Autism Spectrum Disorder (ASD) is a complex developmental condition that affects social interactions, speech and nonverbal communication, and restricted/repetitive behaviors. Autism is known as a “spectrum” disorder because there is a wide variation in the type and severity of symptoms. According to the Centers for Disease Control and Prevention, one in 59 children is estimated to have autism.
There is no one test that can detect Autism, rather several screening instruments are used to help with the diagnosis. One such screening tool is known as the MCHAT: Modified Checklist for Autism in Toddlers, Revised, which is designed to identify children 16 to 30 months of age who should receive a more thorough assessment. You can take this screening tool here.
If there is a concern that your Child is showing possible signs of Autism, then a diagnostic evaluation should be performed. A diagnostic evaluation should involve an interview and play-based testing performed by a psychologist, development-behavioral pediatrician or child psychiatrist.
