A plain comparison for parents deciding what comes next after antidepressants have not worked well enough for their teenager.

Parents rarely ask this as an abstract comparison. They ask it because a medication has not worked, or has worked partially, or has come with side effects their teen cannot live with, and they want to know whether there is a different kind of option.
The short answer is that these are not competing treatments. TMS is cleared as an adjunct, which means it is added to existing care rather than swapped in for it. But understanding how they differ helps explain why one might work when the other has not.
Antidepressants work chemically and systemically. They are taken orally, absorbed, and circulate throughout the body, affecting neurotransmitter activity broadly. The effect is not confined to the brain, which is why side effects often show up elsewhere in the body.
TMS works magnetically and locally. A coil positioned against the head delivers magnetic pulses to specific brain regions involved in mood regulation. Nothing is ingested, nothing circulates, and the stimulation is targeted rather than systemic.
That difference in mechanism is the reason a patient who has not responded to several medications may still respond to TMS. It is not a stronger version of the same approach; it works differently.
Antidepressants commonly produce systemic effects. Depending on the medication these can include weight changes, sleep disruption, gastrointestinal effects, sexual side effects, and emotional blunting. For adolescents specifically, antidepressants carry an FDA boxed warning regarding increased risk of suicidal thoughts and behaviors in children, adolescents, and young adults, which requires close monitoring, particularly early in treatment.
TMS most commonly produces pain or discomfort at or near the treatment site. This occurs during the treatment course and for most patients does not continue past the first week. There is a rare risk of seizure associated with TMS therapy, occurring in fewer than 0.1 percent of patients.
For families who discontinued a medication because of how it made their teen feel day to day, the absence of systemic effects is usually the deciding factor in considering TMS.
Antidepressants require a daily dose and periodic follow-up appointments. They typically take several weeks to show effect, and finding the right medication and dose often involves multiple trials over months.
TMS requires in-office sessions across a course of treatment lasting several weeks. That is a larger scheduling commitment in the short term. The first visit, which includes motor threshold determination, runs about 60 to 90 minutes; subsequent sessions are shorter because the treatment coordinates are already recorded.
This is worth being honest about. TMS asks more of your calendar than a daily pill does. For most families the trade is worth considering only after medication has already been tried.
In a large registry study of patients treated with NeuroStar TMS, 83 percent of patients who completed the treatment course showed measurable improvement in depression symptoms, and 62 percent no longer met diagnostic criteria for major depressive disorder afterward (Sackeim et al., 2020, Journal of Affective Disorders).
That data comes from adult registry patients. Individual results vary, and neither treatment carries a guarantee.
NeuroStar Advanced Therapy is indicated as an adjunct for the treatment of major depressive disorder in adolescent patients ages 15 to 21.
The word adjunct is doing real work in that sentence. It means TMS is added to existing treatment. Your teen does not stop therapy, and any medication decision remains with their prescribing physician.
In practice, most adolescents who begin TMS at our practice have already tried at least one antidepressant. That history is part of the clinical picture Dr. Greenberger evaluates, and it is also what most insurers require documentation of before authorizing treatment.
This is not a decision to make from a web page, including this one.
Dr. Brett Greenberger, who is board certified in child and adolescent psychiatry as well as adult psychiatry, conducts a 60 minute evaluation covering your teen’s full psychiatric and treatment history. That evaluation determines whether TMS is clinically appropriate.
Before that, the free consultation with our Clinical Coordinator costs nothing and commits you to nothing.
No. It is cleared as an adjunct treatment, used alongside existing care. Medication decisions stay with the prescribing physician.
That is the typical arrangement, since TMS is an adjunct treatment. Dr. Greenberger will discuss your teen’s specific situation during evaluation.
Both take time. Antidepressants generally take several weeks to show effect, and finding the right one can take months of trials. TMS involves a treatment course over several weeks. Response timing varies by individual for both.
They work through different mechanisms. Medication works chemically and systemically; TMS works through targeted magnetic stimulation. Not responding to one does not predict the response to the other.
TMS is a covered benefit under most plans when clinical criteria are met, which typically includes documented lack of satisfactory improvement from antidepressants. Our staff handles prior authorization. See our insurance and coverage page.
