Infantile autism: diagnosis and treatment.

This article reviews recent developments in the diagnosis and treatment of infantile autism. Autism is currently conceptualized as a behavioural syndrome with multiple biological aetiologies. A diagnosis of infantile autism implies that a thorough neurobiological investigation is called for. The core psychological deficit necessary and sufficient to cause central autism symptoms is gradually being defined. The multiple aetiologies of autism will lead to multiple treatment in the future. At the present stage structured education and behaviour modification provide the cornerstones of any treatment programme.
