What is TMS?
Transcranial Magnetic Stimulation (TMS) is a non-invasive technique that utilises magnetic pulses to stimulate targeted brain regions.
It is most commonly used in the treatment of major depressive disorder—particularly in patients unresponsive to medication—but is also applied in managing anxiety disorders (PTSD, OCD), chronic pain and ADHD.
How does it work?
TMS uses magnetic pulses to stimulate parts of the brain that aren’t functioning at their usual level. Over time, this repeated stimulation encourages the brain to rewire itself by strengthening the connections between nearby neurons—a process called neuroplasticity.
For mood disorders, the coil is typically placed over the left dorsolateral prefrontal cortex—a region involved in the regulation of emotions. The stimulation intensity is determined by each patient’s motor threshold to ensure appropriate dosage.
During treatment, patients experience a tapping sensation at the stimulation site. While some patients find the sensation unusual at first, this often subsides after a few sessions. Adjustments to coil position can further enhance comfort.
TMS is an appropriate intervention for individuals with Treatment-Resistant Depression, especially when standard pharmacological treatments have been ineffective. It is generally safe, but contraindications include metallic implants in the head or neck and a personal history of seizures.

TMS Psychiatrist
Dr Cathrin Kusuma is an experienced psychiatrist who is passionate about providing empathic, evidence based, personalised care. She has trained in general adult psychiatry and has a special interest in perinatal psychiatry.
Cathrin is excited to provide TMS for patients with treatment resistant depression or those who prefer a non medication treatment option that is effective, drug free and with very minimal side effects.
Our Process
Initial Assessment (No Out-of-Pocket Cost)
Before starting treatment, you’ll attend an initial consultation to evaluate if TMS is the right option for you. Based on your psychological history and symptoms, we will develop a treatment approach specific to your needs and recovery goals.
Our Process
Mapping Appointment
In this one off mapping, your TMS Psychiatrist will identify the correct brain area to treat and measure your motor threshold. For Depression, this is typically the left dorsolateral prefrontal cortex. A small hand or finger movement helps us determine the exact dose required to activate the target brain region safely and effectively.
Our Process
TMS Treatment Sessions
You’ll relax in a reclining chair while the magnetic coil delivers pulses to the selected treatment site. Sessions take about 20 minutes and occur 5 times per week for 7 to 8 weeks. Many patients chat with nurses, enjoy music, or watch shows during the session.
Our Process
Mid and Final TMS reviews
We conduct mid-point and final reviews to ensure your treatment remains on track. Along with daily observations by our trained TMS nurses, these formal reviews allow us to monitor your progress and share updates with your GP or Psychiatrist.
