Cognitive effects of brief and ultrabrief pulse bitemporal electroconvulsive therapy: a randomised controlled proof-of-concept trial.

This study suggests there may be a small cognitive advantage in giving bitemporal ECT with an ultrabrief pulse when dosage is increased to match the efficacy of brief pulse bitemporal ECT, but the study was underpowered to fully examine this issue.Clinical Trials Registration: www.clinicaltrials.gov, NCT00870805.
