TMS for OCD: How It Helps Treat Obsessive-Compulsive Disorder

With thoughts that won’t stop, rituals that take hours, and overwhelming anxiety, those living with obsessive-compulsive disorder (OCD) are consumed by mental traps and exhausting routines. While many people may find relief through medications or therapy, these treatments don’t work for everyone. As a result, innovative treatments, like transcranial magnetic stimulation (TMS), are gaining traction for treatment-resistant cases of OCD. 

Here’s what you need to know about TMS for OCD and how it’s helping people have more control over their obsessions and compulsions. 

What is OCD?

OCD is a mental health condition that affects between 1% and 3% of people worldwide. While many people occasionally double-check if they locked the door, OCD is more serious and disruptive in one’s day-to-day life. 

OCD creates a cycle that’s hard to break. First come unwanted thoughts (obsessions) that cause extreme anxiety. Then come repetitive behaviors (compulsions) that are done to reduce this anxiety. The problem is these behaviors only provide temporary relief, which reinforces the cycle. Many people with OCD spend hours trapped in these cycles, making it difficult to work, maintain relationships, or handle basic tasks.  

OCD Obsessions and Compulsions

As previously mentioned, OCD can be broken into obsessions and compulsions. Obsessions are unwanted thoughts, images, or urges that repeatedly enter your mind against your will. Rather than worries about real problems, these thoughts are constant, intrusive, and stressful. 

Common obsessions include: 

  • Fear of germs, contamination, or getting sick
  • Worry about harming yourself or others
  • Unwanted sexual or religious thoughts
  • Need for symmetry, exactness, or things being “just right”
  • Excessive doubt about safety
  • Fear of losing control or acting on impulses

These thoughts often go against a person’s true character. For example, a loving parent might have intrusive thoughts about harming their child, or a religious person might experience blasphemous thoughts they find horrifying. 

After experiencing an obsession, a person with OCD will engage in compulsive behaviors to reduce their anxiety and neutralize their thoughts. Common compulsions include: 

  • Excessive cleaning or hand washing
  • Checking things repeatedly (locks, appliances, switches)
  • Counting, tapping, or repeating certain words
  • Arranging items in specific patterns or orders
  • Mental rituals like silent prayers or counting
  • Seeking constant reassurance from others
  • Performing actions until they feel “just right”

In addition to these behaviors, some people with OCD will practice avoidance. Someone with contamination fears might avoid public restrooms, or a person with harm obsessions might not drive for fear of hitting someone. 

How is OCD Typically Treated? 

First-line treatments for OCD are exposure and response prevention (ERP) and medication. ERP is a subtype of cognitive behavioral therapy in which you confront the thoughts, images, or situations that trigger your obsessions (exposure) while learning not to perform your usual compulsions (response prevention). Unlike talk therapy, ERP requires active participation in and outside of sessions.

For medication, doctors will prescribe: 

  • Clomipramine (Anafranil): The first medication proven effective for OCD and still considered to be more effective than sertraline, fluoxetine, and fluvoxamine 
  • SSRIs (like Prozac, Zoloft): Often prescribed at higher doses for OCD than for depression or other anxiety disorders, which can increase both effectiveness and adverse side effects

While these treatments help many people, about 40% of OCD patients don’t respond to standard treatments. This leaves treatment-resistant individuals looking for alternative options to address their OCD symptoms.  

What is TMS? 

TMS is a non-invasive brain treatment that uses magnetic fields to stimulate certain areas of the brain. Unlike more invasive procedures, TMS doesn’t require surgery, anesthesia, or recovery time. 

During a TMS session, an electromagnetic coil is placed against your scalp near targeted brain regions. The coil then delivers magnetic pulses that painlessly pass through your skull to stimulate brain cells. 

How Does TMS Help OCD?

Research shows that OCD involves dysfunction in the: 

  • Prefrontal cortex (involved in decision-making)
  • Anterior cingulate cortex (helps regulate emotions and behavior)
  • Striatum (involved in various cognitive functions)
  • Thalamus (relays sensory information)

Brain imaging studies have shown that these regions show unusual activity patterns in people with OCD. When OCD symptoms flare up, activity in these areas increases, whereas when symptoms improve with treatment, activity decreases. 

TMS is able to directly target these overactive brain circuits. For instance, high-frequency (20 Hz) deep TMS that specifically targets the medial prefrontal cortex and anterior cingulate cortex has been proven to normalize the activity levels in these regions.   

TMS Efficacy in Treating OCD

Research on TMS for OCD shows promising results. In one study, researchers found impressive response rates with deep TMS:

  • 72.6% of patients showed initial improvement
  • 52.4% maintained this improvement over time
  • For patients who completed a full course of 29 sessions, the response rate was 57.9%

Another trial that compared deep TMS to a placebo treatment found that: 

  • Patients receiving actual TMS treatment showed nearly twice the symptom reduction compared to those receiving the placebo (6.0 point vs 3.3 point reduction on the YBOCS scale)
  • The response rate for active treatment was 38.1% compared to just 11.1% for the placebo group
  • Benefits continued or improved after treatment ended, with response rates reaching 45.2% at one-month follow-up

Both studies used the Yale-Brown Obsessive-Compulsive Scale (YBOCS) to evaluate symptom improvement. A reduction of 6 points may not sound dramatic, but in clinical terms, this can mean significant relief from symptoms that have continued despite multiple treatment attempts.  

Is TMS Safe for OCD Treatment?

TMS has gained a lot of attention for its strong safety profile. In 2017, the FDA approved a specific repetitive TMS (rTMS) for OCD treatment due to its efficacy and safety. 

Multiple studies have confirmed that TMS is generally well-tolerated with no serious side effects in most patients. The most common side effects are mild and temporary: 

  • Mild headache 
  • Discomfort at the treatment site
  • Jaw pain
  • Facial or scalp muscle twitching

Seizures are sometimes mentioned as a concern with TMS, but they are extremely rare, occurring in less than 1% of patients. Importantly, TMS has been safely used even in patients with conditions that might seem higher risk, including those with epilepsy, traumatic brain injuries, and those who previously experienced a TMS-related seizure (with appropriate precautions).  

Who Should Not Receive TMS? 

While TMS is safe for most people, certain factors may disqualify you from treatment. You should not receive TMS therapy for OCD if you have: 

  • A history of seizures or certain neurological conditions (though exceptions may be made with proper medical supervision)
  • Metal implants in or near your head (except for dental fillings)
  • Electronic implants controlled by physiological signals, like pacemakers or vagus nerve stimulators
  • Metal fragments, shrapnel, or bullet fragments above your neckline

During an initial consultation, your provider will review your medical history in detail to determine if TMS is right for you.
