Has the definition of Autism been the same throughout the years?
This documentary mentioned that the rates of Autism diagnoses are increasing, and it made me wonder: are they still using the same definition of Autism as the one from decades ago?
If you go on YouTube and look up Autism-related videos you will find people who claim to have Autism; yet they are vocal, and don't self-harm. That's certainly different from the cases shown in the film.
Could the increase in Autism have to do with it being made into a "spectrum" with a looser definition?
