| Popis: | 98 With the advancement of medical technology, the older population aged 65 or more of Taiwan has already reached 7% threshold defined by United Nations to become an aging nation. In recent years, the population of Taiwan is aging rapidly, according to the latest statistics by the Ministry of Interior at the end of 2008, the older population has reached 2.4 million, accounting for 10.4% of the total population. A Taiwanese Dementia Society survey revealed that the prevalence of dementia in old age is about 5-6%. However, Alzheimer''s Dementia is ranked the first, whereas Vascular Dementia is the second. Increased prevalence of multiple variables with increase age is presented. In this study, Mini-Mental State Examination (MMSE) is the major research tools and using DSM-IV as an assist to classifity Alzheimer''s Dementia and Vascular Dementia. Using logistic regression, classification and regression tree and support vector machine to analysis the different between Alzheimer''s Dementia and Vascular Dementia. The results were shown that, Logistic regression using the difference between the five variables and no difference by adding the four variables to construct the model accuracy were 0.6991 and 0.6372; classification and regression tree (CART) for the 0.6903 and 0.7168; support vector machines (SVM) for the 0.7345 and 0.9027. From the results, revealed that support vector machine model performed the best accuracy all three models. |
