Awareness of functional ability in people with early-stage dementia.

Abstract

Assessment of functional ability in people with early-stage dementia (PwD) is an important area of study because it forms part of the diagnostic process and may help in monitoring disease progression. Most researchers and clinicians rely on informant ratings rather than observing actual functional performance or employing self-ratings. There has however been little research to verify whether informant ratings of functioning are accurate, and there has been even less research investigating the accuracy of self-ratings of functional ability in PwD. No study has used the performance-monitoring metacognitive approach to investigate awareness of functional ability.
