New Methods of Brain Stimulation Are Improving Research and Therapy in Obsessive-Compulsive Disorder

Over the past decade, new functional neuroimaging tools have enabled researchers to identify the specific brain regions involved in obsessive-compulsive disorder (OCD). More recently, researchers have perfected several new techniques for stimulating the brain. With some exception's, these new brain stimulation techniques are regionally specific and less invasive than older methods. As a class, these "somatic interventions" build on prior neuroanatomic information about OCD. This article reviews the past and current status of these brain stimulation methodologies, which promise to revolutionize neuropsychiatric research and therapy over the next 10 to 20 years. As the brain circuits in. OCD and the pharmacology within those circuits become better understood, these brain stimulation techniques hold particular promise in. helping to understand and perhaps treat OCD.
