The utility of SNSB-II for the comparison of cognitive function of dementia patients with Alzheimer's disease dementia, vascular dementia and Parkinson's disease

Objective : The purpose of this study was to compare the cognitive function of dementia patients with Alzheimer's disease dementia, vascular dementia and Parkinson's disease using SNSB-II and to investigate the performance differences of three types of dementia patients in five cognitive domains: attention, language, visual-spatial, memory, and frontal-executive function. Methods : The three groups consisted of 393 patients with Alzheimer's disease, 153 patients with vascular dementia, and 26 patients with Parkinson's disease. The differences in performance between the three groups were compared through ANOVA, and Bonferroni adjustment was conducted when significant differences were found. Results : As a result of the analysis, there was no difference in the five cognitive domains of the three groups, but some individual subtests showed differences in the performance variables reflecting the cognitive characteristics of each group: The score of verbal memory recognition was lower in the Alzheimer's disease dementia group than in the Parkinson's disease dementia group, and executive function, planning and control ability, which are frontal lobe functions, were higher in the vascular dementia group and the Parkinson's disease dementia group than in the Alzheimer's disease dementia group. Conclusion : The differences among neuropsychological performance variables of three types of dementia patients, the usefulness of SNSB-II as an assessment tool for dementia, limitations of the study, and points to be considered in follow-up studies were discussed.
