Understanding Autism Spectrum Disorder (ASD): Assessment & Diagnosis

Asperger's syndrome is no longer a separate diagnosis, and is now considered part of the broader diagnosis of Autism Spectrum Disorder (ASD).

There is no one definitive test for ASD. A diagnosis of ASD is based on a comprehensive assessment of an individual's behavior and development. This assessment may include:

- A review of the individual's medical and developmental history

- Observations of the individual's behavior in different settings

- Interviews with the individual and their parents or caregivers

- Psychological testing

There are a number of screening tools that can be used to identify individuals who may be at risk for ASD. These tools can be helpful in prompting further assessment, but they are not diagnostic.

If you are concerned that someone you know may have ASD, it is important to seek professional evaluation. A qualified professional can provide a comprehensive assessment and make a diagnosis if appropriate.
