Slightly different diagnostic definitions are used in other countries.

Where did autism come from?
The word autism comes from the greek word "autos" whose meaning was first established by Eugen Bleuler. Autism as it is known today can be drawn back to the late 1930's. Two separate psychiatrists used the word autism to describe the patients they were studying in their own clinical research. Victor, the Wild Boy of Aveyron, was found deep in the woods of Central France. He was non-verbal amongst his teenage years, and his case was widely popular among society for its time. Such cases brought awareness to autism, and more research was conducted on the natural dimensions of human behavior. The discussion of autism prior to the twentieth century is one that brings about much controversy. Without researchers being able to meet a consensus on the varying forms around the condition, there was a lack of research being conducted on the disorder. Discussing the syndrome and its complexity frustrated researchers. Controversies have surrounded various claims regarding the etiology of autism spectrum disorders. In the 1950s, the " refrigerator mother theory " emerged as an explanation for autism. The hypothesis was based on the idea that autistic behaviors stem from the emotional frigidity, lack of warmth, and cold, distant, rejecting demeanor of a child's mother. Naturally, parents of children with an autism spectrum disorder suffered from blame, guilt, and self-doubt, especially as the theory was embraced by the medical establishment and went largely unchallenged into the mid-1960s. The "refrigerator mother" theory has since continued to be refuted in scientific literature, including a 2015 systematic review which showed no association between caregiver interaction and language outcomes in ASD.

Broad spectrum approach
A spectrum disorder is a mental disorder that includes a range of linked conditions, sometimes also extending to include singular symptoms and traits. The different elements of a spectrum either have a similar appearance or are thought to be caused by the same underlying mechanism. In either case, a spectrum approach is taken because there appears to be "not a unitary disorder but rather a syndrome composed of subgroups". The spectrum may represent a range of severity…
