What Is the Difference Between TMS and ECT?
TMS uses magnetic pulses to gently stimulate brain regions linked to mood, while ECT uses electrical currents to trigger a brief, controlled seizure. Both treat severe depression, but the mechanisms, side effects, and patient experience differ sharply.
How TMS Works
TMS therapy delivers focused magnetic pulses through a coil placed against the scalp. The pulses activate underactive neurons in the dorsolateral prefrontal cortex, the brain region tied to mood regulation.
Sessions last 20 to 40 minutes, 5 days a week, for 4 to 6 weeks. Patients sit awake in a chair, receive no medication or sedation, and drive themselves home afterward. Our deep TMS uses Brainsway H-coil technology to reach 3 to 5 centimeters into the brain, deeper than the figure-8 coils used in many clinics. We also use Magnaventure TMS technology, which allows us to offer a second advanced treatment option alongside BrainsWay.
How ECT Works
ECT delivers a controlled electrical current to the brain, inducing a brief seizure lasting 30 to 60 seconds. Patients receive general anesthesia and a muscle relaxant during each session, and they must arrange transportation home.
Treatment typically requires 6 to 12 sessions, usually 3 times per week. Sessions take place at a hospital with an anesthesia team on hand. Recovery time after each session ranges from 30 minutes to several hours, during which most patients cannot work or drive.
What Are the Side Effects of TMS vs ECT?
Side effect profiles differ significantly. ECT carries higher risk and requires recovery time.
TMS Side Effects
Patients undergoing TMS typically report:
- Mild scalp discomfort at the treatment site
- Brief tension headaches after sessions
- Tingling in facial muscles
- No memory, cognitive, or alertness effects
ECT Side Effects
ECT can cause:
- Short-term memory loss
- Confusion lasting hours after each session
- Headache, jaw pain, and muscle soreness
- Anesthesia-related risks
Most memory effects fade within weeks, but some patients report lasting gaps for events near the treatment period.
How Effective Is TMS Compared to ECT?
ECT remains the most effective acute treatment for severe, life-threatening depression, with response rates of 70 to 90% percent. TMS shows response rates of 80 percent, with about half of all patients reaching full remission, based on our two-year patient outcomes review.
TMS often serves as a first-line interventional treatment because of its safer profile. ECT is typically reserved for cases where rapid response is critical or other treatments have failed.
Who Should Consider TMS Instead of ECT?
TMS is the better fit for adults who want a noninvasive option without anesthesia, memory effects, or hospital stays. Good TMS candidates include patients who:
- Have not responded to one or two antidepressant trials
- Cannot tolerate antidepressant side effects
- Need to keep working and driving during treatment
- Want to avoid general anesthesia
For patients weighing medication alternatives, our TMS vs antidepressants breakdown compares the two options directly.
Does Insurance Cover TMS and ECT?
Both TMS and ECT are FDA-approved and typically covered by insurance for treatment-resistant depression. Coverage usually requires documentation of failed antidepressant trials.
Our team handles insurance verification before treatment begins, including TRICARE for military members and veterans.

Outpatient Psychiatry for Medication Review
If you are still on an antidepressant during treatment, our outpatient psychiatry team coordinates medication adjustments alongside TMS sessions.
How Long Do Results Last?
TMS results often last 6 to 12 months after a full treatment course. Patients who relapse can receive maintenance sessions to extend the benefit without restarting from scratch.
ECT results can fade within 6 months, and many patients require ongoing maintenance ECT every 2 to 4 weeks to prevent relapse. Maintenance ECT carries the same anesthesia and memory considerations as the initial course.
