Accommodations usually (but not always) require diagnosis or confirmation by a doctor or other medical professional, and the law affords companies this discretion before granting one, whereas nonspecific 'neurodivergence' is often self-diagnosed.

All this aside, if you have e.g. crippling anxiety such that you can't make it through an interview unaided, you probably won't be successful in that job, whatever it is. Whereas a deaf person or someone in a wheelchair would have no long-term problem.
