Transcranial magnetic stimulation has been applied in a growing number of psychiatric disorders as a putative treatment. As a focal intervention that may exert lasting effects, TMS offers the hope of targeting underlying circuitry and ameliorating the effects of psychiatric disorders. The ultimate success of such an approach depends upon our knowledge of the neural circuitry involved, on how TMS exerts its effects and on how to control its application to achieve the desired effects. Current challenges in the field include determining how to enhance the efficacy of TMS in these disorders and how to identify patients for whom TMS may be efficacious.
