Physical treatments for bipolar disorder: A review of electroconvulsive therapy, stereotactic surgery and other brain stimulation techniques

Background e pharmacological advances, bipolar disorder continues to be difficult to treat. This article reviews the evidence base for the use of electroconvulsive therapy (ECT) and other brain stimulation therapies in bipolar disorder. s idence base for the efficacy of ECT and transcranial magnetic stimulation in the treatment of mania, bipolar depression and mixed affective states was reviewed. Reports on the use of vagus nerve stimulation, stereotaxic surgery, deep brain stimulation, magnetic seizure therapy and transcranial direct current stimulation in treating depression, as well as bipolar disorder were also reviewed. Studies were identified from Medline and Embase database searches. s are a few randomized controlled trials of ECT in mania and bipolar depression, and none in mixed affective states. Nevertheless, such studies consistently reported clinically meaningful efficacy, with a majority of pharmacotherapy resistant patients responding to ECT. Evidence for the use of other brain stimulation therapies in treating bipolar mood states is preliminary and limited. sions an effective treatment for acute mania, bipolar depression and mixed affective states and has useful efficacy even in pharmacotherapy-resistant patients. Other brain stimulation techniques may have potential for the treatment of bipolar disorder and should be further researched.
