4 Differences Between TMS Therapy and ECT For Depression

When you’re researching treatment for depression, it’s likely that two acronyms frequently come up: TMS and ECT. These stand for transcranial magnetic stimulation and electroconvulsive therapy. Many people consider these treatments after medications and traditional therapies haven’t provided enough relief.

Both TMS and ECT are FDA-cleared options for certain forms of depression. However, they differ significantly in how they work, what treatment feels like and who they’re best suited for. By learning about the key differences between the two, you can collaborate with your health care provider to determine which option should be incorporated into your treatment plan.

Read on to learn the basics about TMS and ECT before we break down the key differences.

What are TMS therapy and ECT?

Let’s start by comparing the basics.

TMS therapy is a noninvasive treatment that uses magnetic pulses to stimulate specific brain regions involved in mood regulation. TMS targets the dorsolateral prefrontal cortex (DLPFC) and the anterior cingulate cortex (ACC), areas of the brain associated with depression and emotional processing.

TMS is FDA-approved for major depressive disorder, including treatment-resistant depression as well as treatment-resistant depression with anxious features (anxious depression).

ECT, or electroconvulsive therapy, uses controlled electrical currents to intentionally trigger a brief seizure while the patient is under general anesthesia. It’s meant to “reset” the neuronal pathways that contribute to depression symptoms.

ECT is an older treatment option that’s been used for decades, dating back to 1938, and is typically reserved for severe depression, especially when rapid improvement is needed.

4 key differences between TMS therapy and ECT for depression

We want you to feel confident discussing your options with your provider so that you can advocate for your wellness. Here are four key differences between TMS and ECT to keep in mind when you’re considering depression treatments:

How the treatment works in the brain

TMS: targeted stimulation

TMS uses magnetic pulses to stimulate underactive areas of the brain involved in depression. The pulses activate specific neuronal networks and encourage healthier patterns of brain activity.

ECT: controlled seizure activity

ECT works by delivering electrical currents that produce a brief, controlled seizure. This seizure activity appears to alter brain chemistry in ways that can rapidly reduce severe depressive symptoms.

While both treatments affect brain function, TMS is more targeted, whereas ECT affects broader brain regions.

Anesthesia and invasiveness

TMS: awake and outpatient

TMS therapy sessions don’t require anesthesia or sedation.

Here’s what to expect during treatment:

You remain awake and alert
You sit comfortably in a treatment chair
You can drive yourself home afterward

Because anesthesia isn’t used, there isn’t a recovery period required, allowing you to immediately return to your regular routine.

ECT: performed under general anesthesia

ECT requires general anesthesia and muscle relaxants during sessions. You’ll also have medical monitoring in a hospital or surgical setting.

After each session, you need time to recover and will need someone to drive you home. For many patients, this difference plays a major role in the TMS therapy versus ECT decision.

Side effects and cognitive impact

Side effects are often one of the biggest concerns when considering advanced depression treatments. Even though both TMS and ECT come with possible side effects, they can vary in severity and duration.

TMS is generally well-tolerated. There are possible temporary side effects that are mild and manageable, including scalp discomfort, headaches and tingling during treatment. TMS doesn’t cause memory loss or cognitive impairment. Patients remain mentally sharp throughout the course of treatment.

ECT can be highly effective, especially for severe depression. However, there are potential side effects, including:

Short-term memory loss
Confusion after treatment
Possible longer-term memory changes in some individuals

While many patients recover cognitive function over time, memory-related side effects are a key distinction when comparing TMS therapy versus ECT.

Treatment schedule and time commitment

TMS and ECT both involve sessions that take place several times per week for multiple weeks.

TMS: consistent outpatient sessions

A standard TMS course at PTC includes:

36 sessions
Five days per week
Over six to eight weeks

Each TMS session typically lasts 10 to 20 minutes. Since it doesn’t require anesthesia, you can return to normal activities immediately afterward.

ECT: fewer sessions, more recovery

ECT is often administered two to three times per week for several weeks. Although the total number of sessions may be fewer, each treatment requires anesthesia and recovery time. Some patients may need time away from work during the treatment period.

When weighing TMS therapy versus ECT, consider how each option fits your daily responsibilities and lifestyle.

Psychiatry Treatment Centers uses TMS therapy for depression

Even though ECT can be the right choice for some people, TMS therapy is an effective option for people who haven’t experienced improvement in their depression symptoms after trying medication.

At PTC, we provide deep TMS therapy using Brainsway devices that help 81.6% of people with depression symptoms have a positive response, and 65.3% achieve remission.

TMS also provides a lower risk of severe side effects and quicker recovery than ECT.
