Transcranial Magnetic Stimulation Therapy
Transcranial Magnetic Stimulation or TMS is a simple procedure that uses magnetic induction to stimulate brain cells. This non-invasive method can treat depression effectively as antidepressants or psychotherapy. Usually, doctors recommend TMS for people who haven’t responded well to or can’t tolerate antidepressants medication or psychotherapy.
How TMS Works
During TMS therapy, an electromagnetic coil is placed on the scalp near the front region of the head (the forehead). The electromagnetic pulses painlessly and stimulates the nerve cells in the brain concerned with mood control. When administered in rapid succession, it is referred to as rTMS or repetitive TMS.
Although studies about TMS haven’t yet fully explained the treatment’s effect in the brain, it lessens depression symptoms and improves the patient’s overall mood. It’s commonly prescribed to people who can’t tolerate standard depression treatments.
Not Everyone Can Benefit from TMS Therapy
The machine acts like an MRI and reacts to any magnetic sensitive objects. People with a permanent metal implant can’t receive TMS therapy. TMS can cause those metal objects to move, heat up, malfunction. People who have the following cannot undergo TMS:
- Aneurysm coils
- Bullet fragments located near the head
- Deep brain stimulators
- Electrodes used to monitor brain activity
- Facial tattoos that have metallic ink
- Metallic implants
- Other metal devices or objects implanted in the body ,particularly in or near the head
- Stents in the neck or brain
Preparing for TMS Therapy
TMS physicians usually check the following before recommending TMS therapy to patients. These include the following:
- Psychiatric evaluation to assess the extent of depression
- Physical exams like laboratory test
- Patients with any medications including over-the-counter drugs and other supplements
- People who may have co-existing mental disorder
- Patients with a family history of seizures or epilepsy
- Any brain damage suffered from injury or other illnesses
- Severe episodes of headaches
- other medical conditions like drug addiction
As a non-invasive technique, TMS can be done inside a doctor’s office. It doesn’t require any medical procedures like anesthesia or the like. However, it is best to get a family member to assist the patient during the first therapy session, as they might not know how TMS affects them. Usually, TMS sessions are carried out on a daily basis about five times a week for one and a half months.
The Initial Treatment
Treatment usually lasts for under an hour and the doctor will need to determine the best spot to place the magnets. This can assure the best possible dose of stimulation in the brain. Even though it’s an effective alternative therapy, TMS may not work under the following conditions:
- Psychological problems that show signs of detachment from reality
- Depression that has lasted for several years
- Any Electroconvulsive therapy (ECT) in the past that didn’t work as intended
Common Side Effects of TMS
Many experts consider using TMS as a safe form of alternative therapy. But, it can also trigger some health hazards like:
- Scalp soreness at the site of stimulation
- Spasms or twitching of facial muscles
Serious side effects rarely happen but include:
- Mania in people with bipolar disorder
- Hearing loss if ears aren’t properly protected
Further studies regarding TMS therapy are needed to determine any potential long-term side effects.
