Involvement of immunologic and biochemical mechanisms in the pathogenesis of Tourette's syndrome.

Tourette's syndrome is a neurodevelopmental disorder clinically characterized by multiple motor and phonic tics. It is likely that a neurobiological susceptibility to the disorder is established during development by the interaction of genetic, biochemical, immunological, and environmental factors. This study sought to investigate the possible correlation of several immunological and biochemical markers with Tourette's syndrome.
