Autism Spectrum Disorder

People with autism face communicative and social challenges. Some individuals with autism may communicate verbally, while others may not speak at all and require an augmentative or alternative communication system. They often have difficulty identifying social cues and making conversation. People with autism typically demonstrate repetitive behaviors and have restricted interests. These individuals may have difficulty accepting changes in their schedule or routine.

Autism is present throughout the diagnosed person’s lifetime and sometimes runs in families. While the medical community uses the term “autism” in reference to a disorder or disability, some consider autism a difference rather than a disability.
