Transcranial Magnetic Stimulation, or TMS, is a non-invasive treatment for depression that uses magnetic pulses to stimulate parts of the brain involved in mood regulation. In Australia, it is generally considered for adults with major depressive disorder when standard treatment, including antidepressant medication, has not provided enough relief. Treatment is delivered while the patient is awake, and it does not require surgery or anaesthesia.
What is TMS therapy?
TMS uses an electromagnetic coil placed against the scalp. When the machine is activated, it produces brief magnetic pulses that pass through the skull and trigger small electrical currents in the outer layer of the brain. In depression care, the target is often the prefrontal cortex, an area linked with mood, motivation and decision-making.
The term rTMS treatment refers to repetitive transcranial magnetic stimulation, which means the pulses are delivered in repeated sequences across a planned course of sessions rather than as a one-off intervention.
How TMS works for depression
Depression is not simply a matter of low mood. It is associated with changes in brain networks that influence emotion, thinking and energy levels. TMS is used to act on those networks in a focused way.
Repeated stimulation may help alter activity in brain circuits that are underactive or functioning poorly, which can lead to symptom improvement over time for some people.
In practical terms, treatment usually follows a clear sequence:
- A psychiatrist assesses whether TMS is clinically appropriate
- The treatment area is mapped and settings are tailored to the patient
- The coil is positioned against the scalp at each visit
- Magnetic pulses are delivered for a set period
- Sessions are repeated across several weeks so the effect can build gradually
That gradual pattern matters. TMS is not designed as an instant fix. A person may notice little change in the first week or two, then begin to feel a shift as the course continues. For general readers, that is often the most useful point to understand: TMS is structured, cumulative treatment rather than a single dramatic event.

What to expect during treatment
A TMS appointment in Sydney usually takes place in an outpatient setting. The patient sits in a treatment chair, remains fully awake and can return to ordinary activities afterwards. During the session, the machine produces a clicking sound, and the pulses may feel like tapping on the scalp. Some people find this unusual at first, though tolerance often improves as treatment continues.
The setting should not distract from the essentials. What matters most in TMS therapy is careful assessment, medical oversight and a clinic that explains the treatment course clearly.
Good services do more than operate a machine; they assess suitability, monitor response and review progress over the full course of care.
TMS vs Antidepressants
| Factor | TMS | Antidepressants |
|---|---|---|
| How it works | Uses magnetic pulses to stimulate targeted brain areas involved in mood regulation. | Uses medication to alter brain chemistry linked to depression symptoms. This effect is systemic rather than locally targeted. |
| How it is given | Delivered in a clinic as scheduled outpatient sessions while the patient remains awake. | Taken at home, usually as daily tablets or capsules prescribed by a doctor. |
| Usual place in treatment | In Australia, Medicare-subsidised rTMS is generally for adults who have tried at least two classes of antidepressants without enough benefit. | Often used earlier in treatment and commonly prescribed in general practice and psychiatry. |
| Invasiveness | Non-invasive and does not require surgery or anaesthesia. | Non-surgical as well, but involves a medicine acting throughout the body rather than direct external stimulation of the brain. |
| Time commitment | Requires repeated clinic visits over several weeks; Medicare item information allows an initial course of up to 30 sessions for eligible patients. | Usually easier to fit around daily life because it is taken at home, though regular medical review is still needed. |
| Common side effects | Often includes scalp discomfort, headache, light-headedness, or brief facial twitching during treatment; seizure is a rare but recognised risk. | Side effects vary by drug and person, but may include issues such as nausea, sleep disturbance, sexual side effects, or weight change. |
| Suitability | Best assessed by a psychiatrist, especially for treatment-resistant depression or where medicine side effects have been difficult. | Suitable treatment depends on diagnosis, symptom profile, medical history and tolerability, and is decided by the treating clinician. |
| Can they be used together? | Yes, TMS may be used alongside medication in some cases, depending on the treatment plan. This is a clinical decision. | Yes, antidepressants may continue during TMS where clinically appropriate. |
Who may consider TMS in Sydney?
- Adults with major depressive disorder
- People who have not improved enough with standard treatments such as antidepressants
- People who cannot tolerate medication side effects
- Those looking for a non-invasive treatment option
- People able to attend regular sessions over several weeks
- Individuals who have completed safety screening and psychiatric assessment
- People assessed by a qualified psychiatrist as suitable for TMS
How to choose a Sydney TMS clinic
While looking for a TMS clinic, the sensible choice comes down to a few practical questions:
- Who performs the psychiatric assessment before treatment starts?
- Is Medicare eligibility checked in advance?
- How is progress reviewed during the course?
- What support is offered if symptoms return later?
- Are side effects and limitations explained plainly, without overselling the treatment?
That final point is worth keeping in mind. Health information is more useful when it is measured and clear. TMS can be a valuable option, but it still needs to be matched to the right patient and the right clinical setting.
Frequently Asked Questions:
1. Is TMS therapy covered by Medicare in Australia?
Yes, Medicare rebates are available for eligible patients in Australia. TMS was added to the Medicare Benefits Schedule from 1 November 2021 under specific item numbers for prescription, mapping, treatment and retreatment. Eligibility rules apply, so not every person with depression will qualify.
2. How many sessions of TMS are needed for depression?
The exact number varies, though an initial Medicare-subsidised course can include up to 30 sessions, with later retreatment of up to 15 sessions for eligible patients. A psychiatrist decides the plan based on response, safety and clinical need.
3. What are the side effects of Transcranial Magnetic Stimulation?
Common side effects are usually mild to moderate and can include scalp discomfort, headache, light-headedness and brief facial muscle twitching. Serious adverse effects are uncommon, but seizure is recognised as a rare risk, which is why screening and supervision matter.
4. How long do the results of TMS treatment last?
There is no fixed answer. Some people maintain improvement for months, while others may need further treatment later. Long-term outcome depends on the severity of illness, prior treatment history and ongoing clinical care.
The Next Step
The best next step is a careful clinical assessment that looks at diagnosis, past treatment and whether TMS is an appropriate fit for the individual.
If you are exploring treatment options for depression, speaking with a qualified clinician can help clarify whether TMS is an appropriate choice for your circumstances.
