What is Autism?

Autism Spectrum Disorder (ASD) is a developmental disorder characterized by difficulties in social communication and interaction along with restricted, repetitive patterns of behavior, interests, or activities. Symptoms can change with development (becoming more or less severe) sometimes making a diagnosis difficult. The term “spectrum” reflects the wide variation in challenges and strengths possessed by each person with autism.
