What is TMS?
TMS stands for Transcranial Magnetic Stimulation and is a form of neuromodulation that uses magnetic fields to stimulate nerve cells in the brain. It is used to treat depression, anxiety, and other mental health conditions. It is also used to improve cognitive performance, reduce pain, and treat neurological disorders.
How it works
Mechanism of action:
By converting electrical energy into magnetic energy, TMS generates electrical current to the area below the positioned coil. Research has indicated the principal area of the brain controlling mood to be the left dorsolateral prefrontal cortex, where the coil is positioned directly over. The strength of stimulation varies between patients and is calculated on their individual motor threshold.
What does it feel like?
Felt on the scalp, the Left sided Depression protocol induces a tapping sensation that lasts for 4 seconds, followed by an 11 second gap. This is timing of one of our most popular treatment protocols. Treatment begins on a low setting. If the patient is comfortable, the TMS nurse will gradually increase the stimulation level. Some patients may find the treatment strange in the beginning but this sensation usually decreases within the first 2-4 sessions and can be alleviated with changes in coil position.
Who is it suitable for?
People who suffer from treatment resistant depression and have had unsuccessful attempts with antidepressant medication treatment, TMS may be a suitable option for these patients. As TMS doesn’t carry a risk of cognitive impairment or memory loss, this treatment is suitable for patients who are seeking an alternative to electric shock therapy. TMS may not be suitable if the patient has any metal implants in head/neck or a history of seizures.
