Sixty-two cerebral traumatic patients were randomly divided into two groups: acupuncture group (32 cases) and physiotherapy group (30 cases). The changes of mini-mental status examination (MMSE) scores and auditory evoked potential P₃₀₀ were observed before and after treatment. Results: the markedly effective rate and the total effective rate of the acupuncture group were 46.9% and 81.3% respectively, which were significantly higher than that of 10.0% and 30.0% of the physiotherapy group (P < 0. 01). It was found that after treatment the above-mentioned indexes in the acupuncture group changed significantly (P<0.05~0.001), while in the physiotherapy group they were not (P> 0.05). The therapeutic effect in acupunctrue group was better than that in physiotherapy group (P < 0.001). The results confirmed that the cognitive function of cerebral traumatic dementia patients was enhanced effectively after acupuncturing Houxi (SI3) and Shenmen (HT7).
