Yeah, none of that has anything to do with the neurodivergent spectrum. Also, it isn't a scale from minor to major. It's an informal extension of the autism spectrum to include the other neurodivergent conditions, since there tends to be a lot of comorbidity across ASD, ADHD, ASPD, NPD, Dyslexia, Dyspraxia, etc. But, to be included in the spectrum, you have to have a neurodivergent condition. If you don't, that would make you neurotypical and that would put you in a different spectrum.

Edit: being neurotypical doesn't mean you should get help for your mental health. Everyone should, we're animals who made society and we're not equipped to handle all of... this gestures everywhere
