I would have been diagnosed about 13 years ago under the ICD, and likely the writing on my record would have been under NICE guidances as I'm not in the US. The diagnosis was indeed HFA, and it was outlined to me how that was ''autism without intellectual disability, but not Aspergers.'' This is a historical diagnosis that was yeah, later changed to ''Autism Spectrum Disorder'' and assigned a level. Guidances aren't equally shared amongst countries and medical systems.
