss or serious mobility issues, which might make it easier to overlook. The signs are subtle - a bit of forgetfulness here, a slower pace there. However, these small changes can point to a shift in the brain's overall function.
