What is Transcranial Magnetic Stimulation?
Transcranial magnetic stimulation is an advanced, non-invasive treatment for depression that involves stimulation of the nerve cells in your brain by the use of magnetic fields. This technique is generally used in cases when the patient fails to respond to other treatment methods for depression.
Indication of Transcranial Magnetic Stimulation
TMS therapy is indicated for the treatment of major depressive disorder in adult patients who have:
- Failed to receive satisfactory improvement from prior antidepressant medication
- Experienced side effects from taking medications for the treatment of depression
- Symptoms of depression that interfere with activities of daily living
Contraindications for Transcranial Magnetic Stimulation
TMS therapy is contraindicated in patients with:
- Non-removable metal implants inside or near the head
- Cochlear implants
- Vagus nerve stimulators
- Deep brain stimulators
Preparation for Transcranial Magnetic Stimulation
In preparation for the procedure, you may have to undergo a physical examination and psychiatric evaluation. You must also inform your doctor about any health conditions, allergies, and regular medications.
Procedure of Transcranial Magnetic Stimulation
- You will be asked to sit comfortably in a chair and an electromagnetic coil will be placed against your scalp near your forehead.
- This electromagnet coil produces a magnetic pulse that is used to stimulate the region of your brain responsible for mood control.
- According to studies, this pulse can activate the regions of the brain which usually have decreased activity due to depression.
- You’ll hear clicking sounds and feel a knocking, tapping, or tingling sensation on your head.
- The procedure lasts for about 40 minutes and you will be awake the entire time.
Postoperative Care after Transcranial Magnetic Stimulation
You will be allowed to leave soon after the treatment is completed, and you can resume your normal activities almost immediately as the treatment does not have any effect on your alertness or cognition.
Risk and Side effects of Transcranial Magnetic Stimulation
TMS is safe and generally risk-free. However, some people may experience:
- Headache
- Scalp discomfort at the site of stimulation
- Tingling, spasms, or twitching of facial muscles
- Lightheadedness
Benefits of Transcranial Magnetic Stimulation
Some of the benefits of Transcranial Magnetic Stimulation:
- Non-Drug Therapy: Transcranial Magnetic Stimulation is less likely to cause systemic side effects associated with some major depressive disorder medications.
- Comfortable Patient Experience: Patients do not have to use a mouthguard or wear a helmet and can return to routine activities immediately after the procedure.
