What are the two core domains affected in autism spectrum disorder?

• A. Delays in motor milestones
• B. Restricted interests only
• C. Abnormalities in social interaction and communication and patterns of behavior, interests and activities
• D. Learning disabilities

Answer: (C)

Autism spectrum disorder is defined by persistent deficits in social communication and interaction, and by restricted, repetitive patterns of behavior, interests, or activities. The social-communication domain includes difficulties with social reciprocity, using and understanding nonverbal cues, and forming and maintaining relationships. The restricted and repetitive domain covers repetitive movements, insistence on sameness, highly restricted interests, and sensory sensitivities. These two domains together explain the characteristic presentation, while other options describe features like motor delays or learning disabilities that may occur but do not define the condition.
