Beyond sleep: Rest and activity rhythm as a marker of preclinical and mild dementia in older adults with less education.

ABSTRACT:

Background

Although sleep duration and sleep-related breathing disorders were associated with dementia previously, few studies examined the association between circadian rhythm association and cognitive status.
