When talk therapy and antidepressants don’t shift depression, people often assume they have “failed” treatment. More often, the treatment is simply not matching the biology and the pattern of symptoms. That’s where TMS therapy for depression can sit in the mix: a clinic-based, non-invasive medical treatment that uses magnetic pulses to influence brain circuits linked with mood. It won’t suit everyone, and it doesn’t cancel the need for support, but it can be worth discussing when symptoms stay stubborn.
When therapy hits a wall
Depression isn’t one neat condition. Two people can meet the same diagnostic criteria and still have different drivers and different responses to care.
Some improve with psychotherapy once sleep, alcohol use, grief, or a punishing workload is addressed. Others keep feeling flat, slowed, and detached despite earnest work in therapy and multiple medication trials.
At that point, the gap between insight and capacity becomes obvious. People may understand their triggers and still struggle to get moving in the morning, concentrate at work, or feel much at all.
A psychiatrist may then suggest a physical treatment aimed at the brain networks involved in mood regulation, alongside ongoing psychological care.
What is TMS therapy and what happens during it?
- Repetitive transcranial magnetic stimulation (rTMS) uses an electromagnetic coil placed against the scalp.
- The coil produces brief magnetic pulses that induce small electrical currents in targeted brain regions. NICE describes the procedure as applying the coil to stimulate parts of the brain using magnetic fields.
- Treatment is delivered while you’re awake and doesn’t require anaesthesia. Most people return to normal activities straight after a session.
- An initial course includes prescription and “mapping”, followed by supervised delivery of treatment sessions for eligible patients with major depressive disorder. In other words, it’s a course, not a single appointment.
- Clinics monitor symptoms across the weeks, so decisions are based on trend rather than judged after a few visits.
What benefits are realistic to expect?
- Researchers usually report outcomes as response (meaningful symptom improvement) and remission (symptoms reducing to a low level).
- A 2023 meta-analysis of sham-controlled trials reported remission around 36% with active rTMS versus about 8% with sham stimulation.
- Numbers differ across studies, but the pattern is consistent: active treatment outperforms placebo conditions.
- In day-to-day life, the first changes can be practical rather than dramatic. People might find it easier to start tasks, tolerate stress, or stay present in conversations. Sleep and concentration can shift before mood catches up.
For some, TMS makes psychotherapy easier to use because attention and motivation improve. For others, it provides an option when medication side effects have been a deal-breaker.
Safety, side effects, and Australian access
rTMS is generally well tolerated. Headache and scalp discomfort are common, with serious adverse events uncommon when appropriate screening is done.
It’s sensible to ask upfront about TMS side effects, including what’s common, what’s rare, and what the clinic does if discomfort flares.
Clinics also screen for seizure risk and for implanted devices or metal near the head (dental work is usually fine, but it still needs mentioning).
In Australia, Medicare introduced rTMS items from 1 November 2021, with requirements around referral, eligibility, and psychiatrist oversight. If you’re in Sydney and considering TMS therapy, bring a clear medication history and therapy background to your assessment.
Ask how progress is measured and what the plan is if symptoms return after a course.

Frequently Asked Questions
1. What is treatment-resistant depression, and when should I consider TMS?
Treatment-resistant depression usually means you’ve had adequate trials of standard treatments and remain significantly unwell. Eligibility is tied to diagnosed major depressive disorder and prior antidepressant trials at therapeutic doses and duration, under psychiatrist oversight. TMS is often considered when therapy and medication haven’t brought enough relief, or when medication side effects limit options. Your clinician will also check safety factors like seizures or implants.
2. How effective is TMS for treatment-resistant depression?
Effectiveness is reported as response and remission. Controlled trials and meta-analyses show remission is more likely with active rTMS than with sham stimulation. Your own chances depend on factors like symptom severity, co-occurring anxiety, and completing the full course as planned.
3. How long does it take for TMS to work for depression?
Some people notice changes in energy, sleep, or reactivity within the first couple of weeks; others need longer. Medicare allows an initial course with supervised delivery across multiple sessions, reflecting that progress is assessed over time. Clinics usually track symptoms weekly to guide decisions.
4. What are the most common side effects of TMS?
Headache, scalp tenderness, and discomfort during stimulation are common early on, and many people find these settle as treatment continues. Mention any seizure history or implanted devices so the clinic can assess safety properly.
5. Does Medicare cover TMS for depression in Australia?
Medicare rebates are available for certain rTMS services for major depressive disorder when eligibility criteria are met and a trained psychiatrist prescribes and supervises care. Out-of-pocket costs vary by clinic and individual circumstances. Ask the clinic for the item numbers and a written quote before starting.
