Hi there! There’s some important news out of the U.S. about health and daytime sleepiness that we should talk about. A new study in “Neurology”, published by the American Academy of Neurology, says that feeling sleepy during the day might be more than just fatigue—it could actually signal an increased risk for a pre-dementia condition.
Here’s the latest:
Researchers from the Albert Einstein College of Medicine in New York have highlighted a condition known as “motoric cognitive risk syndrome” (MCR). If you often feel sleepy during the day or have little motivation to get things done, you might be at higher risk of developing MCR. This syndrome is a step before dementia and is usually marked by a slower walking speed and mild memory problems, though it doesn’t necessarily mean one has dementia yet.
Dr. Victoire Leroy, who led the study, explained that noticing these symptoms could help prevent more severe cognitive issues in the future. The goal is to get people to address sleep issues sooner, which could lead to better long-term health.
So, what’s this study all about?
The researchers studied 445 people with an average age of 76, none of whom had dementia at the study’s start. Participants filled out sleep questionnaires, detailing issues like trouble falling asleep or waking up too early, often feeling hot or cold, and if they used sleep medications. Another part of the study looked at how sleepy participants felt during the day, including situations like staying awake during meals or social events.
Additionally, researchers observed participants’ walking speeds on a treadmill, checking for any slowing down year after year. They then tracked these participants over three years to see who developed MCR.
Here’s what they found:
About 177 people had poor sleep quality, while 268 were considered good sleepers.
Of those with poor sleep, 42 already had MCR at the study’s start. During the study, 36 more people developed MCR.
Those with excessive daytime sleepiness or low enthusiasm were over three times more likely to develop MCR.
While this study doesn’t prove that sleep problems cause MCR, it does show a strong connection. The message is clear: keeping sleep quality in check might help reduce risks later on.
How is sleep related to dementia?
Dr. Verna Porter, a neurologist not involved in the study, shared some insights. She said that while some daytime sleepiness is normal as we age, extreme drowsiness and lack of motivation are different. She pointed out that such sleep disturbances—like sleep apnea or chronic insomnia—can lead to serious health concerns over time.
People who feel sleepy even when not very active may need to address these issues now. Porter explained that untreated sleep disorders might also increase risks for heart disease and other conditions linked to cognitive decline.
Are sleep issues in younger people a concern too?
Definitely! This study focused on older adults, but experts believe that younger adults experiencing sleep disturbances, like chronic sleep apnea or fragmented sleep, may also be at higher risk of dementia later on.
Dr. Steve Allder, a neurologist, emphasized the need to manage sleep health earlier in life. “Middle-aged adults with poor sleep habits are likely setting themselves up for risks of dementia later,” he said. Taking steps like exercising, eating well, managing stress, and sticking to regular sleep schedules can help. Avoiding screen time before bed and having a comfortable sleep environment also make a big difference.
What can help improve sleep quality and protect cognitive health?
To get better sleep and protect your brain health, here are some tips from experts:
1. Exercise: Aim for at least 150 minutes of moderate activity, like walking or yoga, each week.
2. Healthy Diet: Include plenty of fruits, vegetables, and omega-3 fats to support brain function.
3. Sleep Routine: Go to bed and wake up at the same time each day. This can improve sleep efficiency, or how much time you’re actually asleep while in bed.
4. Avoid Late Night Stimulants: Limit caffeine and alcohol, which can disrupt your sleep.
5. Stress Management: Practice relaxation techniques like yoga or mindfulness exercises to help unwind before bed.
The study does have some limitations. For example, it relied on participants’ self-reports about their sleep habits, which may not be entirely accurate. Still, the findings underscore how important good sleep is to overall health, especially as we age.
This is a reminder that sleep isn’t just about feeling rested; it’s about long-term health, too. If you’re often tired or lacking motivation, it could be worth talking to your doctor. Addressing sleep issues now may make a difference for years to come.
