Autistic spectrum disorders 2: diagnosis and management.

As many as six in every 1000 children may be affected by an autistic spectrum disorder. The previous article of this two-part series discussed the distinction between autism, Asperger's syndrome and pervasive developmental disorder, and examined the assessment process. This article looks at potential differential diagnoses that must be considered, as well as conditions associated with autism. Many theories about the causes of autism have been suggested, including the MMR vaccine. Recent research has suggested that there is no link between the vaccine and autism. There is no cure for autism, but intervention and management techniques should be aimed at educating parents and carers about the disorder and behavioural interventions to aid the child's skills development.
