Repetitive transcranial magnetic stimulation (TMS) for medication-resistant depression.

The FDA has cleared a new device for treatment of major depressive disorder (MDD) resistant to antidepressant medication. The NeuroStar TMS System (Neuronetics) produces pulsed magnetic fields that can induce electrical currents in the brain. Unlike electroconvulsive therapy (ECT), it does not require anesthesia or induction of seizures. Other similar devices are under development.
