Research Links Extended Sleep Duration to Alzheimer's Biomarker

A new study suggests that older adults who consistently sleep ten or more hours nightly may exhibit elevated levels of phosphorylated tau 181 (p-tau181), an early indicator for Alzheimer's disease. While the research establishes an association rather than causation, it underscores a potential link between sleep patterns and brain health that warrants further investigation. This finding could contribute to earlier detection strategies for neurodegenerative conditions.
