Repetitive transcranial magnetic stimulation (rTMS) is a novel treatment for neuropsychiatric illness. A non-invasive intervention, rTMS utilizes the application of a repetitively pulsed magnetic field over the scalp to induce an electric field within a discrete area of the cerebral cortex. This electric field results in altered ion flow across the neuronal cellular membrane and ultimately changes in neuronal polarization. The end result is altered neuronal activity in the area of the cerebral cortex where the rTMS is applied.12 rTMS is a safe and well-tolerated intervention that received FDA approval for treatment refractory major depressive disorder in 2008 and has since become commonly used in clinical practice.13
