Abstract
Purpose of Review
In this review, the efficacy and safety of FDA-approved neuromodulation devices (electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), and vagus nerve stimulation (VNS)), as well as emerging neuromodulation treatments currently under investigation.
Recent Findings
ECT is the “gold standard” somatic therapy for treatment-resistant depression (TRD). Although the clinical benefits are outweighed by potential cognitive and cardiovascular side effects in a majority of cases, it remains unfairly stigmatized. TMS has few cognitive or somatic side effects but is not as effective as the treatment of psychotic depression or more treatment-resistant depression in elders. VNS has limited data in older patients but has been shown to be effective in chronic, treatment-resistant adults. Several investigative neuromodulation treatments including magnetic seizure therapy (MST), focal electrically administered seizure therapy (FEAST), transcutaneous VNS (tVNS), transcranial direct current stimulation (tDCS), and deep brain simulation (DBS) shown promise in geriatric TRD.
Summary
ECT, TMS, and VNS are effective treatments for late-life depression, and research has continued to refine the techniques. Investigative neuromodulation techniques are promising, but evidence for the safety and efficacy of these devices in the geriatric population is needed.
