What is TMS?

TMS, which stands for Transcranial Magnetic Stimulation, is a non-invasive treatment currently FDA approved for patients with Major Depression. TMS is an alternative treatment for when medications don’t work.

TMS uses a MRI – strength magnetic pulse to stimulate an area of the brain. In the treatment of depression, we target the Left Dorsolateral Pre-frontal Cortex (L-DLPFC), which is associated with emotional control and response.

How does TMS work?

The TMS coil is positioned on the patients scalp to target the Left Dorsolateral Pre-frontal Cortex. This part of the brain controls emotional response. Pulses are delivered in rapid succession, delivering a total of 3000 pulses per treatment session.

In the treatment of depression, TMS causes the brain cells, call neurons, to become more active and strengthen the neural connection between them. Similar to exercise, TMS “exercises” the L-DLPFC. As the L-DLPFC becomes stronger, depression is reduced.

How effective is TMS?

Up to 60% of patients respond to TMS therapy and see a decrease in their symptoms of depression. Around 25% of patients will be depression free.

What does TMS feel like?

During TMS patients will feel a rapid pulse against their forehead. TMS is not painful and  is often described as feeling like a woodpecker. When patients start their treatment, the TMS Technician will monitor the  intensity of the pulses to insure the patient’s comfort.

How long will the effects of TMS last?

The durability of TMS is often dependent on the response patients have to TMS. Those who respond well to TMS may see a decrease in response after 9 – 12 months. Here at Southeastern Psychiatric Associates, we stay in contact with our patients throughout the year to check in with them. When patients feel a increase in their symptoms of depression, it is encouraged that they contact us and they may receive TMS re-treatment.

How is TMS administered?

Transcranial Magnetic Stimulation is administered by placing the TMS coil on the patient’s scalp. Patient’s are not anesthetized and are fully conscious and aware during their treatment. Patient’s are sat comfortably in a dentist-style chair and are able to chat with the TMS Technician or friends and family, watch tv, read a book, or use an iPad during their appointment.

Who is a good candidate for TMS?

TMS therapy is an appropriate treatment for patients with Major depressive disorder and have failed to achieve satisfactory benefit from medications and therapy.
