ECT for Schizophrenia: Effectiveness, Treatments, Side Effects

When most people hear “electroconvulsive therapy,” or ECT, they picture an
old black-and-white movie scene with dramatic electricity, wild hair, and a
lot of screaming. Modern ECT for schizophrenia could not be more different:
it’s done under anesthesia, carefully monitored, and usually offered only
when other treatments haven’t done the job. It’s more lab coat than horror
movie.

Still, ECT is a serious medical procedure. If you or someone you love is
living with schizophrenia, you may be wondering whether ECT is safe,
whether it helps, and what the real side effects look like in everyday
life. Let’s break down what the research actually says about
effectiveness, how treatment works in practice, and what to weigh before
saying yes or no.

Schizophrenia 101: Why Treatment Can Be So Challenging

Schizophrenia is a long-term brain disorder that affects how a person
thinks, feels, and experiences reality. Common symptoms include
hallucinations (like hearing voices), delusions, disorganized thinking, and
changes in motivation and social connection. It usually begins in late
teens or early adulthood and often requires lifelong treatment.

Standard treatment starts with antipsychotic medications, plus
psychosocial support like therapy, family education, and help with work,
school, and daily life skills. For many people, this combination keeps
symptoms manageable.
But not everyone responds. Some continue to have severe hallucinations or
delusions, become very withdrawn, or develop catatonia (when a person
becomes very still, rigid, or stuck in repetitive movements). In these
harder-to-treat situations, specialists sometimes look at “brain
stimulation therapies” such as ECT.

What Exactly Is ECT?

Electroconvulsive therapy is a medical procedure that uses a brief,
controlled electrical current to trigger a short seizure in the brain while
the person is under general anesthesia. The seizure usually lasts less than
one minute, and the whole appointment often takes less than an hour.

Here’s what usually happens during an ECT session:

• You fast for several hours beforehand, similar to other procedures done with anesthesia.
• In the treatment room, you’re connected to monitors that track heart rate, blood pressure, and brain activity.
• An anesthesiologist gives you medicine through an IV so you fall asleep, plus a muscle relaxant so your body doesn’t move much during the seizure.
• The psychiatrist places electrodes on your head (on one side or both) and delivers a carefully measured electrical pulse.
• You wake up in a recovery area, usually within 10–20 minutes, often feeling groggy or a bit confused at first.

ECT is typically given two to three times a week for several weeks.
A “course” of treatment may include 6–12 sessions or sometimes more,
depending on how someone responds.

When Do Doctors Consider ECT for Schizophrenia?

For schizophrenia, ECT is not a first-line treatment and is never
meant to replace antipsychotic medications. Instead, major guidelines and
expert reviews suggest ECT as an add-on option for specific situations:

• Treatment-resistant schizophrenia: when a person has tried multiple antipsychotics at adequate doses and durations but still has severe symptoms.
• Clozapine-resistant schizophrenia: when symptoms remain disabling even after trying clozapine, the “go-to” medication for tough-to-treat cases.
• Severe, life-threatening psychosis: such as intense suicidal thinking, refusal of food or fluids, or extreme agitation and aggression.
• Catatonia: ECT is one of the most effective treatments for catatonia, which can occur in schizophrenia.
• Schizoaffective disorder or overlapping mood symptoms: when severe depression or mania is present along with psychosis, ECT may be considered, especially if other treatments have failed.

Some guidelines, such as those from the UK’s NICE, explicitly say that ECT
should not be used for routine, ongoing management of
schizophrenia. Instead, it’s reserved for short-term use in very severe or
treatment-resistant cases, and always in combination with medication, not
as a stand-alone therapy.

How Effective Is ECT for Schizophrenia?

The short answer: ECT can help some people with schizophrenia, especially
those with severe, treatment-resistant symptoms or catatoniabut the
evidence is mixed, and it’s not a magic switch that works for everyone.

What the Research Shows

Older and more recent reviews suggest that ECT, when added to
antipsychotic medications, can lead to meaningful improvement in
treatment-resistant schizophrenia. Some studies report better overall
symptom control, faster reductions in hallucinations and delusions, and
shorter hospital stays.

A Cochrane review looking at randomized controlled trials in
treatment-resistant schizophrenia also found that ECT plus medication can
be more effective than medication alone in reducing psychotic symptoms,
though the quality of the evidence and study sizes vary.

On the flip side, more recent sham-controlled trials have raised questions.
A 2024 double-blind study in people with chronic treatment-resistant
schizophrenia found no clear difference between real ECT and sham (fake)
ECT on core schizophrenia symptoms, suggesting that ECT may not help every
subgroup equally.

When you put it all together, the current picture looks like this:

• Most likely to help: severe acute psychosis, catatonia, and cases where a person hasn’t responded to multiple medications.
• Less clear benefit: long-standing negative symptoms like low motivation, emotional flatness, and social withdrawal; research here is mixed and still evolving.
• Not a cure: even when ECT helps, people typically still need ongoing antipsychotic treatment and psychosocial support.

