A Guide to Shock Therapy and How to Prepare

For many, the term shock therapy still carries a heavy stigma rooted in outdated portrayals of mental health treatment. But today’s version known medically as electroconvulsive therapy (ECT) is a refined, safe, and often highly effective option for people facing severe mental health conditions that haven’t responded to traditional treatments.

Whether you're exploring ECT for yourself or a loved one, understanding what it is, how it works, and how to prepare can help remove the mystery and fear.

What Is Shock Therapy (ECT)?

Electroconvulsive therapy (ECT) is a medical procedure that uses a brief electrical current to stimulate the brain while the patient is under general anesthesia. It’s typically used to treat:

• Major depressive disorder (MDD)

• Bipolar disorder (especially during manic or depressive episodes)

• Schizophrenia, particularly when medication fails

• Catatonia, a condition involving movement and speech disruptions

• Severe agitation in dementia

Although the precise mechanism isn’t fully understood, ECT appears to influence brain chemistry by increasing the availability of mood-regulating neurotransmitters like serotonin and dopamine, and may even promote the formation of new neural pathways.

When Is ECT Used?

ECT is generally considered when first-line treatments like antidepressants or mood stabilizers haven’t worked, or when symptoms require immediate intervention, such as in cases of suicidal ideation or severe psychosis.

Here’s how effective ECT has been shown to be:

• 79% of people with depression and psychotic symptoms responded to ECT

• 75% of those in a manic state due to bipolar disorder showed improvement

• 50% of individuals with schizophrenia resistant to medication improved when ECT was added

• 80–100% of those with catatonia respond positively to ECT

• 88% of people with dementia-related agitation saw symptom relief

How ECT Is Performed

A typical course of ECT involves 6 to 12 sessions, usually administered 2–3 times per week over several weeks.

Here’s what a session looks like:

1. You arrive at the treatment facility having fasted (usually after midnight the night before).

2. A nurse and anesthesiologist prepare you for general anesthesia and administer a muscle relaxant.

3. Electrodes are placed on your scalp in specific locations.

4. A brief electrical pulse triggers a seizure that lasts less than one minute.

5. After the procedure, you’ll wake up in a recovery area and be monitored for a short period most people can go home within an hour.

Thanks to anesthesia and muscle relaxants, you won’t feel the seizure or have uncontrolled physical movements during the session.

How to Prepare for Shock Therapy

Preparation for ECT is generally straightforward, but you’ll need to follow your healthcare provider’s specific instructions:

• No food or drink after midnight before your session

• Avoid smoking the day of the treatment if advised

• Review your medications with your doctor some may need to be paused

• Arrive with clean, dry hair and no styling products

Since anesthesia is involved, arrange for someone to drive you home after each session.

Side Effects and Safety

Modern ECT is considered very safe, especially compared to earlier versions of the treatment. Still, side effects can occur, most of which are temporary:

• Headache

• Nausea or grogginess

• Short-term memory loss

• Confusion after waking up

Long-term memory issues can happen, though they’re less common and often resolve over time.

Who Should Avoid ECT?

ECT isn’t appropriate for everyone. People with the following conditions may face higher risks:

• Recent heart attack, heart failure, or arrhythmias

• History of aneurysm

• Pheochromocytoma (a rare hormone-secreting tumor)

• Recent bone fractures

ECT is also not typically recommended for depression linked solely to anxiety or personality disorders unless other severe symptoms are present.

The use of ECT in children is controversial due to ethical concerns and the ability to provide informed consent, although some studies support its effectiveness in rare cases.

Final Thoughts

Despite its dramatic reputation, modern shock therapy is a well-regulated, evidence-based medical treatment that can bring rapid relief to people facing life-threatening psychiatric conditions. While it’s not the first line of treatment, it can be a critical option when other methods fall short.

If you or a loved one is struggling with severe depression, bipolar disorder, or another mental health condition that hasn’t improved with medication, ECT may offer a path forward one backed by decades of clinical use and continuing innovation.
