This category includes autism spectrum disorder (ASD), obsolete terms for ASD, and disorders which result in ASD. It does not include common co-morbidities (e.g. ADHD), symptoms associated with ASD (e.g. caetextia), or disorders otherwise associated with ASD (e.g. social (pragmatic) communication disorder).
