"The Key to Preventing Alzheimer's: One Critical Action to Take"

Deep sleep may play a crucial role in delaying the decline of brain health associated with Alzheimer's disease, according to a study involving older adults. Researchers found that individuals with Alzheimer's-related brain changes performed better on memory tests when they had more deep sleep, regardless of factors like education and physical activity. The study suggests that deep sleep acts as a "life raft" for memory, potentially helping to support cognitive function as dementia develops. The findings highlight the importance of sleep quality as a modifiable risk factor for Alzheimer's disease and suggest that lifestyle factors, such as getting enough deep sleep naturally, may help buffer against cognitive decline.
