ABSTRACT
So far, in Viet Nam, there aren't systematic research on the role of psychological and imaging tests for diagnosis of AD. Objectives: To study the role of brain MMSE and CT findings in diagnosis of AD. Methods: 35 patients with AD were diagnosed according to criteria of ICD.10 and DSM.4; Descriptive, prospective and followed up investigation was applied. Results: MMSE could be used for all patients (100%), MMSE scores coresponded with dementia severity. Reduction in scores more than 3 points per year presented in 93.3%. On CT, general atrophy of brain presented in 100% patients, temporal lobe atrophy was seen in 65.7% of patients. The difference of brain atrophy level has been significant at all patients after 2.5 to 3 years follow up. Conclusion: MMSE was considered as appropriate test to measure dementia severity and to define AD. On CT, great speed of brain atrophy after 2.5 to 3 years follow up could confirm diagnosis of AD.
