title = "Is Development of Tourette Disorder a Marker for Improvement in Patients with Autism and Other Pervasive Developmental Disorders?",
abstract = "Fifty-nine patients were identified whose early history was consistent with infantile autism or other pervasive developmental disorders (PDD). Twelve of these patients, later in their history, developed symptoms consistent with Tourette disorder (TD). The group of patients who developed TD scored significantly higher on measures of IQ and receptive and expressive language. It is suggested that the development of the symptoms of TD subsequent to the onset of PDD may serve as a marker for improved developmental outcome and that children with PDD who also meet criteria for TD may constitute a distinct subgroup of children with PDD. Implications for diagnosis and management are discussed.",
