The Sleep-Alzheimer’s Link: How Disrupted Rest Accelerates Brain Pathology
A major longitudinal analysis of over 1,200 participants from the Alzheimer’s Disease Neuroimaging Initiative provides robust clinical evidence linking sleep disturbance to the progression of Alzheimer’s pathology. The study found that baseline sleep problems were associated with a faster rate of decline in cerebrospinal fluid amyloid-beta 42 levels, a key biomarker of Alzheimer’s disease. To uncover the molecular mechanisms, researchers integrated CSF proteomics with advanced network analysis, identifying a specific protein module that connects sleep disturbance to amyloid dynamics.
