- Abstract
Background: Recognizing emotional situations may be impaired in people with Alzheimer's disease (AD). Purpose: We examined differences in the comprehension of an emotional situation in healthy older controls (HOC) and individuals with mild and moderate AD. Research Design: cross-sectional study. Study Sample: We assessed a convenience sample of 115 participants in 3 contexts: understanding the situation, ability to name the congruent emotion, and choice of the correct face in 4 emotional situations (sadness, surprise, anger, happiness). Data Colection: Chi-square and Mann-Whitney U tests were used for comparison between groups separated by CDR 1 and 2. Chi-square and Kruskal-Wallis tests were also used for comparison between groups separated by CDR 0, 1, and 2, with a pairwise comparisons analysis. Results: We found that the ability to understand, name, and choose the proper emotion is not linked and depends on the portrayed emotion. Conclusions: The findings suggest an interaction between emotional processing and cognitive functioning. Therefore, knowledge of an emotional condition and the connection to a specific facial choice most likely involve 2 degraded areas of knowledge, resulting in even higher odds of inaccuracy., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.
