The word ‘spectrum’ is used because the range and severity of the difficulties people with an ASD experience can vary widely. ASDs include autistic disorder, Asperger’s disorder and pervasive developmental disorder – not otherwise stated, which is also known as atypical autism. Sometimes the word “autism” is used to refer to all ASDs. (Aspect Website definition)
