Deep Sleep Time Measured by Wearable Device Associated with Amyloid Burden in the Elderly with Subjective Cognitive Decline.

Factors other than age and genetics may influence the development of Alzheimer’s disease. In particularly, there is growing evidence that sleep disturbances are associated with increased β‐amyloid burden. We investigated the association between sleep characteristics measured with a wearable device and β‐amyloid burden in the elderly diagnosed with subjective cognitive decline.
