The shift from DSM-IV to DSM 5 reflects recognition that for some children, the deficits in reciprocal social interaction may not manifest until expectations for social roles, demands and interactions exceed limited capacities. The DSM 5 emphasis on the limitation and impairment of everyday activities focus on two hallmark characteristics of a person with autism: communication and social challenges, and an abnormal focus on a specific topic or interest (Gobbo, & Shmulsky, 2012).

Autism Spectrum Disorder now encompasses former DSM-IV distinct categories of “classic” Autism, Asperger’s Disorder, a rather loosely formulated disorder referred to as Pervasive Development Disorder (PDD), and Childhood Disintegrative Disorder.

Autism is a neurodelvelpomentn group of diseases, commonly known as a spectrum of disorders. Inside this spectrum is:
