Effects of ECT given two vs. three times weekly.

The benefits and side effects of electroconvulsive therapy (ECT) given two vs. three times per week were examined in depressed inpatients. Twenty subjects were randomly assigned to one of two treatment conditions (unilateral ECT two or three times weekly). Examiners without knowledge of treatment condition rated depression and psychiatric status and administered tests of memory and visual-motor problem solving; subjects also provided self-ratings of depression. Measures were collected before treatment and 2 and 4 weeks after treatment began. Both schedules of treatment produced significant and equivalent improvements in psychiatric symptomatology, but visual memory impairment was significantly lower in the twice-weekly group.
