Daytime Sleepiness Could Be an Early Sign of Dementia, New Study Suggests
A new study published in Neurology suggests that daytime drowsiness and lack of enthusiasm may indicate a heightened risk of cognitive decline in older adults, potentially serving as early warning signs of dementia. The findings highlight a possible link between daytime sleepiness and the likelihood of developing motoric cognitive risk syndrome (MCR), a precursor to dementia.
The research, led by a team from the Albert Einstein College of Medicine in the Bronx, New York, involved 445 participants with an average age of 76. None of the participants had dementia at the start of the study. Researchers conducted annual assessments over three years, examining sleep quality, daytime alertness, memory issues, and physical mobility through a series of tests, including treadmill assessments to evaluate walking speed.
What is Motoric Cognitive Risk Syndrome (MCR)?
MCR is a condition associated with slowed walking speed and mild memory difficulties, often preceding more severe cognitive conditions like dementia. The presence of MCR is particularly concerning, as it can be an early sign of cognitive impairment, yet it often goes unnoticed until more serious symptoms arise.
The study’s lead author, Dr. Victoire Leroy, MD, PhD, emphasized the importance of early detection, noting, “Our findings suggest that sleep issues affecting daytime wakefulness are most strongly associated with later cognitive risk. This supports the hypothesis that sleep-related problems, particularly daytime sleepiness, are connected to cognitive impairment in older adults.”
Key Findings: Daytime Sleepiness and Cognitive Health
Researchers found that individuals who reported frequent daytime drowsiness, difficulty staying awake during routine activities like eating or socializing, and a general lack of enthusiasm for daily tasks were over three times as likely to develop MCR than their more alert counterparts. These findings remained significant even after adjusting for factors like age, depression, and other health conditions.
The study also points to the broader impact of sleep disturbances on cognitive health. Issues such as excessive sleepiness during the day may not only affect mood and motivation but may also serve as early indicators of declining brain health.
Practical Takeaways: Improving Sleep for Better Cognitive Health
For those concerned about sleep quality and cognitive health, simple lifestyle adjustments may offer some protection. Experts often recommend establishing a consistent bedtime routine and engaging in calming activities before bed, such as reading or gentle stretching, to improve sleep quality. Limiting screen time in the evening and avoiding caffeine and heavy meals before bed are also proven strategies for enhancing sleep.
Early Intervention and Health Monitoring
The study’s findings underscore the importance of paying attention to changes in daily alertness and motivation, especially among older adults. Detecting MCR early can allow for interventions that may slow cognitive decline, improving the quality of life and overall brain health.
As awareness grows around dementia prevention, identifying early symptoms like daytime sleepiness could prove invaluable for those looking to safeguard their cognitive health. If you or someone you know frequently experiences daytime fatigue and a noticeable drop in enthusiasm, consider consulting a healthcare provider to discuss sleep patterns and explore preventive measures.
