Electroconvulsive Therapy (ECT): Modern Practice, Safety & Indications

ECT has not stopped—it remains a gold-standard treatment for severe, treatment-resistant psychiatric conditions. Modern ECT bears little resemblance to historical depictions: it is administered under brief general anesthesia with muscle paralysis, using ultra-brief pulse, right-unilateral electrode placement to maximize efficacy and minimize cognitive side effects.

Current Indications (APA / NICE Guidelines)

  • Major depressive disorder (MDD) with psychotic features, catatonia, high suicidality, or failure of ≥2 adequate antidepressant trials
  • Bipolar depression or mania unresponsive to medications
  • Schizophrenia with catatonia or treatment-resistant positive symptoms
  • Neuroleptic malignant syndrome
  • Severe autism-related self-injury (selected cases)

Treatment Course

  • Acute series: 2–3 sessions/week × 6–12 treatments (individualized)
  • Continuation/maintenance ECT: weekly → biweekly → monthly to prevent relapse
  • Each session: 5–10 min procedure; 30–60 min total with recovery

Safety Profile

Informed Consent Essentials

  • Explanation of risks/benefits/alternatives (including ketamine, TMS, MAOIs)
  • Capacity assessment (may involve surrogate if impaired)
  • Documentation of voluntary consent per state law

Access & Stigma

ECT is available at most academic medical centers and many community hospitals. Stigma persists despite robust evidence; advocacy by NAMI, APA, and patient groups continues to improve access.
