Category Specific Confrontation Naming in Persons with Alzheimer's Disease.

Alzheimer's Disease (AD) is characterized by degeneration in the physical ability and the cognitive-linguistic functioning skill of an individual. Naming deficits have been a recognizable and widely exhibited impairment which have been analyzed in various forms in persons with AD. The present study aimed at investigating the category specific naming (living and nonliving) through a visual confrontation task. 28 Malayalam speaking individuals with AD with varying severity mild-moderate (N= 16) and severe (N= 12) were considered for the study. A total of ten socio- cultural based living and nonliving objects were considered for the study. Statistical analysis revealed that the performance in the naming were significantly better for persons with mildmoderate degree of AD as compared to the severe group across the living and nonliving categories. However, the living items were named better than the non living items. Evidences also reveal that the severe group enhanced their naming ability with the phonologic cues as compared to the mildmoderate group who relied on the semantic cues. Thus, the outcome of this study implies the importance of items used in confrontation naming in linguistic profiling and rehabilitation. The effect of cues as naming facilitator is also interesting in these population. [ABSTRACT FROM AUTHOR]
