It is thanks to great advances in the field of neuroscience, which allowed identifying dysfunctions in neural networks as the cause of many psychiatric and neurological diseases, that the number of indications for deep brain stimulation (DBS) has quickly expanded. Although the precise mechanism of action of DBS is unknown, this method probably works by influencing the neural pathways through stimulation of deep targeted brain nuclei which behave as "hubs" in these complex networks. Currently, there is growing interest on DBS' potential benefit, especially in the psychiatric field. This review intends to tackle the current and future psychiatric and neurological indications of DBS.

Deep brain stimulation (DBS) requires the surgical implantation of a system including brain electrodes and impulsion generator(s). The nuclei targeted by the stereotaxic implantation methodology have to be visualized at best by high resolution imaging. ⋯ DBS for movement disorders has a very good efficacy and a low albeit non-zero risk of serious complications. Complications related to the material are the most common.
