Electroconvulsive Therapy

Ascension Seton Shoal Creek offers a wide range of psychiatric treatment options and services, including electroconvulsive therapy (ECT). ECT is a safe and effective treatment for many psychiatric illnesses. ECT is most frequently used in major mood disorders such as major depressive disorder and bipolar disorder. Studies show ECT is faster and is more broadly effective than medication in resolving acute mood episodes such as unipolar and bipolar major depression, bipolar mania, and bipolar mixed states. For this reason ECT is used primarily when patients’ symptoms are severe or when they fail to respond to medication. Many patients report improved quality of life, both short and long term, after receiving ECT.

For clinical questions about ECT therapy, please call us at 512-324-2034. To schedule an appointment for outpatient ECT therapy, please call 512-324-3380 or contact us online.

ECT is considered for patients with the following clinical indications:

  • Major depression (especially if accompanied by psychosis, suicidal intent, or significant neurovegetative symptoms resulting in a failure to function)
  • Bipolar disorder (ECT treats manic, depressive, and mixed episodes)
  • Schizoaffective disorder (particularly during mood episodes)
  • Schizophrenia (when symptoms are severe, include catatonic symptoms, or when medications are not sufficient)
  • Pregnant patients with mood disorders
  • Catatonic states, regardless of etiology, including malignant catatonia and neuroleptic malignant syndrome
  • Parkinson’s Disease, especially when accompanied by mood symptoms


All ECT patients require a physician referral. If you are interested in more information or if you are a physician who would like to schedule your patient for a consultation, please contact the ECT service at the Seton Mind Institute.

  • Fax: 512-324-3379

One of our doctors will perform an ECT consultation, including an extensive psychiatric evaluation, and discuss the risks, benefits, alternatives and side effects of ECT. Results of the consultation will be shared with the referring psychiatric provider. If the patient is an appropriate candidate for treatment, the doctor will arrange for the pre-ECT work-up, including medical evaluation with anesthesiology clearance, laboratory work, EKG, hospitalization (if necessary), and other diagnostic tests as needed to assure safe provision of care.

We will work closely in consultation with the primary psychiatric provider to optimize medication for the provision of ECT, and to keep the primary physician informed of the patient’s progress throughout treatment.
