Transcranial Magnetic Stimulation, or TMS, is a non-invasive procedure that uses magnetic fields to stimulate nerve cells in the brain to improve symptoms of depression. Doctors typically use TMS when other depression treatments haven’t been effective. This treatment involves delivering repetitive magnetic pulses, so it’s sometimes called repetitive TMS or rTMS. While primarily used for major depressive disorder, TMS is also being explored for conditions like OCD and migraines. It offers an alternative pathway for individuals seeking relief from persistent mental health challenges.
How it Works Step by Step
Understanding the mechanics of transcranial magnetic stimulation can help address concerns about the procedure. Because TMS uses electromagnetic induction, each session precisely directs the magnetic field to targeted brain areas via controlled parameters. This verifies that the intervention produces the intended therapeutic effect, and it enables the process to remain consistent and predictable for each patient.
- Placement of the Coil: An electromagnetic coil is placed against your scalp near your forehead. The placement is precise and targets the specific area of the brain involved in mood regulation.
- Generation of Magnetic Pulses: The coil delivers brief magnetic pulses. These pulses easily pass through the skull and into the brain without causing pain.
- Stimulation of Neurons: The magnetic pulses induce small electric currents in the targeted brain region. This stimulates nerve cells that may be underactive in people with depression.
- Activation of Brain Regions: The stimulation activates brain regions that show decreased activity in depression. Over time, this repeated activation can lead to changes in brain activity levels.
- Normalization of Mood: By restoring normal activity patterns, TMS helps alleviate depressive symptoms and improve overall mood regulation.
What to Expect
During the session, you will sit in a reclining chair. You remain awake and alert throughout the entire procedure, and you may be given earplugs to wear. The technician will position the magnetic coil against your head. When the machine is turned on, you will hear clicking sounds and feel a tapping sensation on your forehead. The treatment typically lasts about 20 to 40 minutes. You can return to your normal daily activities immediately after the session is over. There is no need for anesthesia or recovery time, so you can drive yourself to and from the appointment. A typical course of treatment involves sessions five times a week for four to six weeks.
Why Transcranial Magnetic Stimulation is Beneficial
TMS offers several advantages for individuals struggling with depression, and it provides a different approach compared to traditional medication or therapy. The sessions do not require sedation. Because TMS targets specific areas of the brain without affecting the rest of the body, individuals may experience fewer systemic side effects compared to some pharmaceutical treatments.
- Non-Invasive Nature: TMS does not require surgery or electrode implantation. It is performed entirely from outside the body.
- Few Side Effects: Unlike many antidepressant medications, TMS does not typically cause systemic side effects like weight gain or sedation. The most common side effect is mild scalp discomfort or a headache during treatment.
- No Anesthesia: Since anesthesia is not used, there is no risk of sedation-related complications. You remain fully conscious and functional.
- Effective for Resistant Depression: It is a viable option for those who have not found relief through standard medications.
Ask a Doctor Today
If you struggle with depression and medication hasn’t helped, TMS might be a suitable option for you. Discuss your full medical history with a healthcare provider. They can determine if you are a good candidate for this therapy. Transcranial Magnetic Stimulation is a safe procedure, but it is not right for everyone, specifically those with non-removable metal in their heads. Reach out to a specialist to learn more about how this technology works and if it aligns with your treatment goals. Your doctor can provide the guidance you need to make an informed decision about your mental health care.
