What is TMS?
Understanding Transcranial Magnetic Stimulation
If you’ve been living with depression or another mental health condition that hasn’t improved with medication or therapy alone, you may have heard about Transcranial Magnetic Stimulation (TMS).
TMS is a non-invasive treatment that uses magnetic pulses to stimulate specific areas of the brain involved in mood regulation. TMS may be considered for some people with major depressive disorder whose symptoms have not adequately improved with previous treatments, following an assessment.
How does TMS work?
TMS uses a specialised device that delivers targeted magnetic pulses to the prefrontal cortex—the part of the brain associated with mood, emotions and decision-making.
In people experiencing depression, activity in this area of the brain can be reduced. The magnetic pulses are used to stimulate targeted nerve cells associated with mood regulation.
As TMS does not circulate through the bloodstream, its side-effect profile differs from that of antidepressant medicines. Potential side effects and individual suitability should be discussed with the treating clinician.
What conditions may TMS help treat?
TMS is commonly used in the treatment of major depressive disorder in appropriately assessed patients. Its use for other conditions depends on the individual clinical circumstances, the device’s approved intended purpose and assessment.
Depending on individual circumstances and specialist assessment, TMS may also be considered for other conditions, including:
Anxiety disorders
Obsessive-compulsive disorder (OCD)
Chronic pain
Post-traumatic stress disorder (PTSD)
Smoking cessation (in some settings)
Your doctor will determine whether TMS may be an appropriate treatment option for your individual needs.
What happens during treatment?
TMS is performed in a clinic while you remain awake and alert.
During each session:
- You sit comfortably in a treatment chair.
- A magnetic coil is positioned against your scalp.
- The device delivers short magnetic pulses to the targeted area of the brain.
- You may hear a clicking sound and feel a tapping sensation on your scalp during treatment.
Each session typically takes between 20 and 40 minutes, depending on the treatment protocol being used.
Some people may be able to resume usual activities following treatment. The treating clinician will provide advice based on the individual’s circumstances and response to treatment.
Frequently asked questions
Does TMS hurt?
Most patients describe TMS as causing a tapping or knocking sensation against the scalp.
Possible side effects may include scalp discomfort and headache. The treating clinician will discuss possible risks, side effects and what to do if symptoms occur.
How many treatments will I need?
TMS is delivered as a course of treatment rather than a single session. Treatment schedules vary according to the prescribed protocol and individual clinical circumstances. Some courses may involve several sessions per week over a number of weeks.
Some patients may also benefit from maintenance treatments following their initial course, depending on their response and their doctor’s recommendation.
What are the risks and side effects of TMS?
TMS is a non-invasive treatment that is generally well tolerated when delivered by appropriately trained clinicians. As with any medical treatment, it may involve risks and side effects, and individual experiences can vary.
TMS does not usually require anaesthesia or sedation, so patients remain awake during treatment. Some people may be able to return to their usual activities following an appointment, depending on their individual circumstances and response to treatment.
Possible side effects can include scalp discomfort and headache. Less common risks may also apply. Before treatment begins, the treating clinician will review the patient’s medical history, assess whether TMS is suitable and discuss the potential benefits, risks, side effects and alternative treatment options.
Who may be suitable for TMS?
TMS may be an option if you:
- Have depression that has not improved with medication or psychological therapy.
- Have experienced unwanted side effects from antidepressant medication.
- Are looking for a non-invasive treatment option.
The best way to determine whether TMS is right for you is through a comprehensive assessment with your mental health care team.
