Unawareness of social interaction and emotional control deficits in alzheimer's disease

Abstract

The purpose of this study was to examine unawareness of deficit in Alzheimer's disease (AD) in a previously unexplored functional domain: social interaction and emotional control competency. Impairment of awareness was measured by calculating the degree to which patients and their caregivers disagreed on ratings of patient functioning. to assess potential underlying mechanisms or associated features of social/emotional unawareness, a regression equation examining disease and demographic correlates was created. In addition, to provide a basis of comparison for the social/emotional domain, unawareness of deficit was also assessed in two previously examined domains of functioning (i.e., cognitive and self-care competency). Results revealed that, as compared to caregivers, AD-diagnosed patients overestimated their social/emotional competency but to a lesser extent than they overestimated cognitive and self-care competencies. Regression analysis suggested that impaired awareness of social interaction and emotional control deficits was positively correlated with dementia severity and negatively correlated with education.
