The Food and Drug Administration (FDA) has cleared Nexstim’s ‘NBT’ system, a non-invasive brain stimulation system, for the treatment of major depressive disorder (MDD).

Previous studies have shown that TMS treatment may be an effective alternative to pharmacotherapy in patients with MDD who have failed drug therapy.
