[The Value of Deep Brain Stimulation in Difficult-To-Treat and Treatment-Refractory Depression]

The Value of Deep Brain Stimulation in Difficult-To-Treat and Treatment-Refractory Depression Abstract: Deep Brain Stimulation ("DBS") is a minimally invasive, neurosurgical and hypothesis-driven therapeutic procedure for permanent local regulation of pathological circuits. While depression represents a heterogeneous syndrome with multifactorial etiopathogenesis, neuroscience research is advancing evidence to identify network-level mechanisms that play an important role in the pathophysiology of depression. In the following article, we will review the role of DBS in treatment-resistant or difficult-to-treat depression. The aim is to increase the awareness of DBS and to discuss the challenges of its therapy and implementation.
