A recent study highlights a concerning connection between poor sleep habits and the development of motoric cognitive risk syndrome (MCR) in seniors. Those aged 70 and older who experience excessive daytime drowsiness or a lack of interest in activities may be at an increased risk of dementia, according to research led by Dr. Victoire Leroy from Albert Einstein College of Medicine.
The study involved 445 dementia-free participants, averaging 76 years old, who completed sleep questionnaires and treadmill assessments over three years. MCR, characterized by slow walking and memory difficulties, affects 2 to 27% of the global population. Out of the participants, 177 were identified as poor sleepers and 268 as good sleepers. At the study’s start, 42 participants had MCR, with an additional 36 developing the syndrome during the study.
After adjusting for age, depression, and other health issues, researchers found that excessive daytime sleepiness and lack of enthusiasm were associated with over three times the risk of developing MCR. While the study indicates a correlation, further research is necessary to establish a direct causal relationship. The findings were published in the journal Neurology, emphasizing the need for better sleep management to potentially prevent cognitive decline.
