With rTMS treatment, short pulses of magnetic energy are delivered to the specific area of the brain that's believed to be responsible for mood control. These rapid pulses go through the skull to stimulate and alter the electrical events occurring in the brain, making this treatment ideal for patients with major depressive disorder (MDD). Targeting the area right underneath the treatment coil, this noninvasive therapy encourages the neurons in the brain to begin firing and stimulates the surrounding cells. Using transcranial magnetic stimulation allows your doctor to increase the activity in the parts of your brain that have experienced a slowdown due to MDD.
