Autism Spectrum Disorder (ASD) is a neurological (brain) disorder that affects communication, social interaction, and behavior. Individuals with autism typically have difficulty understanding verbal and/or nonverbal communication, and learning appropriate ways of relating to other people, objects, and events. As its name implies, ASD is a “spectrum” disorder that affects individuals differently and with varying degrees of severity. No two people with ASD are the same. “If you have met one person with autism, you have met one person with autism.”
