Introduction: DAT (Dementia of Alzheimer's Type) is one of the commonest types of dementia. The communication deficits of this population are largely confined to the two aspects of language: lexicon and pragmatics. The most frequently cited language deficits in the literature include difficulty with verbal memory, word finding, disruptive vocalizations, and understanding of spoken language (i.e., auditory comprehension deficits). However, there are very few studies focused on cross language comparisons exhibited by these individuals. Especially, there are very less number of studies on this aspect in Indian context, too.
Aim: The aim of the present study was to study the cross language variations in language deficits in DAT individuals in English and Kannada.
Method: 30 individuals with DAT in the age range of 45 to 65 years were taken as subjects for this study. All the subjects were assessed on Dementia Assessment Battery (DAB) in English and in Kannada, which is developed for the present study. DAB consists of four domains, memory, linguistic comprehension, linguistics expression and visuospatial construction with each domain consisting of several subtests. Thirty age and gender matched normal subjects were taken as control group for this study.
Results: Individuals with DAT showed poor performance when compared to control subjects. Moreover, across languages, DAT individuals performed well in frequently used language when compared to other.
Discussion: The results of the present study are discussed in terms of cross language variations that are seen in these subjects and its implications in speech - language - communication intervention.
