You’ve done exposure response prevention. You’ve tried the medications, probably more than one. NeuroStar TMS therapy for OCD in Norwood, Canton, and Dedham, MA is FDA-cleared non-drug treatment when ERP and medication haven’t worked.
Percentage of patients who achieved at least a 30% reduction in YBOCS (Yale-Brown Obsessive Compulsive Scale) scores in FDA clinical trials, compared to 11% with sham treatment

Unlike SSRIs, TMS doesn’t circulate in your bloodstream—no weight gain, no sexual dysfunction, no emotional blunting
OCD isn’t liking things tidy. It isn’t double-checking the stove once. It’s a brain circuit stuck in a loop—alarm, compulsion, temporary relief, alarm again. The table below shows how that plays out day to day.
Symptom Domain
Intrusive thoughts
Compulsive washing
Checking rituals
Ordering/arranging
Counting rituals
Reassurance seeking
Mental rituals
Avoidance
Common Impact
Unwanted, repetitive thoughts about contamination, harm, symmetry, or morality that feel impossible to dismiss
Handwashing until skin cracks; excessive showering; avoiding “contaminated” surfaces
Repeatedly verifying locks, appliances, lights, or written work—sometimes dozens of times before leaving a room
Needing objects perfectly aligned; distress when things are “wrong” in a way others don’t notice
Performing actions a specific number of times; mental counting that interrupts daily activities
Asking the same question repeatedly; calling or texting family to confirm nothing bad happened
Silently repeating words or phrases; mentally undoing “bad” thoughts with “good” ones
Skipping places, people, or situations that trigger obsessions—which gradually shrinks your whole world
When these patterns consume more than an hour a day, or when you can’t stop them even though you want to. OCD has moved from annoying to disabling.
Standard OCD medications change serotonin levels everywhere. Your brain gets some benefit. So does your gut, your appetite, your sleep, and your sex drive. That’s why side effects pile up.
Transcranial magnetic stimulation for OCD works differently. No pills. No bloodstream circulation. No systemic distribution.
Here’s what actually happens.
The magnetic coil sits against your scalp. The clinician positions it over the dorsomedial prefrontal cortex (dmPFC) and anterior cingulate cortex (ACC) —regions that sit near the top-front of your brain. These areas form the hub of the OCD circuit. They’re overactive in people with OCD. Too much alarm. Too much error detection. Too much “something’s wrong here.”
The coil delivers focused magnetic pulses—about the same strength as an MRI. Those pulses induce tiny electrical currents in the targeted brain tissue. Not enough to hurt. Enough to change how neurons fire. It’s the same mechanism behind NeuroStar TMS Therapy, which is FDA-cleared for OCD. Repeated stimulation does two things: First, it calms the overactive ACC. That’s the region that fires when you feel something is “incomplete” or “wrong.” Turn down that signal, and the urgency behind the compulsion starts to fade.
Second, it strengthens the dmPFC’s ability to regulate the deeper alarm circuits. Better top-down control means the intrusive thought doesn’t automatically trigger a full-blown panic response.
One critical difference from depression TMS: OCD protocols often use symptom provocation. That means right before the magnetic pulses start, the clinician helps you briefly focus on something that triggers your OCD. A contamination thought. A symmetry urge. That activates the target circuit, making it more responsive to the stimulation that follows.
This is why TMS for obsessive-compulsive disorder works even when medications haven’t. You’re not adding another systemic chemical. You’re directly rewirig the brain circuits that generate the obsessions and compulsions.
A full course of TMS treatment for OCD requires commitment. Five days per week for six weeks. That’s roughly 30 sessions total. Each session runs between 19 and 37 minutes, plus brief provocation time at the start.
No cost. No obligation. A phone callback to discuss your OCD symptoms, what treatments you’ve already tried, and whether TMS makes sense. Call (617) 958-6036.
