Clinical Manifestations.

Background: Greater physical activity (PA) is associated with better cognitive and vascular health, but accurate assessment of PA is challenging. Self-report questionnaires of PA may be compared against objective measures from smartwatch sensors; the correspondence between measures may be influenced by a variety of factors such as cognition or age. The focus of this study was to identify baseline participant characteristics (vascular risk, cognition) that influence the association between self-reported PA and PA measured with a Garmin Vivosmart 4 smartwatch in a racially diverse sample of older adults.

Clinical Manifestations.

Background: The Goal-Control Model posits that episodic memory impairment leads to premature decay of everyday task goals, which contributes to task omissions (failure to accomplish task steps) in those with moderate to severe impairment. Although task omissions are not observed in those with mild episodic memory (mildEM) impairment, it has yet to be investigated if goal decay is reflected by subtle errors during task completion. We hypothesized that goal decay in mildEM impairment is reflected by imprecision in task performance at the end of everyday tasks.

Clinical Manifestations.

Background: Subtle changes in naturalistic language have been associated with cognitive abilities in older adults. This study explored script generation as a method for detection of mild cognitive impairment (MCI). Differences in human-coded speech analysis of scripts were examined between MCI vs.
