Asperger's syndrome: three cases and a discussion.

The recently revived academic interest in and controversy over the subject of Asperger's syndrome is briefly discussed. Gillberg & Gillberg's operational criteria for its definition are used to isolate three cases of the syndrome presenting over a single year to a mental handicap service. The cases are described in detail. Common themes and associations with the available literature are discussed. In all three cases, the struggle for clarity in the syndrome's nature or specificity in the literature is also reflected in aspects of their clinical management.
