Electroconvulsive Therapy (ECT)

Reviewed by the HeyPsych Medical Review Board

Board-certified psychiatrists and mental health professionals

Indications

Primary Indications

Severe, treatment-resistant depressionUrgent need for rapid symptom control (e.g., suicidal intent)Bipolar disorder with severe depressive or manic episodesCatatonia or severe psychosis

Mechanism

ECT's exact mechanism is not fully understood. The induced seizure is believed to cause changes in brain chemistry, neurotransmitter systems, and connectivity patterns, leading to mood stabilization and symptom reduction.

Protocol

Preparation

Pre-treatment evaluation including medical history, physical exam, ECG, and anesthesia clearance.

Procedure

Patient placed under general anesthesia with muscle relaxant.
Electrodes positioned on scalp (bilateral or unilateral placement).
Brief electrical stimulus delivered to induce a controlled seizure.
Patient monitored until recovery from anesthesia.

Frequency: Typically 2–3 times per week

Duration: 2–4 weeks for acute course

Total Treatment Time: 6–12 treatments per acute course

Equipment

ECT device with adjustable electrical stimulus parameters
EEG monitoring equipment
Anesthesia equipment and medications

Session Structure

Pre-Session

Anesthesia induction and monitoring setup.

Treatment Phase

Electrical stimulus delivery and seizure monitoring.

Post-Session

Recovery in monitored setting; assessment for side effects.

Expected Outcomes

Long Term

Maintenance therapy may be required to prevent relapse

Cost Considerations

typical session cost: $300–$800

total treatment cost: $3,000–$9,000 for a standard acute course

insurance coverage: Often covered for severe depression or catatonia

Special Populations

Clinical Notes

Bilateral placement is more effective but has greater cognitive side effect risk.
Continuation or maintenance ECT may be needed to prevent relapse.
Memory loss is usually transient but may be persistent for events near treatment period.
