Autism spectrum disorder (ASD) is a developmental disability that affects communication and behavior. It involves persistent deficits in social communication/interaction and restricted/repetitive behaviors. ASD is diagnosed based on symptoms in early childhood and their impact on functioning. Treatment may include applied behavior analysis, occupational therapy, and picture exchange communication systems. Attention deficit/hyperactivity disorder (ADHD) is a mental health disorder involving inattention, hyperactivity and impulsiveness. It is diagnosed based on symptoms present for at least six months. Treatment often involves behavioral psychotherapy, medication, or both to improve time management, organization and decrease distractions.
