Role of sleep-related brain activity in clearing toxic proteins and preventing Alzheimer’s disease

Evidence of sleep-dependent low-frequency (less than 0.1 Hz) global brain activity in the clearance of Alzheimer’s disease-related toxin buildup is presented in new research. This neuronal activity was more strongly linked with cerebrospinal fluid flow in healthy controls than higher risk groups and patients, and the findings could serve as a potential imaging marker for clinicians in evaluating patients.
