The Profile of Task Performances for Cognitive-Communicative Intervention in Subjective Cognitive Decline

Abstract

Purpose: Cognitive-communication intervention for subjective cognitive decline (SCD) is based on the profile of task performances. The purpose of this study was to identify performances in cognitive-communication and quality of life, to provide the correlation and predictive tasks of communication among subjects with SCD.Methods: SCD group (n = 19) aged 65 and over performed subtasks for the 3 domains, compared with other amnestic mild cognitive impairment (n = 22) and control (n = 24) groups.Results: The main outcomes were as follows. Firstly, the SCD and other two groups had significant differences in performances of executive function (planning/activating) and subjective communication. Secondly, semantic performances in the SCD group were significantly correlated with all cognitive tasks, and reasoning was the strongest predictor of communication. Lastly, discourse had significant correlations with all cognitive tasks in the SCD group. Reasoning (deductive/inductive) and executive function (planning) were also found to be the best predictors of communication.Conclusion: Current study provides a cognitive-communication profile to reduce the risk to develop neurological disease. These results also facilitate the preventive intervention for SCD, warranting its effect.
