I had a colleague that people assumed was on the autism spectrum, this somehow came up years later over drinks to which he responded "maybe I should ask my doctor, I always assumed I was just an asshole"
I apologize for the specificity of the nit I'm about to pick, but the "spectrum" part of Autism Spectrum Disorder does not mean that every person is on it! ASD has very specific diagnostic criteria (https://www.cdc.gov/ncbddd/autism/hcp-dsm.html) according to which an individual is either diagnosed with ASD or not.
If you have 95% of the symptoms of autism, but not 100%, what does that mean? Sorry get fucked you're not autistic. You're close, but not quite! See you in six months.
At the end of the day the treatment path will be the same (ie, there is none, learn to accept yourself and manage your neurodivergence like the rest of us)
