Deep TMS (Transcranial Magnetic Stimulation) therapy is a non-invasive brain stimulation treatment primarily used for depression and other mental health conditions. Deep TMS therapy uses electromagnetic coils placed on the scalp to generate magnetic pulses. These pulses pass through the skull and induce small electrical currents in targeted brain regions. The magnetic fields penetrate deeper into the brain compared to traditional TMS, reaching areas up to about four to five centimeters beneath the skull.
The magnetic pulses stimulate neurons in specific brain areas associated with mood regulation, particularly the prefrontal cortex. Sessions typically last 20 to 30 minutes and are conducted five days a week for four to six weeks. Patients sit in a chair while wearing a specialized H-coil helmet that delivers the magnetic pulses. They remain awake and alert throughout, and can return to normal activities immediately after. TMS therapy for mental health works by helping to regulate neurotransmitters like serotonin and dopamine, and promoting neuroplasticity, which is the brain’s ability to reorganize and form new neural connections.
What Is Deep TMS Therapy?
Deep TMS therapy is an FDA-cleared treatment that uses a specialized helmet-like device containing electromagnetic coils. These coils generate magnetic pulses that penetrate deeper and broader areas of the brain compared to standard TMS, reaching structures involved in mood regulation and other brain functions. The “deep” in Deep TMS refers to its ability to reach brain structures further below the skull surface, accessing areas that traditional TMS cannot effectively reach.
Deep TMS is primarily approved for:
- Major depressive disorder, especially treatment-resistant depression
- Obsessive-compulsive disorder (OCD)
- Smoking cessation
It’s also being studied for anxiety disorders, PTSD, bipolar disorder, and other conditions.
Key Features
- Non-invasive: No surgery, anesthesia, or sedation required
- Outpatient procedure: You sit comfortably in a chair during treatment
- No systemic side effects: Unlike medications, it doesn’t circulate through your body
- Targeted: Stimulates specific brain regions associated with your condition
How Is Deep TMS Different From Traditional TMS Therapy?
While both use magnetic stimulation to treat brain conditions, there are several vital differences between Deep TMS and traditional TMS. Traditional TMS uses a figure-eight coil that stimulates brain tissue about 1.5 to 2 centimeters below the skull surface, primarily targeting the outer cortex. Deep TMS therapy utilizes an H-coil that penetrates up to four to five centimeters deep, allowing access to deeper brain structures, such as the anterior cingulate cortex and insula, which are more challenging to reach with traditional TMS.
Traditional TMS stimulates a more focused, localized area of the brain, much like a narrow beam of light. Deep TMS covers a broader volume of brain tissue simultaneously, stimulating wider neural networks in a single session. Both TMS treatments for depression are FDA-cleared, but Deep TMS has additional approvals for OCD and smoking cessation, partly due to its ability to reach the deeper brain regions involved in these conditions.
Traditional TMS sessions typically last between 20 and 40 minutes, with protocols tailored to specific conditions. Deep TMS sessions typically last around 20 minutes and may require fewer total sessions for certain situations; however, standard courses are generally similar in duration. The sensations are similar, though some patients find the helmet design of Deep TMS more comfortable than having a coil manually positioned against their head throughout the session.

Which Mental Health Conditions Can Deep TMS Help Treat?
Deep TMS has been studied and used for various mental health conditions, with varying levels of evidence and FDA approval. Here’s the breakdown:
FDA-Approved Conditions
Major Depressive Disorder (MDD)
- Particularly effective for treatment-resistant depression when antidepressants haven’t worked
- The most established use of Deep TMS
Obsessive-Compulsive Disorder (OCD)
- FDA-cleared in 2018 for adults with OCD
- Targets brain regions involved in compulsive behaviors
Smoking Cessation
- Approved to help reduce cigarette cravings
- Stimulates areas involved in addiction and impulse control
Conditions Being Actively Researched
Anxiety Disorders
- Generalized anxiety disorder (GAD)
- Panic disorder
- Social anxiety disorder
- Showing promising results in clinical studies
Post-Traumatic Stress Disorder (PTSD)
- Targets trauma-related brain circuits
- Research is ongoing with encouraging outcomes
Bipolar Disorder
- Used cautiously for bipolar depression
- Requires careful monitoring
Addiction and Substance Use Disorders
- Cocaine dependence
- Alcohol use disorder
- Other substance addictions
Eating Disorders
- Anorexia nervosa
- Binge eating disorder
Other Conditions Under Investigation
- Chronic pain syndromes
- Tinnitus
- Alzheimer’s disease and cognitive decline
- Schizophrenia
- Autism spectrum disorder
Deep TMS is typically considered when the first-line treatments haven’t been sufficient or medications cause intolerable side effects. The Transcranial Magnetic Stimulation success rate works best as part of a comprehensive treatment plan that may include therapy and other interventions.
Why Is Deep TMS Considered a Non-Invasive Brain Stimulation Therapy?
Deep TMS therapy is classified as non-invasive because it stimulates brain tissue without requiring any surgical procedures, incisions, or physical penetration of the skull or skin. The treatment works entirely through the external application of magnetic fields generated by electromagnetic coils housed in a helmet placed on the patient’s head.
Unlike invasive brain stimulation methods, such as deep brain stimulation (DBS), which require the surgical implantation of electrodes or devices into the body, Deep TMS delivers therapeutic effects. At the same time, the patient sits comfortably in a chair.
There’s no need for anesthesia, and patients can immediately return to their normal daily activities after each session. The magnetic pulses pass harmlessly through the skull and scalp to reach the targeted brain regions, leaving no physical marks and requiring no healing process.
The non-invasive nature of Deep TMS also means it avoids the systemic side effects associated with psychiatric medications, as nothing is introduced into the bloodstream or digestive system. The treatment’s effects are localized to specific brain regions, and the most common side effects are mild and temporary, such as slight scalp discomfort or headache at the stimulation site.
The non-invasive process makes Deep TMS an attractive option for patients who cannot tolerate medication side effects or who prefer to avoid pharmacological interventions. The procedure’s safety profile, combined with its ability to modulate brain activity without direct surgery, positions Deep TMS as a middle ground between talk therapy and more invasive interventions, offering a powerful therapeutic tool that respects the body’s integrity while providing direct neurological benefits.
Key Takeaways on Deep TMS Therapy
- Deep TMS therapy is a non-invasive treatment that uses electromagnetic coils in a helmet-like device to generate magnetic pulses that stimulate specific brain regions involved in mood regulation.
- The key advantage of Deep TMS over traditional TMS is its ability to access deeper brain structures.
- The treatment has received FDA clearance for treating major depressive disorder.
- Patients remain awake, require no anesthesia or recovery time, and can resume normal activities immediately.
- Deep TMS serves as an alternative for patients who haven’t responded to traditional therapy or medications, or who want to avoid medication side effects.
