To study the clinical effects of Taohong Siwu Decoction with cognitive function on recovery of dysfunction in stroke patients.Methods:A total of 98 patients with cognitive impairment treated in Department of Rehabilitative Medicine in Huizhou Muncicipal Central People's Hospital from November 2014 to October 2016 were selected and divided into observation group (50 cases) and control group (48 cases) according to the random drawing method.The control group was treated with cognitive rehabilitation exercise.Based on the same treatment,the observation group was given Taohong Siwu Decoction.The data of HAMD score,MMSE score,Fugl-Meyer score and Barthel index in both groups before and after the treatment were compared.Results:After treatment,the HAMD score of the observation group was significantly lower than that of the control group.The plasma viscosity,erythrocyte backlog,whole blood high shear viscosity and low blood viscosity of the control group were significantly higher than the observation group.The MMSE score,Fugl-Meyer Score and Barthel index of the observation group were significantly higher than the control group.The total effective rate of the control group was 64.6%,while the total effective rate of the observation group was 88.0%.The effective rate of the observation group was significantly higher than the control group,and the difference between the two groups was statistically significant (P<0.05).Conclusion:For patients who had stroke with cognitive impairment,Taohong Siwu Decoction with cognitive function exercise can effectively improve the clinical symptoms.
