Abstract: Objective:To probe the effects of the electroacupuncture on vascular dementia and its P₃₀₀.Methods:60 patients suffering from vascular dementia were randomly divided into two groups,the electroacupuncture group(30 cases) and the medicine group(dihydroergotoxine,DHET,30 cases).Changes in scoring value of HDS-R(Hasegawa Dementia Scale),FAQ(Functional Activity Questionaire),ADL,injure of nerve function,main symptoms and P₃₀₀ were observed before and after treatment.The course was 42 days.Results:The results was that effective rate was 60% in electroacupuncture group and 23.33% in medicine group(P<0.01).All the above indices were improved in electroacupuncture group,better than those of medicine group(P<0.05～0.01).Conclusion:It suggests that the electroacupuncture therapy can promote the VD patients in intelligence,functional activity,ability of daily living and quality of life.
