Deep Sleep: A Key to Protecting Brain Health

Deep sleep may hold the key to slowing declines in brain health that could lead to Alzheimer’s disease, the most common form of dementia. In a 2023 study published in Science Alert, researchers from UC Berkeley, Stanford University, and UC Irvine found that cognitively healthy older adults with brain changes associated with Alzheimer’s performed better on memory tests when they experienced more deep sleep. This discovery emphasizes the vital role of deep sleep in maintaining cognitive function and potentially mitigating the progression of neurodegenerative conditions.
