Autism Attributes from Autism Canada
As Early as 18 months
Research has found that Autism Spectrum Disorders (ASDs) can sometimes be detected at 18 months or younger. By age 2, a diagnosis by an experienced professional can be considered very reliable. However, many children do not receive a final diagnosis until they are much older. This delay means that children with an ASD might not get the help they need. The earlier an ASD is diagnosed, the sooner treatment can begin.
Developmental Screening Tools
Screening tools are designed to help identify children who might have developmental delays. Screening tools do not provide conclusive evidence of developmental delays and do not result in diagnoses. A positive screening result should be followed up with your child’s health care provider immediately if you think something is wrong.
Types of Screening Tools
There are many different developmental screening tools that may be administered by our professionals. These include:
Ages and Stages Questionnaires (ASQ)
Communication and Symbolic Behavior Scales (CSBS)
Parent’s Evaluation of Development Status (PEDS)
Modified Checklist for Autism in Toddlers (M-CHAT)
Screening Tool for Autism in Toddlers and Young Children (STAT)
Observation tools such as the Autism Diagnostic Observation Schedule (ADOS-G)
The Childhood Autism Rating Scale (CARS)
The Autism Diagnostic Interview – Revised (ADI-R)
This list is not exhaustive, and other tests are available.
For your convenience, Autism Canada has four online screening tools available based on the age of the individual being screened. Click here to be redirected to the online screening tools.
