Transcranial Magnetic Stimulation (TMS) Service for Depression

What is TMS?

Transcranial magnetic stimulation (TMS) is a non-invasive treatment where magnetic pulses are delivered via a coil to stimulate nerve cells in parts of the brain, to treat conditions including depression in adults.

Stimulating the parts of the brain that are underactive in depression has been well-proven to produce an antidepressant effect that is superior to medications, in those who have not responded well to antidepressants.

TMS does not require anaesthesia or surgery. It is not to be confused with electroconvulsive therapy (ECT). It does not affect cognitive function such as memory.

Who should consider TMS?

Those who have not responded well to antidepressants, psychotherapy, or are unable to tolerate medication may want to consider TMS. Speak to your psychiatrist to determine your suitability for TMS.

Who conducts TMS?

TMS is performed by licensed psychiatrists and trained staff supervised by the physician.

Is TMS suitable for everyone?

TMS is not recommended for those with any non-removable magneticsensitive metal in their head or neck, or those with a history of seizures. Please inform your doctor if this applies to you, when considering TMS. You will also be screened to ensure your safety for TMS.

What happens during TMS?

The patient is seated in a reclinable treatment chair and wears a cotton cap marked with the exact treatment spot. The TMS coil is placed on the patient’s head as marked on the cap, and the treatment begins. When the magnetic pulses are delivered, there is a clicking sound and the patient feels a tapping sensation on the scalp. Ear plugs are worn during the procedure and the patient is awake throughout.

How long is a course of TMS?

Each session of TMS lasts between 3 to 19 minutes depending on the protocol prescribed. The recommended number of TMS sessions is usually about 30 sessions, conducted daily over about 4 to 6 weeks, excluding weekends and public holidays.

Are there any side effects?

TMS is well-tolerated by most patients, who should be able to resume their daily activities including work or school right after each session. Some mild side effects may include a tapping sensation over the stimulation site or facial twitching only when the magnetic coil is turned on. Our staff can adjust the stimulation settings in such cases to make the procedure more comfortable.

A minority of patients may experience mild headaches which typically go away within a few hours after treatment and respond well to over-the-counter painkillers like paracetamol.
