Asperger's syndrome and Tourette syndrome: the case of the pinball wizard.

We review the English-language literature on Asperger's syndrome (AS), with particular reference to diagnostic criteria and differentiation from infantile autism and personality disorders, and describe six cases seen in practice: all met DSM-III criteria for 'atypical pervasive developmental disorder'. Three also developed Tourette syndrome: the co-occurrence of the two disorders, and methods of intervention, are discussed.
