There is an overwhelming number of abbreviations, definitions, slang and idioms used in Autism, that it can be hard to keep up with. Use this list as a quick reference, it is in alphabetical order and has plenty of space to add information. This list originated from The Autism Community in Action website, I tweaked and updated it (it contained DSM-IV pieces). I last updated it in February, 2020. * Note: 11 pages in length.
