Summary

We administered an extensive battery of primarily non-memory neuropsychological tasks to 37 patients with endogenous depression, randomly assigned to either bilateral (B/ECT) or unilateral (U/ECT) electroconvulsive therapy. Testing was done prior to therapy and again shortly after the sixth induced seizure. The two groups did not significantly differ in cognitive impairment, either before or after treatment, and within-group cognitive changes following treatment were small. We conclude that neither B/ECT nor U/ECT substantially worsen non-memory cognitive performance in depressed patients, yet both result in significant clinical improvement.
