What is transcranial magnetic stimulation (TMS)?
Transcranial magnetic stimulation, or TMS, is a treatment for people with severe depression whose illness has not been helped by at least one antidepressant medication. It is a type of brain stimulation therapy. TMS elicits magnetic energy, which turns into electrical current underneath the patient’s skull, to help regulate the patient’s emotions. TMS works along with medication and is non-invasive (No surgery or radiation) What is depression? Depression is a common and serious medical illness. One aspect of depression is a lack of activity in the prefrontal cortex of the brain, or the area right above the eyes, that helps control emotions. It affects how the patient feels, thinks and acts.
What other conditions can TMS be used to treat?
TMS has shown great promise treating the depressed patient, but is also being studied for possible treatment of other conditions, such as depression after a stroke, Obsessive Compulsive Disorder (OCD) and Smoking Cessation.. Also, researchers are looking at TMS as a possible treatment for several other conditions including Autism.
What can you expect during the TMS procedure?
The procedure is usually performed by a trained technician under supervision of our Psychiatrist while the patient is awake and seated in a chair. A device with an electromagnetic coil is placed near the patient’s left prefrontal cortex, or the front side of the scalp, an area where a lack of functional and metabolic activity is found in the depressed patient.
A steady electric current is passed through this part of the brain causing neurons, or nerve cells, in the brain to send electrical impulses. These impulses will then trigger a chemical reaction that, over time, will help lift the patient’s mood.
Doctors typically recommend 36 sessions of TMS therapy, usually given 2-3 times per week for 6 weeks.
Risks / Benefits What are possible side effects of TMS treatment
Doctors report minimal side effects with TMS. Some may feel a twitching or vibrating sensation around the face, cheek or scalp, or complain of a headache or muscle soreness. There is a low risk of seizure.
Who would benefit from TMS?
Each patient is different and what works for one may not work for another.
TMS is used on the patient who has not responded to medication when treated for depression. There are studies indicating promising results from this treatment.
Who should not be considered for TMS?
The TMS procedure is not recommended for patients who have a history of seizures. Those who have a metal plate in their head, or any other metal in and around their head should not have the procedure done. Braces and fillings will not interfere with the treatment.
How long after the (TMS) treatment can the patient expect to see results?
Studies show that the patient often experiences relief from TMS within two to four weeks.
What follow-up is necessary after the TMS procedure?
- Depending on the patient’s outcome, follow-up sessions may be recommended every few weeks or months to help maintain the positive results.
How does transcranial TMS differ from electroconvulsive therapy (ECT)?
Both TMS and electroconvulsive therapy (ECT) are used to treat severe depression.
ECT has been used in the United States for more than 70 years and creates a more generalized brain stimulation. It sends a small electrical current that is sent through the brain to trigger a short seizure. The current causes a short seizure within the brain, which produces changes in the brain’s functioning and chemistry. The patient needs anesthesia during the procedure. ECT is usually recommended several times per week over three to four weeks.
The patient may experience confusion and some memory loss after the ECT procedure. Because anesthesia is used, additional risks must be considered, and means longer preparation and recovery time for each session.
The doctor may recommend ECT if a patient has tried multiple medications or therapies that have not worked, or if he or she is suicidal, psychotic or catatonic.In contrast, TMS is a more recent form of treatment. It is a much more targeted procedure. The patient is awake and alert the entire time. Side effects of TMS are minimal and the patient does not suffer any memory loss.
