Vagus nerve stimulation and neurotrophins: a biological psychiatric perspective
Since 2004, vagus nerve stimulation (VNS) has been used in treatment-resistant or treatment-intolerant depressive episodes. Today, VNS is suggested as possible therapy for a larger spectrum of psychiatric disorders, including schizophrenia, obsessive compulsive disorders, and panic disorders. Despite a large body of literature supports the application of VNS in patients’ treatment, the exact mechanism of action of VNS remains not fully understood.
