Self‐reported sleep duration is not associated with pet amyloid deposition in the oldest‐old: The 90+ Study

Background Some, but not all cross‐sectional studies have suggested a relationship between sleep and PET‐measured amyloid burden in older adults without cognitive impairment. It is hypothesized that amyloid clearance from the brain is related to sleep duration. Our aim is to examine the cross‐sectional association between self‐reported sleep duration and amyloid accumulation in the oldest‐old (90+ years), a group with high prevalence of amyloid...
