Cognitive Behavioral Therapy an Effective Follow-up to ECT

While electroconvulsive therapy (ECT) is very effective treating acute depression, especially among patients who have not responded to antidepressants, relapse rates following ECT are high. Researchers have been exploring treatments that may extend the effectiveness of ECT and reduce relapses, including antidepressant medication and continuation ECT. A new study by Eva-Lotta Brakemeier and colleagues in the journal Biological Psychiatry finds that cognitive-behavioral therapy combined with medication was most effective at sustaining response to ECT.

In the study, 60 patients who responded well to three-times-per-week right unilateral ultra-brief ECT then were prescribed antidepressant medication following current guidelines for ECT followup. Of these patients, one-third were randomly assigned to receive the medications only. Another third were randomly assigned to receive the medications and continuation ECT, and the final third were randomly assigned to receive medication and participate in 15 weeks of cognitive-behavioral therapy in a group setting. Each group was observed at six months, and then at one year. The group who received medication and cognitive behavioral therapy had significantly higher response rates than the other groups at both follow-up evaluations.

After the initial treatment with ECT, 70% of the patients had responded and 47% had achieved remission. Following the six months of continuation treatment, 77% of the group that received medication and cognitive behavioral therapy responded, while only 40% of the group receiving medication and continuation ECT responded, and 44% of those receiving medication alone responded. After one year (six months following the end of treatment), response rates were 65% for those who had received medication and therapy, 28% for those who had received medication and ECT, and 33% for those who had received medication alone.

Editor’s Note: These results are striking for several reasons. As has been found in most studies, continuation ECT is not very effective at sustaining remission. Cognitive behavioral therapy with medication beats the other options hands-down. These results are in accord with others that show that cognitive behavioral therapy also helps prevent relapses in patients who responded well to medications. The take-home message is that people who respond well to antidepressant medication or ECT would do well to add cognitive behavioral therapy to their other preventive treatments.

The current study did not replicate parameters for continuation ECT that were successful in a study by Axel Nordenskjöld and colleagues in the Journal of ECT in 2013. Nordenskjöld used weekly ECT for six weeks and every two weeks thereafter, for a total of 29 ECT treatments in one year, and found this more intense regimen was more effective at preventing relapse than medication alone.
