Objectives: The objective is to evaluate the pattern of cognitive deficits after electroconvulsive therapy (ECT); to ascertain the role of various psychosocial, illness and treatment-related parameters on cognitive functions after ECT; and to evaluate the effect of donepezil on various cognitive deficits.
Materials and methods: A triple-blind randomized controlled trial was undertaken. Ninety patients undergoing ECT were included into study after due consent and institutional ethical approval. They were randomized into two groups: one using donepezil with ECT and the other using placebo with ECT. Various cognitive parameters were studied before ECT, after a course of ECT and after 4 weeks of last ECT. Findings were assessed in the light of available socialdemographic and clinical parameters and existing literature.
Results: ECT was found to be an effective therapeutic modality. Immediate memory worsened over the course of ECT till after 4 weeks of ECT. Augmentation of donepezil was found useful. It sped up the improvement of general memory and working memory during ECT.
Conclusion: Donepezil has therapeutic and prophylactic benefit on cognition of patients undergoing ECT over the course of treatment till 4 weeks after the ECT.
