lüll Nonpharmacological, somatic treatments of depression: electroconvulsive therapy and novel brain stimulation modalities Eitan R; Lerer BDialogues Clin Neurosci 2006[]; 8 (2): 241-58Until recently, a review of nonpharmacological, somatic treatments of psychiatric disorders would have included only electroconvulsive therapy (ECT). This situation is now changing very substantially. Although ECT remains the only modality in widespread clinical use, several new techniques are under investigation. Their principal indication in the psychiatric context is the treatment of major depression, but other applications are also being studied. All the novel treatments involve brain stimulation, which is achieved by different technological methods. The treatment closest to the threshold of clinical acceptability is transcranial magnetic stimulation (TMS). Although TMS is safe and relatively easy to administer, its efficacy has still to be definitively established. Other modalities, at various stages of research development, include magnetic seizure therapy (MST), deep brain stimulation (DBS), and vagus nerve stimulation (VNS). We briefly review the development and technical aspects of these treatments, their potential role in the treatment of major depression, adverse effects, and putative mechanism of action. As the only one of these treatment modalities that is in widespread clinical use, more extended consideration is given to ECT Although more than half a century has elapsed since ECT was first introduced, it remains the most effective treatment for major depression, with efficacy in patients refractory to antidepressant drugs and an acceptable safety profile. Although they hold considerable promise, the novel brain stimulation techniques reviewed here will be need to be further developed before they achieve clinical acceptability.|Brain/physiopathology/*radiation effects[MESH]|Deep Brain Stimulation/*methods[MESH]|Depressive Disorder/*therapy[MESH]|Electroconvulsive Therapy/*methods[MESH]|Humans[MESH]|Physical Therapy Modalities[MESH]|Transcranial Magnetic Stimulation/methods[MESH]|Vagus Nerve/physiopathology/radiation effects[MESH] |
