Repetitive Transcranial Magnetic Stimulation (rTMS)
Queensland Specialist Centre offers rTMS for treatment-refractory depression, delivered by specialist TMS technicians under direct psychiatric supervision.
This video is for general information only. Individual treatment experiences may vary.
Repetitive Transcranial Magnetic Stimulation is a non-invasive, evidence-based treatment that uses focused magnetic pulses to stimulate specific regions of the brain involved in mood regulation. It is delivered as an outpatient treatment, requiring no anaesthesia, and patients can drive and return to normal activities immediately after each session.
A standard course consists of daily sessions (Monday to Friday) over four to six weeks, each lasting approximately 20–40 minutes. The treatment targets the dorsolateral prefrontal cortex (DLPFC) and is associated with antidepressant effects in patients who have not responded adequately to medication. Response rates vary between individuals and cannot be guaranteed.
Features of Treatment
- ✓Non-invasive — no surgery or anaesthesia required
- ✓Outpatient procedure — no hospital admission required
- ✓Generally well tolerated, with no requirement for anaesthesia or recovery time
- ✓Bulk billed for eligible patients — no out-of-pocket cost for treatment sessions
- ✓May be combined with antidepressant medication
- ✓Evidence-based treatment listed on the MBS for treatment-refractory depression
- ✓A valid psychiatrist referral is required for MBS bulk billing
Risks & Limitations
- !Common side effects include scalp discomfort and headache, which are usually mild and transient
- !A small risk of seizure exists; a thorough safety screen is conducted before treatment
- !Not all patients respond — response rates vary and cannot be guaranteed
- !rTMS is not suitable for patients with certain metallic implants near the head
- !Maintenance treatment may be required in some cases
Treatment-Refractory Depression
Major Depressive Disorder (MDD) that has not responded to at least two adequate antidepressant trials. This is the MBS-approved indication for bulk billing.
MDD with Anxious Distress
Depression presenting with prominent anxiety, worry, or somatic symptoms, particularly where anxiolytic medications have been inadequate or poorly tolerated.
Depression with PTSD or OCD
Treatment-refractory depression occurring in the context of PTSD or OCD, where standard pharmacotherapy has proven insufficient.
Medication Intolerance
Patients unable to tolerate adequate antidepressant trials due to side effects, medical comorbidities, or drug interactions.
Bipolar Depression
Depressive episodes in Bipolar Disorder where antidepressants carry a risk of mood destabilisation, under appropriate mood-stabilising cover.
Antenatal & Postnatal Depression
Treatment-refractory depression during pregnancy or the postnatal period, where pharmacological options are limited by concerns regarding fetal or infant exposure.

Everybody here has been so wonderful, friendly and professional. The staff here have treated me with dignity, kindness, respect and understanding, which is so refreshing considering the state of a lot of healthcare services at the moment. Dr. Bandara, Dr. Ragu and the TMS team have gone above and beyond and I cannot thank them enough. You have all contributed to a large portion of my mental health journey that has gone largely ignored and unnoticed up until I began therapy here. My life has been substantially changed forever in the most positive of ways. Thank you all so much.
