Abstract:
To explore suggested relationships between involuntary motor disorders and obsessive-compulsive disorder (OCD), we evaluated obsessive-compulsive characteristics in patients with idiopathic spasmodic torticollis (IST). Twenty-two patients with IST had significantly higher scores than 29 age- and sex-matched healthy controls on the Yale-Brown Obsessive-Compulsive Scale and the obsessionality subscale of the Symptom Checklist-90-Revised. The IST patients also had higher (though not significantly so) scores on the Maudsley Obsessive-Compulsive Inventory. Their Beck Depression Inventory scores were likewise higher than those of controls. These results provide additional support for the theory of a link between basal ganglia disorders and psychiatric disorders.
