Abstract: | The purpose of this study was to determine whether cognitive test performances alone could distinguish patients with probable Alzheimer's disease from those with probable vascular dementia. Sixty-eight outpatients with clinical diagnoses of either Alzheimer's disease or vascular dementia were administered a brief battery of neuropsychological tests. Scores from the Boston Naming Test and the Hopkins Verbal Learning Test were identified as most discriminating of the groups. Seventy-seven per cent of the sample was correctly classified by a stepwise discriminant function analysis. Results of this study indicate that selected neuropsychological tests have moderate concurrent utility in the differential diagnosis of dementia. |
