Targeted Brain Stimulation For Depression

Transcranial magnetic stimulation uses an external device to deliver repetitive magnetic pulses to targeted areas of the brain without surgery. TMS treatment involves an initial clinical assessment to determine whether the person meets the relevant clinical criteria, followed by a series of scheduled treatment sessions when appropriate.

During a session, the device is positioned near the head and delivers controlled magnetic stimulation while the patient remains awake. Treatment schedules vary according to the device, indication, and treatment plan, so the clinician discusses the expected number and frequency of sessions before treatment begins.

Potential Advantages Of TMS Treatment

For appropriately selected patients, TMS provides a noninvasive treatment option that can be considered alongside other approaches.

TMS does not require surgical implantation because stimulation is delivered externally.
Treatment sessions allow the clinical team to monitor the person’s response and tolerability over time.
A treatment course can be planned around the person’s clinical needs and the specific TMS protocol being used.
TMS may be considered when a person has not achieved satisfactory improvement with previous depression treatment, depending on the applicable device and clinical criteria.

When TMS May Be Discussed

A person may ask a clinician about TMS when:

Depression symptoms remain significant despite previous treatment
Previous antidepressant treatment has not provided sufficient improvement
Medication side effects or treatment preferences prompt discussion of alternatives
A clinician believes a noninvasive brain-stimulation treatment may be appropriate
The person wants to understand how TMS compares with other treatment options

FAQs

What happens during a TMS treatment session?

The TMS device is positioned near the patient’s head and delivers controlled magnetic pulses to a targeted brain area. The person remains awake during the session, and the treatment team monitors tolerability and response.

How many TMS sessions does someone need?

A TMS course generally involves multiple treatment sessions rather than a single appointment. The number and schedule depend on the specific device, clinical indication, and treatment plan.

Is TMS painful?

People can experience sensations such as tapping or discomfort at the treatment site during stimulation, and individual experiences vary. The treatment team can discuss expected sensations and monitor how the person tolerates each session.

Who is a candidate for TMS?

Eligibility depends on the specific TMS device, FDA-cleared indication, medical history, diagnosis, and previous treatment experience. A clinician evaluates these factors before recommending treatment.

What happens after a TMS treatment course?

The clinician reviews the person’s response and discusses appropriate follow-up care. TMS may be used as part of a broader treatment plan, and ongoing mental health care may still be appropriate after the treatment course.