How Fast Does It Work?

One of ECT’s biggest advantages is speed. While antipsychotic medications
can take weeks or months to reach full effect, ECT often produces changes
over a few treatmentssometimes within one to three weeks. For someone who
is extremely distressed, suicidal, or not eating or drinking, that speed
can be life-saving.

What an ECT Treatment Plan Looks Like

Before ECT is even on the table, a psychiatrist should:

• Review all past medications, doses, and how long they were tried.
• Rule out medical problems that might be worsening symptoms.
• Confirm that schizophrenia (or a related condition) really is the correct diagnosis.

If ECT is recommended, you can expect a structured plan:

• Pre-treatment work-up: physical exam, blood tests, heart tests (like an EKG), and sometimes brain imaging to make sure the procedure is as safe as possible.
• Electrode placement: unilateral (one side of the head) or bilateral (both sides). Newer “hybrid” methods aim to balance effectiveness with fewer memory problems.
• Course length: often 6–12 treatments, 2–3 times per week. Some people need more sessions; others may benefit from occasional “maintenance” ECT to prevent relapse.
• Combination approach: ECT is almost always used alongside antipsychotic medication, not instead of it.

During the course, the treatment team regularly checks symptom scales,
memory and thinking, mood, sleep, and day-to-day functioning. If benefits
don’t show up after a reasonable number of sessions, the team may decide
to stop or adjust the approach.

Side Effects of ECT: The Good, the Bad, and the Foggy

Common Short-Term Side Effects

Right after a session, it’s very normal to feel a bit off. Common
short-term side effects include:

• Headache or pressure in the head
• Nausea or upset stomach
• Muscle soreness or jaw pain
• Temporary confusion or feeling “foggy”
• Feeling tired for the rest of the day

These effects usually fade within hours, and many people can resume light
activities later that day, though driving and important decision-making are
typically off-limits for a while.

Memory and Thinking Changes

Memory concerns are the side effects people worry about the most, and for
good reason. ECT can cause:

• Short-term memory problems: trouble remembering events shortly before or after treatments.
• Retrograde amnesia: “gaps” in memory for past events. This can sometimes include personal memories in the months before treatment.
• Processing speed issues: feeling mentally slower or less sharp for a period of time.

Many people see gradual improvement in memory over weeks to months after
treatment stops. However, some report lasting gaps or cognitive changes,
and recent surveys suggest that more types of side effectslike emotional
blunting and cardiovascular symptomsmay occur more often than previously
recognized.

Medical Risks

Because ECT is done under anesthesia and briefly stresses the heart and
brain, there are medical risks, especially for people with serious heart,
lung, or neurological conditions. These can include:

• Changes in heart rhythm or blood pressure during the procedure
• Very rare prolonged seizures
• Complications from anesthesia (like breathing difficulties)

A thorough medical evaluation beforehand is critical. For many people,
especially those without major medical problems, ECT is considered
relatively low riskbut “low risk” never means “no risk.”

Who Should Be Cautious About ECT?

ECT may not be appropriateor may require extra precautionsfor people
who have:

• Unstable or serious heart disease
• Recent stroke or certain brain abnormalities
• Severe uncontrolled high blood pressure
• Certain high-risk pregnancy situations

Ultimately, it’s a case-by-case decision. A psychiatry team, often
together with a cardiologist or neurologist, will weigh the potential
benefits of symptom relief against the medical and cognitive risks.

Questions to Ask Before Saying Yes to ECT

If ECT is on the table, it’s absolutely okay to ask detailed questions.
Here are a few to bring to your next appointment:

• Why are you recommending ECT instead of adjusting medications or trying another option?
• What specific goals are you hoping ECT will achieve (less hallucinations, less catatonia, better mood, etc.)?
• How many treatments do you expect I’ll need, and how will you decide whether it’s working?
• What are the biggest risks for someone with my medical history?
• How will you monitor my memory and thinking during and after the course?
• What happens if I want to stop ECT partway through?
• What supports (therapy, skills training, family education) will be in place along with ECT?

A good treatment team will welcome these questions and answer them in
clear, straightforward language. If you feel rushed or pressured, it’s
appropriate to slow things down and ask for a second opinion.

So, Is ECT “Worth It” for Schizophrenia?

ECT for schizophrenia sits in a complicated middle ground. On one hand,
research and clinical experience show that it can be an effective
add-on treatment for people with severe, treatment-resistant symptoms,
especially when there is catatonia, life-threatening psychosis, or
overlapping mood episodes.

On the other hand, ECT is far from perfect. It doesn’t work for everyone,
it can cause meaningful memory and cognitive side effects, and recent data
suggest that some adverse effects may be more common than earlier studies
reported.

