rTMS for Depression (MDD)

Repetitive Transcranial Magnetic Stimulation (rTMS) is considered an important treatment option in Major Depressive Disorder (MDD) when the brain has not responded adequately to previous medication treatments, or when antidepressant side effects are not tolerated. It is not necessarily intended for a first “mild” depressive episode, but it is an approved medical intervention for more complex clinical situations.

During the assessment stage, the psychiatrist reviews your history in detail in order to determine whether your depressive profile, with or without accompanying anxiety, is suitable for neuromodulation treatment.

1. When rTMS is indicated

rTMS has been officially approved by the FDA since 2008 specifically for Major Depressive Disorder. The clinical indication is stronger when a patient has received one or two classes of antidepressant medication for an adequate period of time, such as SSRIs or SNRIs, without achieving full remission of symptoms.

Many patients experience depression with prominent anxiety features, known as anxious depression, which can make pharmacotherapy more difficult. In clinical practice, rTMS may be adapted through specific protocols, such as bilateral rTMS, to address both depressed mood and anxiety symptoms. If you have tried medication extensively without sufficient benefit, your condition may be clinically described as “treatment-resistant” — read our dedicated guide to rTMS in Treatment-Resistant Depression (TRD).

2. Which patients may be candidates?

A likely candidate for rTMS in depression may:

• Feel that medication no longer lifts the “fog” or the feeling of sadness.
• Experience significant side effects from medication, such as weight gain, sedation, or sexual dysfunction.
• Have prominent anhedonia, meaning a marked loss of pleasure in things previously enjoyed.
• Have no non-removable metallic objects in the head, such as aneurysm clips, and no active history of epilepsy.

3. How rTMS fits into an overall treatment plan

You do not necessarily need to stop medication or psychotherapy in order to receive rTMS. In most cases, magnetic stimulation works as an adjunctive treatment. The magnetic pulses “activate” specific networks in the prefrontal cortex, helping the brain become more responsive again. As sessions progress, and if symptoms improve, the physician may safely begin a gradual medication reduction, always under close medical supervision.

4. What to expect in practice

Magnetic treatment for depression is an outpatient procedure. The typical pathway is:

• After a detailed assessment, the clinician decides whether to use classic rTMS or the faster iTBS protocol.
• Usually, 15 to 30 sessions are scheduled, often on a daily basis. Learn more about cost and procedure.
• Sessions last from 3 to 37 minutes and take place while you sit comfortably in the clinic chair.
• Immediately after each session, you return to normal life, including driving and work, without dizziness or sedation.
