Background & Aim: Electroconvulsive therapy (ECT) is a highly effective treatment for affective and schizophrenic disorders. The main objective of this study was to examine the cognitive effects of ECT in patients with major depressive, bipolar and schizophrenia disorders. Methods: In this study we administered a battery of cognitive tasks on 90 patients with major depressive, bipolar and schizophrenia disorders, one day before and after the termination of ECT. The effects were measured by a set of computerized cognitive tests including: auditory reaction time, visual reaction time, verbal memory, Benton visual memory, Wisconsin card sort and motor function. The collected data were analyzed using One-way ANOVA and dependent t-test. Results: The results showed that depressive patients had poorer verbal memory and motor function after the termination of ECT compared to pretest, but their executive function was improved (p<0.05). After the termination of ECT the verbal and visual memory and executive function was significantly improved in patients with bipolar and schizophrenia disorders but their motor function was significantly reduced (p<0.05). Conclusion: Results of this study showed improvement for most cognitive functions in patients after electroconvulsive therapy. Findings of this study may help patients and their families to overcome their fear of electroconvulsive therapy. The results also can aware patients regarding the cognitive effects of electroconvulsive therapy.
