The clinical data and CT scan analysis of vascular dementia(Report of 50 cases)

Objective: To investigate the characterization of vascular dementia in the pathogenesis, clinical data and CT scan. Methods: The diagnosis of vascular dementia is according to the DSM - Ⅲ - R and Hachinski Ischemic Score. We investigated the intelligence, clinical data and CT scan on fifty patients of vascular dementia caused by ischemic cerebral vascular disease. Results: VD patients were accompanyed with cerebral arteriosclerosis for 100%, bypertension for 78% and hyper lipidemia for t52% respectively. In addition, there are directional and count disturbance for 88%. CT scan was detected in 50 cases with VD and 141 infarct lesions were discovered (left 79 and right 62).Conclusion:The main feature of VD is the memory reduced. The major risk factors of VD are cerebral arteriosclerosis and hypertension. The occurrence of VD is relating to the white matter low attenuation and the valume,num - ber, position of the infarction.
