EurekAlert -- In a study appearing in the new issue of BRAIN STIMULATION, scientists report that a new form of electroconvulsive therapy (ECT) is just as effective as older forms in treating depression but without any of the cognitive side effects found in the older forms. In the NIMH-sponsored study, Dr. Harold Sackeim and colleagues from Columbia University randomly assigned 90 depressed patients to either right sided or bilateral ECT, using either a traditional electrical pulse or a newer “ultrabrief pulse”, and measured clinical response and cognitive side effects.
