Abstract: OBJECTIVE To investigate the influence of scalp acupuncture treatment on cognitive dysfunction and brainstem auditory evoked potential on children with cerebral palsy. METHODS 40 cerebral palsy patients with cognitive dysfunction were recruited and randomly divided into treatment group (20 cases using scalp acupuncture treatment and comprehensive rehabilitation training) and control group (20 cases only using comprehensive rehabilitation training). After a course of therapy， Gesell developmental scales and brainstem auditory evoked potential of both groups were statistically analyzed. RESULTS Gesell developmental scales was in a statistically significant difference compared with before in both groups (P<0.01， P<0.05). The wave PL， IPL andⅤwave response threshold were improved significantly. There was significant difference between two groups after treatment (P<0.05).CONCLUSION Scalp acupuncture treatment is more effective than rehabilitation training alone in improving cognitive dysfunction of cerebral palsy， and it can effectively improve the abnormal BAEP.
