Asperger's syndrome and autism: the case for a connection

Abstract

There is considerable disagreement on the classification of Asperger's syndrome and its relationship to autism. Unlike autism, Asperger's is not usually recognised before 30 months of age, and speech delay is not typical. However, if a child exhibits all the symptoms of autism apart from these two features, are these sufficient grounds for withholding a diagnosis of autism? This paper describes four boys and their father who, by presenting at various points on the autistic/Asperger spectrum, embody this dilemma for the diagnostician. The implications for research and clinical practice are discussed.
