The main contributors of the chronicity and unresponsiveness to treatment of these disorders are our incomplete understanding of the pathophysiology of the diseases, our limited therapeutic arsenal and our phenomenological approach in diagnosis (Nahas, 2010). Several biomarkers using neuroimaging techniques, biochemical and genetic tests have been identifi ed, but most lack exact sensitivity or specifi city. The fi eld of neuromodulation is advancing at a rapid pace. Brain stimulation techniques are promising for treatments of many neuropsychiatric diseases including depression, schizophrenia, Parkinson’s Disease (PD), Obsessive-Compulsive Disorder (OCD) and Tourette’s Syndrome (TS). They also aid in the development of other new treatments that incorporate neurogenesis via stem cells, viral vectors and transgenic cells. Although much is known about their action on brain networks, their exact therapeutic mechanism is yet to be agreed upon. This chapter focuses on two specifi c techniques at the opposite spectrum of invasiveness: Deep Brain Stimulation (DBS) and Transcranial Magnetic Stimulation (TMS).
