Abstract Objective： To investigate and contrast accuracy of MoCA scale and MMSE scale assessment of elderly patients with cognitive function. Method： 85 elderly patients who could be independent and matched with the completion of energy meter in our hospital were selected from March 2013 to April 2014，the patients were given MMSE scale and MoCA scale detection and the scores were recorded， two scale detection of cognitive impairment situation were compared. Result：57 cases（ 67.06%） with cognitive impairment in MoCA scale，30 cases（ 35.29%） with cognitive impairment in MMSE scale， 28 patients with normal cognition were coincident in the evaluation of MoCA scale and MMSE scale，but the evaluation of MMSE scale for cognitive impairment patients accounted in MoCA scale only 52.63%， the difference was statistically significant（P<0.05）.In MoCA scale determination， compared the visual space and executive function，naming， attention， language， abstract， delayed recall and directional of the case group and control group， the differences were statistically significant（P<0.05）. Conclusion： The cognitive function of elderly patients with decrease in different degree， evaluation scale MoCA result compared to the MMSE scale results is more accurate，it can provide more objective results to assess cognitive dysfunction，it’s worthy of clinical popularization and application.
