TMS for OCD: How Deep TMS Works for Treatment-Resistant OCD
By Lance Demaline • June 26, 2026
Quick Answer: Deep TMS is a non-drug, non-invasive treatment that uses magnetic pulses to reach brain circuits involved in OCD, and it's FDA-cleared specifically for obsessive-compulsive disorder. It's generally used for people whose OCD hasn't responded enough to standard treatments like SSRIs and exposure therapy — not as a first step. At Optimum in Columbus, OCD treatment uses BrainsWay Deep TMS over a course of daily sessions. Here's how it works, who it's for, and how it fits alongside the treatments you may have already tried.
If you've worked through medication and therapy for OCD and still feel stuck, you're in the group this treatment was designed for. OCD is notoriously persistent, and "treatment-resistant" doesn't mean untreatable — it means the first-line options haven't been enough on their own. Deep TMS is one of the routes clinicians turn to at that point, and it works differently from anything you'll have tried so far.
What Deep TMS for OCD is
Deep TMS (transcranial magnetic stimulation) uses focused magnetic pulses to stimulate areas of the brain involved in mood and behavior. It's delivered through a cushioned helmet you wear while seated — there's no medication, no anesthesia, and no surgery.
The version used for OCD is specifically FDA-cleared for that condition. Optimum delivers it using BrainsWay Deep TMS, a system whose OCD coil is designed to reach deeper and broader brain regions than a standard TMS setup. That OCD-specific clearance matters: not every TMS device or protocol is cleared for OCD, and the one used here is.
How it works for OCD specifically
OCD isn't the same target as depression, and the treatment reflects that. The brain circuits involved in obsessive-compulsive symptoms run through regions including the medial prefrontal cortex and anterior cingulate cortex — areas linked to the loop of intrusive thoughts and compulsive responses. Deep TMS for OCD is aimed at those circuits rather than the area targeted in depression treatment.
There's also a step that surprises people. In the OCD protocol, a brief, personalized symptom provocation is often used right before stimulation — you're guided to briefly bring an OCD trigger to mind so the relevant circuits are active when the pulses are delivered. The idea is to stimulate the network while it's "switched on." Your clinician will explain exactly how this works in your case.
Who it's for
Deep TMS for OCD is generally considered for adults with treatment-resistant OCD — meaning OCD that hasn't improved enough after standard approaches. In practice, that usually means you've tried:
- One or more SSRIs (the first-line medications for OCD), and
- Exposure and response prevention (ERP), the gold-standard form of OCD therapy
And you still have symptoms that interfere with your life. It's not a first move, and it's not a replacement for those treatments. It's an option for when they haven't gotten you far enough.
Whether you're a candidate depends on your history and a clinical evaluation. Some conditions and medical factors make TMS a poor fit, which is part of what that evaluation sorts out.
What a session and a course look like
A single session is short and undramatic. After any symptom-provocation step, you sit while the device delivers pulses for a set period — you're awake and aware the whole time, and you can drive yourself home and return to your day afterward. There's no sedation and no recovery period.
OCD treatment isn't one session, though. It's a course of daily sessions over several weeks. At Optimum, the OCD course runs to 29 sessions. Consistency matters — the course is designed to be completed as a series, not picked up and dropped.
Still weighing your options?
A quick consultation answers more than another hour of reading.

Side effects and safety
Deep TMS is generally well tolerated. Because nothing enters your bloodstream, it avoids the systemic side effects that medications can cause — no weight changes, no sexual side effects, no daily-pill fog.
The most common side effects are mild and tend to ease after the first sessions, including:
- Headache
- Scalp discomfort or tingling at the treatment site
- Lightheadedness
Serious side effects are rare. As with any TMS, there's a very low risk of seizure, which your provider screens for during your evaluation. If you've had seizures or have certain implanted metal devices, tell the clinic — these are part of the safety screening.
What it costs and whether insurance covers it
Coverage for OCD TMS is less consistent than it is for depression TMS, and it depends heavily on your specific plan. The most reliable way to know is to have Optimum verify your benefits before you start, rather than relying on a general figure.
If you're paying out of pocket, Optimum's self-pay rate for the OCD course is $10,500 for the full 29-session series, and CareCredit financing is available. Confirm the current figure and your coverage during your consultation, since what you actually pay depends on your plan.
How Deep TMS fits with your other OCD treatment
This is worth being clear about: Deep TMS doesn't replace ERP or medication, and the best OCD care is usually a combination rather than a single tool. ERP remains the most established psychotherapy for OCD, and many people continue therapy and medication alongside TMS. Think of Deep TMS as another instrument in the plan for OCD that's been hard to budge — not a reset button. Your provider will help you fit it into what you're already doing.
Is TMS for OCD the same as TMS for depression?
No. They target different brain regions and use different protocols, and the OCD version includes a symptom-provocation step that depression treatment doesn't. The device used for OCD is also specifically FDA-cleared for it.
Do I have to stop my OCD medication to do TMS?
Usually not. Many people continue their medication alongside Deep TMS. Any change to your medications is a decision to make with your provider, not on your own.
Does it hurt?
Most people describe a tapping sensation on the scalp rather than pain. Some scalp discomfort or a headache is common early on and tends to settle as you get used to it.
How long before I might notice a difference?
There's no fixed timeline, and responses vary from person to person. OCD often responds gradually rather than overnight, which is part of why the full course matters. Your provider will track your progress with you.
Can I do TMS if ERP didn't work for me?
That's a common reason people consider it. Deep TMS for OCD is aimed at exactly this group — people whose OCD hasn't responded enough to first-line treatments. An evaluation will confirm whether it's a fit.
