After quite some time I think I have found the best neutral definition for Autism. Autism is a disorder of neural development characterized by impaired social interaction and communication, and by restricted and repetitive behavior.
I saw this someplace and it hit me. I thought to myself “Finally!” There’s no hint of segregation, no directed blame, no excuses, no threatening verbiage, no use of words like retardation, no implications that it must run in the genes of your family somewhere, just a nice sentence with four normal words “disorder of neural development”. Thank you science community for giving people like my son some dignity.
