Transcranial magnetic stimulation (TMS) is a non-invasive, FDA approved procedure that uses magnetic resonance to target specific parts of the brain.
Magnetic field pulses and electrical currents stimulate nerve cells in the prefrontal cortex, which has proven to effectively treat conditions such as drug addiction and depression.
TMS therapy is not an instantaneous treatment. It causes gradual changes in the brain over time and must be given on an on-going basis. It is usually applied for thirty minutes at a time, five days a week, for six to eight weeks. Due to the need for this prolonged exposure, this therapy is sometimes referred to as repetitive transcranial magnetic stimulation, or rTMS.
Repetitive TMS is typically used when other treatments have not been effective for patients.
There are very few side effects of TMS therapy, and very few patients discontinue treatment because of them. The most common side effects that do occur are typically mild and include:
TMS therapy is mainly used to treat major depressive disorders, but it is also used to treat other conditions, including:
TMS therapy is a generally safe and effective treatment for alcoholism (alcohol use disorder) and drug addiction (substance use disorder). The magnetic pulses have been shown to calm the areas of the brain that cause cravings. By targeting these areas, patients can break free from addiction without using pharmaceutical pills, which can have more adverse side effects than TMS therapy.
TMS therapy has shown promising results when treating anxiety. It is especially useful when other types of treatments, such as pharmaceuticals, have failed. TMS therapy does not completely suppress anxiety, but it reduces symptoms and can lead to significant improvements for patients.
Treatment of depression is the most common use of TMS therapy. It is particularly helpful for treatment-resistant depression that is not responding to antidepressant medications. TMS therapy usually takes a few weeks before patients feel any noticeable improvements. Depression symptoms gradually begin to fade with consistent treatment.
The benefits of TMS therapy include:
The downsides of TMS therapy include:
TMS therapy’s average cost is between $400 and $500 per session, with a total cost of around $15,000 for a full course of treatment.
This is considerably less than the most comparable treatment, electroconvulsive therapy (ECT), which costs about $2,500 per treatment session and requires a full ten sessions. You would also have to factor in the cost of a weeklong hospital stay for ECT treatment, which is not needed with TMS therapy.
Most TMS therapies have a success rate of 70 to 80 percent.
Generally, TMS therapy is a safe and effective treatment for alcoholism (alcohol use disorder) and drug addiction (substance use disorder). This therapy is also well-tolerated, non-invasive, non-addictive, and produces less severe side effects than other treatments.
Each individual's level of depression is unique, so it is difficult to determine how long TMS treatment will last. Some patients have mild to moderate depression, while others struggle with severe depression. However, most patients who let the treatment run its full course see improvements in their symptoms for six months to a year+.
There is no evidence that suggests TMS treatment can make anxiety or depression symptoms worse.
