ABSTRACT

Objective To observe the effect of modified electroconvulsive therapy combined with venlafaxine on cognitive function and its efficacy in patients with depression.Methods 60 patients with depressive disorder were selected,and they were randomly divided into study group and control group according to the random number table method,30 cases in each group.The patients in the study group accepted modified electroconvulsive therapy for 10 times combined with venlafaxine sustained-release tablets treatment,while the patients in the control group were only treated with venlafaxine.Both two groups were treated for 6 weeks.The cognitive function was assessed by the Repeat able Battery for the Assessment of Neuropsycholgical Status (RBANS) and the therapeutic effect was evaluated by Hamilton Depression(HAMD) Scale before and after treatment.Results The scores of immediate memory,delayed memory,speech function,visual breadth and attention of both two groups after treatment were significantly higher than those before treatment(all P ＜ 0.05),and the attention score of the study group was (109.96 ± 19.01) points,which was higher than (100.32 ± 17.13)points of the control group (t =2.062,P ＜ 0.05).The HAMD scores after treatment in both two groups were significantly lower compared with those before treatment (all P ＜ 0.05),and the HAMD score of the study group was (7.23 ± 4.19)points,which was lower than (10.27 ± 5.99)points of the control group (t =2.273,P ＜ 0.05).The total effective rate of the study group(96.7％) was significantly higher than that of the control group (86.7 ％) (x2 =6.546,P ＜ 0.05),and the cure rate of the study group (60.0％) was also higher than that of the control group (36.7％) (x2 =10.901,P ＜ 0.05).Conclusion Modified electroconvulsive therapy combined with venlafaxine treatment can effectively improve the cognitive function of depressive patients,and its effect is significantly better than monotherapy.
