Abstract
The present study was conducted to examine the differences and correlations between verbal fluency and story comprehension according to the working memory(WM) capacity, and to find out what WM factors influence the linguistic competence in Alzheimer's disease(AD) and vascular dementia(VaD) groups each consisting of 15 patients. The results of their performance produced firstly significant differences in phonemic fluency, story comprehension, delayed recall and recognition task between the two groups. Further analysis shows that VaD group had significant correlations between the scores of story comprehension and the recognition test scores additionally. These findings suggest that it is possible to differentiate the two groups even by story comprehension tasks and WM. In conclusion, the clinical application of the results is likely to contribute to appropriate treatment plans and effective interventions for elderly with AD and VaD as well as to improve the classification criteria for both types of dementia.
