ICF-Based Analysis of Communication Disorders in Dementia of Alzheimer's Type

Abstract

Purpose: Dementia of Alzheimer's type (DAT) is a major cognitive communication disorder. The present study attempted to analyse communication disorders in DAT in the International Classification of Functions (ICF) framework. The study investigated the impact of the severity of communication disorders in persons with DAT on activity participation and environment components of the ICF. Method: Thirty bilingual individuals with DAT in the age range of 65-88 years were classified into three groups of mild, moderate and severe degree of dementia. Forty-three items of the American Speech-Language-Hearing Association Functional Assessment of Communication Skills for Adults (ASHA FACS) were linked to the ICF framework. A few additional items were also added for a complete profiling of DAT. A total of 50 (ASHA FACS + ICF) items were rated and administered for the purpose of the study. Results: The study revealed a disproportionate impact of the severity of DAT on activity participation and environment components of the ICF. Conclusion: The present study investigated the utility of the ICF framework for profiling the functionality of persons with DAT. This profiling highlighted the need for ensuring effective communication and quality of life in the DAT population.
