A - 61 The Impact of Metacognition on Everyday Functioning in Mild Cognitive Impairment and Dementia.

Abstract

The purpose of this study was to evaluate the role of metacognition on everyday functioning in mild cognitive impairment and dementia. Participants included 44 healthy older controls, 57 individuals with mild cognitive impairment (MCI), and 26 individuals with Alzheimer's disease (ad). Participants were administered verbal and nonverbal memory tests and a visuospatial test. They made predictions about their performances before taking each test and then made postdictions about their performances after each test. Prediction and postdiction accuracy scores were calculated. Additionally, all participants took the Everyday Cognition (ECog) Scale. Regression analyses were conducted, separately for each diagnostic group, to determine the roles of prediction and postdiction accuracy on everyday functioning. For healthy older controls, prediction and postdiction accuracy on a visuospatial test significantly impacted overall everyday functioning. In MCI, prediction accuracy on a nonverbal memory test significantly impacted everyday functioning. Finally, in ad, postdiction accuracy on a nonverbal memory test significantly predicted everyday memory. Overall, metacognition predicts everyday functioning in healthy aging, MCI, and ad. For healthy aging and MCI, the ability to both accurately predict and retrospectively evaluate their own cognition impacts overall everyday functioning. With the increased cognitive impairment of ad, only the ability to retrospectively evaluate performances impacts everyday memory.
