Developmental perspective of the Gilles de la Tourette syndrome.

This paper concerned developmental perspectives of the Gilles de la Tourette Syndrome. Topics addressed included birth, developmental and family histories, and symptom picture. The neglected area of academic achievement was examined. Results of the first systematic investigation of neuro-psychological functioning of Tourette children undertaken in the United States was presented. Subjects were 13 diagnosed male Tourette patients between 10 and 13 yr. of age. Parents completed the Developmental History and Tourette Syndrome Questionnaires while subjects were administered the WISC-R, Wide Range Achievement Test, Bender-Gestalt, and Halstead Neuropsychological Test Battery for Children. There was no supporting evidence that pre-/postnatal trauma was significant in the etiology of the disorder. Again, evidence suggested a genetic component. Finally, academic difficulties appear related to the visuographic dysfunction noted on neuropsychological assessment.
