Objective:Observe the curative effects of transcutaneous electrical stimulation (TES) combined with medicine when it is used to treat the multi-infarct dementia (MID). Method: 54 dementias are randomly divided into two groups: The group TES and the matched group

with each 27 patients

in which

the group TES adopts TES with medicine and the matched group is only supplied to medicine. Score the MMSE

MBI and HDS before and after treatment. Judge the curative effects according to the scores of MBI. Results: In comparison

the MMSE

MBI and HDS are greatly different

the curative efficiency of the group tES is higher than the one of the matched group and the difference is significance in statistic(P<0.05 ).Conclusion: TES can be used to MDI and can function as healing brains.
