AIM: To explore the relationship between acupuncture therapeutic method and the cognizing potential P300 of AD patients. METHODS AND RESULTS: We introduced P300 into the studying area for AD, and found the N2, P3 latent period evidently prolonged and amplitude reduced significantly in AD patients compared with the control group. The research affirmed that acupuncture could excite the cognizing potential P300 for AD patients. CONCLUSION: P300 could be an effective measure for the diagnosis and evaluation of AD treatment.
