Short- and long-term evaluation of cognitive functions after electroconvulsive therapy in a Japanese population.

Aim: While electroconvulsive therapy (ECT) is a well-established, safe, and effective treatment for mental illnesses, the potential for adverse effects on cognitive functions remains controversial. We aimed to evaluate multiple cognitive functions in different time periods before and after ECT in a Japanese population.

Methods: A battery of five neurocognitive tests was administered to patients who underwent a course of ECT treatment at three time points: before, immediately after, and 4 weeks after ECT.
