Revolutionizing Treatment with Brain Stimulation: The Power of rTMS (Repetitive Transcranial Magnetic Stimulation) in Treating Mental Health Conditions
by David Kua
Some people experience difficulties with the effectiveness of their medication and are trying out brain stimulation therapy as an alternative method of treatment to alleviate their symptoms. It is often considered when medications do not provide the desired relief and can offer hope for those who have struggled to find effective treatment options.
Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive therapeutic technique that uses magnetic pulses to target particular parts of the brain. This technique is widely used to treat a variety of mental health issues, including depression, anxiety, OCD, and neurological conditions such as Parkinson’s Disease. During a rTMS session, a coil is put on the head and magnetic pulses are delivered to the targeted area of the brain, which aids in the regulation of neuron activity (National Institute of Mental Health, n.d.).
In 2008, the FDA approved the use of rTMS as a treatment option for individuals with mildly treatment-resistant depression, where traditional antidepressants have not been effective in providing relief from symptoms.
How does rTMS work?
These magnetic pulses can help rewire the brain circuits that are responsible for conditions like depression. These changes in brain activity are believed to be how the treatment works.
What happens during the procedure?
During the procedure, the person is awake and many are able to return to their regular routine following the procedure. No medication or anesthesia is needed. Each therapy session typically takes about 30 minutes to complete. The person will be sitting in a comfortable chair during the session. Usually, the therapy consists of a 30-minute session every day for a period of four to six weeks. Several people report experiencing a minor tapping sensation on their scalp during the session.
Who can benefit from rTMS?
Repetitive transcranial magnetic stimulation (rTMS) is a commonly used treatment for depression when antidepressants are not achieving the desired effect or for those who cannot cope with the side effects of antidepressants. Overall, the side effects of TMS are minor and short in duration compared to antidepressants.
However, due to the strong magnetic field produced during rTMS , it's not recommended for some people who have metal implants - eg. coils and stents.
Over time, rTMS can improve mood, reduce symptoms of mental illness, and improve overall cognitive function. While not a cure-all, rTMS has shown promising results in helping people manage their mental health.
Future directions
Current clinical studies dig deeper into the ability to customize stimulation locations according to each person's unique brain activity. Most recently, researchers have been focusing on expanding the use of repetitive TMS pulses (rTMS) to treat other mental health and neurological conditions.
Remember that even on those dark days, there may be an option of light around the corner. It might be beneficial to discuss this with your doctor as a potential solution for improving your mental well-being. Additionally, make sure to take proactive steps by engaging in physical activity, staying connected with others, and keeping your mind intellectually stimulated.
