Which of the following is NOT one of the five categories of autism?

• A. Classic autistic disorder
• B. Asperger syndrome
• C. Attention Deficit Disorder
• D. Childhood Disintegrative Disorder

Answer: (C)

Attention Deficit Disorder (ADD) is not one of the five categories of autism spectrum disorders. The categories recognized under what was previously known as autism spectrum disorder include classic autistic disorder, Asperger syndrome, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified (PDD-NOS). The clarification here lies in understanding that ADD is classified as a separate neurodevelopmental disorder that primarily affects attention and impulse control, rather than social interaction and communication skills, which are key characteristics of autism spectrum disorders. Therefore, ADD does not fit within the diagnostic criteria or framework of autism. The other options listed are recognized types of autism within the spectrum reflecting various presentations and severities of the condition.
