Electroconvulsive therapy (ECT) has been shown to be effective in improving depressive symptoms in the majority of patients and more effective than antidepressant medications in treating the psychotic subtype of depression. Primary indications for ECT among patients with depression are lack of a response to or intolerance of antidepressant medications, previous response to ECT, and the need for a rapid and definitive response (e.g., because of psychosis or a risk of suicide). ECT can be used in both unipolar and bipolar disorders as well as in the elderly and pregnant populations. The following questions will need to be answered in order to properly understand ECT and its role in treatment.

  • Where does ECT play a role in treatment mental illness?1-4
  • What do current psychiatric guidelines recommend?5
  • What recommendations are available for ECT use in pregnancy?6
  • What role does anesthesia play in ECT?7-8
  • How should anesthetics be chosen?9
  • What are significant drug-drug interactions with ECT and how should they be managed?10-13
  • How do psychotropic medications effect seizure threshold and how will it affect ECT?14-15
  • What are suggested augmentation strategies with ECT?16-17
  • What are recommended textbooks that may serve as good references regarding ECT?18-19
