NeuroStar is a non-invasive FDA-cleared therapy that uses short magnetic pulses to stimulate nerve cells in the area of the brain that controls mood. These pulses can have a lasting effect on the brain’s neurotransmitter levels, helping people suffering from depression achieve a positive response and, in some cases, long-term remission from depression symptoms. Because TMS is not a drug, it doesn’t cause the side effects that are often associated with antidepressants.
