Results of a large study showed that electroconvulsive therapy (ECT) might be equally effective in both patients with unipolar depression and those with bipolar depression.1

Results of a large study showed that electroconvulsive therapy (ECT) might be equally effective in both patients with unipolar depression and those with bipolar depression.1

In this randomized, double-masked, controlled trial, which included 220 patients, 170 had unipolar depression and 50 had bipolar depression. Almost all patients had not responded to treatment with multiple trials of medication.

Remission was defined as a total score of 10 or less using the 24-item Hamilton Rating Scale for Depression (HAM-D) and a 60% reduction of score from baseline. Patients received ECT 3 times weekly. While no minimum or maximum number of ECT sessions was set, patients who discontinued treatment before 10 sessions were considered to be dropouts.

In all patients studied, the remission rate was 61.8%. A reduction in HAM-D scores of at least 50% was shown in 78.8% of patients with unipolar depression and 80% of patients with bipolar depression.

The authors concluded that guidelines for the treatment of unipolar and bipolar depression minimize the role of ECT. Based on the results of this study, they encourage physicians to consider the efficacy of ECT when treating patients with unipolar depression and bipolar depression. They also suggest that treatment algorithms should be modified.
