rTMS FAQs

What is rTMS?

Repetitive Transcranial Magnetic Stimulation (rTMS) is a non-invasive treatment for depression. It uses magnetic energy applied to the surface of the brain to stimulate nerve cells involved in mood regulation.

rTMS has been shown to be effective, particularly for people who have not responded to antidepressant medication.

How does rTMS work?

During treatment, you will sit comfortably while a small coil is placed against your scalp.

The machine delivers magnetic pulses that stimulate targeted areas of the brain associated with mood. These pulses create small electrical currents that help regulate brain activity.

How long does treatment take?

Each session typically takes 20 to 45 minutes.

A standard course of treatment usually involves:

• 5 sessions per week (Monday to Friday)
• Over approximately 4 weeks

Your treatment plan will be tailored to your individual needs.

What does rTMS feel like?

Most people describe the sensation as a light tapping on the scalp.

It may feel unusual or slightly uncomfortable at first, but most patients adjust quickly. Any discomfort typically only occurs during the session.

Do I need to take any precautions?

Yes. During your treatment:

• Let your treating team know about any changes to your health or medications
• Avoid illicit substances and excessive alcohol, as these may increase the risk of side effects

What are the common side effects?

rTMS is generally well tolerated. Some people may experience:

• Mild headache
• Scalp discomfort
• Neck tension

These effects are usually temporary and can be managed with simple pain relief such as paracetamol.

What are the risks?

rTMS is considered a safe treatment when delivered under clinical guidelines.

A rare but serious risk is seizure, which occurs in approximately 1 in 30,000 treatment sessions. This risk is comparable to, or lower than, many antidepressant medications.

Other possible risks include:

• Fainting (rare and not harmful)
• Temporary hearing changes (earplugs are provided)
• Mood changes, including a small risk of mania in people with bipolar disorder
• Heating of metal in or near the head

All patients are carefully assessed before starting treatment to ensure it is safe and appropriate.

When is rTMS not suitable?

rTMS may not be recommended if you:

• Have a history of seizures or epilepsy
• Have metal implants in or near the head (e.g. surgical clips, cochlear implants)
• Have implanted medical devices such as a pacemaker
• Have a serious or unstable medical condition
• Have a recent or active brain condition (e.g. stroke)
• Are pregnant or may be pregnant
• Are currently withdrawing from alcohol or substances
