Repetitive transcranial magnetic stimulation (rTMS), which uses more intense electric pulses, is used to treat patients with unipolar depression. In rTMS, short electromagnetic pulses are delivered through the left side of the patient’s scalp in a specific pattern. The repeated magnetic pulses create electric currents, which stimulate nerve cells in the targeted spots in the brain. There are a few side effects that are associated with this treatment like headache and nausea but there are no long-term impacts that have been noted.
