SIGN 145 Assessment, diagnosis and interventions for autism spectrum disorders

SIGN 145: Assessment, diagnosis and interventions for autism spectrum disorders provides recommendations on the identification of people with ASD, diagnosis, management and support for children, young people and adults with ASD.

The prevalence of ASD in children and adults is around 1% of the population in the UK. It can affect both males and females. There is an increasing understanding that autism spectrum disorder is a lifelong condition in which the core features persist whilst manifesting differently according to different age stages. Depending on the severity of autistic difficulties, ASD may not be evident as a presentation until adulthood, but may also be underdiagnosed due to coexisting conditions, family support, or masking of symptoms.

Prompt diagnosis and appropriate intervention, specialised educational programmes, and structured support may help a person with ASD maximise his or her potential.

This guideline supersedes SIGN 98: Assessment, diagnosis and clinical interventions for children and young people with autism spectrum disorders.