At the end of the day, ECT is not about “last resort punishment” or
“shocking someone into behaving.” It’s one toolsometimes a powerful one
in a larger treatment toolkit that includes medications, therapy, social
support, and recovery-oriented services. For the right person, at the right
time, with the right safeguards, ECT can make a dramatic difference. For
others, it may not be the right fit.

The most important step is thoughtful, shared decision-making: you, your
family or support network, and your care team weighing the real-world
benefits and risks together.

Real-Life Experiences with ECT for Schizophrenia (Composite Stories)

The research tells us what ECT can do on average. Stories help us
understand how it can feel in real life. The experiences below are
fictional composites based on common patterns clinicians and patients
describe; they’re not real individuals, but they reflect real-world
themes.

Story 1: “Everything Was Frozen” ECT for Catatonia

Alex was in his early 20s when his schizophrenia symptoms spiked
dramatically. He stopped speaking, stopped eating, and often sat in the
same position for hours. His eyes were open, but it was like he was frozen
in place. Medications that had helped in the past weren’t doing much this
time, and every day his parents grew more terrified.

The hospital team diagnosed catatonia, a serious condition that can happen
in schizophrenia. After trying medications without much improvement, they
recommended ECT. The word alone scared Alex’s parents, but the psychiatrist
explained the procedure in detail, answered questions about memory and
safety, and made sure they understood that ECT would be paired with
antipsychotic medication and ongoing support.

After the first few treatments, Alex began moving more. He started shifting
in his chair, then following simple directions, then speaking a few words.
By the end of a 10-treatment course, he was eating on his own, walking
around the unit, and even joking (dryly) about the hospital food. His
parents felt like they were “getting him back.”

Alex did notice that his memory for the hospital stay was patchy; entire
weeks felt like a blur. Over the next several months, some memories came
back, while others stayed fuzzy. He and his parents agreed that while the
memory gaps were frustrating, the improvement in catatonia and psychosis
was worth the trade-off. They also felt strongly that having clear
information and frequent check-ins made the process less frightening.

Story 2: “Some Things Got Better, Some Didn’t” ECT for Treatment-Resistant Symptoms

Maria, in her 30s, had lived with schizophrenia for over a decade. She had
tried multiple antipsychotics, including clozapine. While her hallucinations
were less intense, they never fully went away, and she struggled with low
motivation and social withdrawal. Her psychiatrist suggested a trial of ECT
to see if it could nudge her symptoms further in the right direction.

During the ECT course, Maria noticed that her most distressing voices were
quieter and less commanding. She felt less overwhelmed and more able to
follow a daily routine. Her mother noticed she was spending more time in
the living room instead of isolating in her bedroom.

But the change wasn’t dramatic across the board. Maria still found it
hard to feel pleasure or enthusiasm. The “flatness” in her emotions
didn’t suddenly vanish. She also had some memory gaps around family events
that had happened in the months before treatment, which upset her.

In the end, Maria decided ECT had helped in specific waysmainly by
dialing down the loudest, most intrusive psychotic symptomsbut it
wasn’t a full reset. She and her treatment team focused next on
cognitive-behavioral strategies, structured daily routines, and social
skills groups to build on the gains ECT had provided.

Story 3: “We Needed Hope” A Family Perspective

James’s parents had watched him cycle in and out of the hospital for years.
Every time, new meds were tried, some progress was made, and then another
severe episode hit. When a new psychiatrist suggested ECT, his parents felt
two emotions at once: hope and dread.

They worried about memory loss and long-term side effects. They also
worried about doing nothing and watching James continue to struggle. The
hospital’s ECT team took time to walk them through the evidence, explain
how risks are monitored, and acknowledge the limits of the researchboth
the reassuring parts and the controversial ones.

After several weeks of treatment, James’s hallucinations were less
intense, and he was more engaged in conversations. His parents noticed that
he laughed again, something they hadn’t heard in months. At the same time,
they saw him struggle to recall details of recent family events. They found
themselves gently reminding him of stories and moments he couldn’t quite
place.

For this family, ECT was neither miracle nor disaster. It was a tool that
opened the door to more stability and made other treatments easier to use.
The experience also taught them that asking questions, insisting on
regular updates, and staying involved in decisions made them feel less like
bystanders and more like partners in James’s care.

sapo:
Electroconvulsive therapy (ECT) has come a long way from its movie-villain
image, but it’s still one of the most misunderstood treatments in mental
health. For people living with severe, treatment-resistant schizophrenia,
ECT can sometimes provide faster relief from intense hallucinations,
delusions, or catatonia than medication aloneand, in some cases, it can
be life-saving. At the same time, it’s a major medical procedure with real
side effects, especially around memory and thinking, and it doesn’t work
for everyone. This in-depth guide explains how ECT is used in schizophrenia
today, what the research actually shows about effectiveness, the most
common short- and long-term side effects, and the key questions to ask
before making a decision. You’ll also find real-world composite stories
that show what ECT can look like for patients and families navigating some
of the toughest moments of serious mental illness.
