Repetitive Transcranial Magnetic Stimulation (rTMS) is a non-invasive medical procedure that uses magnetic fields to stimulate nerve cells in the brain. These magnetic fields induce tiny electric currents, prompting nerve cells to release neurotransmitters like dopamine and serotonin. This process can help treat conditions such as Depression, Migraine, Obsessive-Compulsive Disorder (OCD), and aid in smoking cessation. However, rTMS is contraindicated in individuals with certain conditions, including pregnancy, significant head injury, or those with implanted devices.
How is it administered?
rTMS is administered by placing an insulated magnetic coil on the patient’s head, typically on the left side or top. The device is adjusted until the patient’s motor threshold is determined—the minimum energy required to produce a hand twitch. Once established, the coil is moved to the front of the head to target specific brain regions related to the patient’s condition. The treatment involves delivering pulses with rest periods in between, and sessions usually last 30 to 40 minutes.
How safe is it?
rTMS has been approved by scientific bodies, including the FDA in the United States, for the treatment of Major Depressive Disorder, OCD, migraine, smoking cessation, anxiety co-morbid with MDD, and brain mapping. However, it is not suitable for everyone, particularly those with metal implants, significant neurological disorders, or certain medical conditions.
What are the side effects?
Generally considered safe, rTMS can cause mild to moderate side effects, such as headaches, scalp discomfort, and tingling sensations, which typically diminish over time. Serious side effects are very rare. For full info, please check the brochure.
