Study Links Sleep Behaviors to Increased Dementia Risk in Older Adults
A recent study published in the journal Alzheimer's & Dementia has identified three sleep behaviors that are linked to brain damage and an increased risk of dementia, including Alzheimer's disease. The research involved brain scans and questionnaire responses from over 23,000 middle-aged and older adults. The study focused on five sleep behaviors: sleep duration, daytime napping, sleeplessness, unintentional daytime dozing, and snoring. Among these, sleeping outside the recommended seven-to-nine-hour range, frequent daytime naps, and sleeplessness were associated with greater white matter lesions in the brain, which are linked to a higher risk of dementia. The study highlights the importance of sleep as a modifiable risk factor for dementia and suggests that improving sleep quality could help in dementia prevention.