One of Onward Psychiatry’s board-certified Psychiatric Nurse Practitioners (Hannah Lynch, Kristin Feeley, Carly Munzer, Rebeca Gallego, or Sarah Silva) assesses your full clinical picture. They confirm OCD diagnosis, document treatment resistance, and rule out contraindications.
Onward Psychiatry offers pharmacogenomic analysis to understand how your body processes medications. This can help guide medication choices if you continue with SSRIs alongside TMS.
The clinician finds the exact spot on your scalp that controls thumb movement. That establishes your personal stimulation intensity. Then they map the dmPFC/ACC target position. The first appointment runs about 1.5 hours.
You recline in a comfortable chair. The clinician guides you through brief symptom provocation (a few seconds of focusing on an OCD trigger). Then the coil delivers pulses. You feel tapping or knocking on your scalp. You hear clicking sounds. You wear earplugs. You stay completely awake. Most patients read, scroll their phone, or listen to music. When the session ends, you get up and leave.
No sedation. No recovery room. No driving restrictions. You can go straight back to work, pick up your kids, or run errands.
The “not instant” reality – Most people don’t feel better after one session. Or five. Improvement typically builds over weeks. Some patients notice reduced urgency around compulsions by week 3 or 4. Others take the full 30 sessions before seeing meaningful change.
Maintenance sessions – After the initial 30 sessions, some patients need follow-up treatments. Weekly or monthly. Tapered gradually. Onward Psychiatry discusses maintenance planning before you finish the acute course.

Onward Psychiatry handles the paperwork. Stacy Hawking, the Office Administrator, and the TMS team verify benefits, manage prior authorizations, and explain your out-of-pocket costs before treatment starts.
The brain targets are different. Depression TMS targets the left dorsolateral prefrontal cortex (DLPFC). OCD TMS targets the dorsomedial prefrontal cortex (dmPFC) and anterior cingulate cortex (ACC). The OCD protocol also typically uses symptom provocation—briefly triggering your OCD right before stimulation—to activate the target circuit. Session length and number of pulses also differ.
Research shows benefit across contamination, checking, symmetry, and harm-related OCD. The FDA trial included mixed subtypes. That said, some people respond better than others. Your provider can discuss whether your specific symptom profile is a good fit.
Most insurers want documentation of at least two failed SSRI trials (adequate dose for 8–12 weeks each) plus a course of ERP therapy (typically 8+ sessions). Some also require a trial of clomipramine (Anafranil), a tricyclic medication specifically for OCD. Onward Psychiatry’s psychiatric evaluation assesses your treatment history formally.
Yes. Most patients continue their medications during TMS. The goal isn’t to stop your meds—it’s to add a treatment that works through a different mechanism. After TMS, some patients reduce or discontinue their SSRIs, but that’s a discussion for later.
The evidence is strongest for TMS plus ongoing ERP. TMS calms the brain circuit. ERP teaches you what to do with the remaining space. Doing only TMS may produce improvement, but combining with therapy usually yields better long-term outcomes. Onward Psychiatry offers both.
Briefly uncomfortable. The clinician asks you to focus on something that triggers your OCD—a contaminated thought, a symmetry urge, a checking impulse—for a few seconds. That activates the target circuit. Then the magnetic pulses start. The discomfort passes quickly. Most patients find it tolerable, especially once they see the results.
About 60% of treatment-resistant OCD patients don’t achieve a 30% YBOCS reduction. That doesn’t mean you’re out of options. Onward Psychiatry also offers medication management, genetic testing to guide medication choices, intensive ERP through their LICSW clinicians, and other services. Your provider will discuss next steps.
NeuroStar TMS is FDA-cleared for adolescent depression (ages 15–21), not specifically for adolescent OCD. TMS for pediatric OCD is considered off-label. That said, some research supports it. Onward Psychiatry can evaluate whether off-label TMS is appropriate for your teen based on symptom severity and prior treatment history.
Yes. Onward Psychiatry offers secure video appointments via Zoom for patients throughout Massachusetts who cannot attend in person. Initial TMS sessions must be in-person, but consultations and follow-up appointments can be done via telehealth.
