TMS for depression device
How TMS Treats Obsessive-compulsive disorder

Transcranial magnetic stimulation (TMS) uses a targeted pulsed magnetic field, similar to what is used in an MRI machine to deliver magnetic pulses to the area of the brain with weakened neurotransmitter activity causing anxiety, compulsive and obsessive thinking which can result in OCD.

In August 2018, the FDA cleared the Brainsway DeepTMS (dTMS) device for OCD. Special coils were developed to target the areas in the brain affected by OCD to stimulate those areas safely and efficiently at greater depths.

What you can expect from a TMS Therapy session

During the TMS procedure, the patient wears a padded helmet which activates the magnetic pulses. These repeated magnetic wave pulses reach the areas of the brain which are affected, stimulating the weakened neurotransmitters of the brain affecting OCD.


This procedure is a safe alternative to traditional ways of treating common mental illnesses. There are no side effects by TMS as with traditional medications. Unlike MRI, TMS magnetic waves produce no radiation, and the TMS technician is in room with the patient the entire time during treatment.
During treatment of TMS, doctors and technicians can control the intensity of these pulses based on the response of the patient. All patients are awake during the TMS treatment. The procedure does not need the patient to be given any anesthesia.

Side Effect

Patients can finish treatment and then go about their regularly scheduled day, driving home, going to work, etc. with no downtime or residual side effects. For the procedure to be most successful, patients need to receive magnetic stimulation for short periods of time, daily, over 4-6 weeks. The sessions typically last around 10-20 minutes. Symptoms often noticeably start being alleviated 1-2 weeks after treatment begins.


What is the difference between regular TMS and dTMS?

Standard TMS, sometimes called RepetitiveTMS (rTMS) delivers magnetic pulses to the brain by figure-8 coils. These older coils are limited in how far the magnetic waves can penetrate. DeepTMS (dTMS) a newer technology developed and patented by Brainsway Ltd, uses three-dimensional coils in a helmet design.

What are the advantages of dTMS?

Its advantage lies in its combined ability to encompass a broader surface area of the brain stimulating deeper structures more directly within the brain, and to more efficiently target those crucial structures which are linked to mood control and mental health conditions.

Does dTMS work for OCD?

Studies have shown that approximately half the medication-resistant patients who were provided TMS treatment for OCD showed significant improvement in their symptoms. Brainsway’s dTMS system is currently the only system on the market that is cleared by the FDA to treat OCD and anxious depression.

What is the difference between TMS treatments for depression and OCD?

The procedures are relatively similar. Different parts of the brain are targeted for depression and for OCD. Brainsway Ltd has developed different helmets with unique and patented coil structures to be able to target these different areas.
