Sensory-Motor Aspects of Obsessive-Compulsive Disorder

This article presents an overview of sensorymotor aspects of obsessive-compulsive disorder (OCD). These phenomena have received less attention than obsessions and compulsions, but are nonetheless important in the development, maintenance, phenomenology, and treatment of the disease. In many individuals, seemingly disparate sensory-motor symptoms can be conceptualized as part and parcel of OCD. Sensory-motor aspects are discussed within the context of faulty information processing and related to neuropsychiatric systems characteristic of OCD. As the pathophysiology of OCD is highly extensive, not all sensory-motor symptoms discussed here will be observed in every individual.
