Abstract

Objectives: Electroconvulsive therapy (ECT) is a well-established treatment for mood disorders in younger adults and has been consistently shown to be safe and effective in unipolar depression in older adults. However, data on this treatment in older adults with bipolar disorder are limited. In this retrospective study, we report outcomes from all cases of older adults with bipolar depression who received ECT from a large academic institution over a 7-year period.

Methods: We retrospectively identified all patients 65 years and older with bipolar depression who were treated with ECT over a 7-year period. Patients receiving ECT for an episode of bipolar depression were included in the study based on chart review and availability of documented outcome measures. Primary outcomes were changes in Montreal Cognitive Assessment and Clinical Global Impressions scores.

Results: We identified 34 patients meeting inclusion criteria. Collectively, patients had statistically significant improvement in Montreal Cognitive Assessment scores and reductions in Clinical Global Impressions severity scores after treatment. Pre- and posttreatment Montgomery-Asberg Depression Rating Scale scores were also available for a subset of 20 patients and demonstrated a similarly significant reduction in severity with treatment. There were no serious adverse effects of treatment, and no patients discontinued treatment.

Conclusions: Electroconvulsive therapy was well tolerated and effective in treating bipolar depression in older adults. Importantly, these findings challenge commonly held worries about cognitive decline in older adults receiving ECT. It should be a regular consideration for management of this challenging illness in a population that may otherwise not respond to pharmacotherapy.
