Repetitive Transcranial Magnetic Stimulation (rTMS) is a non-invasive therapeutic technique that uses electromagnetic fields to stimulate specific regions of the brain. It involves the application of repetitive magnetic pulses to the scalp, which induce electrical currents in the brain, leading to changes in neuronal activity. This technique has gained recognition for its potential in treating various neuropsychiatric disorders.
In rTMS, an electromagnetic coil is positioned over the scalp, targeting specific areas of the brain. The magnetic pulses pass through the scalp and skull, painlessly reaching the desired brain regions. The treatment is typically delivered in daily sessions over several weeks, with each session lasting around 20 to 30 minutes. The frequency and intensity of the magnetic pulses are carefully tailored to the individual's needs and the condition being treated.
The main application of rTMS is in the treatment of major depressive disorder when other treatment methods, such as medications or therapy, have not been successful. It has also shown promise in managing other psychiatric conditions, including anxiety disorders, obsessive-compulsive disorder, and post-traumatic stress disorder, as well as in reducing symptoms associated with chronic pain and certain movement disorders.
RTMS is generally considered a safe procedure, with minimal side effects such as scalp discomfort or headaches being the most commonly reported. However, it is essential to undergo this treatment under the supervision of a qualified healthcare professional who will assess the patient's suitability, determine the optimal treatment parameters, and monitor the progress and any potential adverse effects throughout the course of therapy.
