I've asked this question myself. Seems the answer is they'll treat whatever symptoms you have regardless of your diagnosis. If you get depressed they'll dispense an anti-depressant. If you get anxious they'll order an anti-anxiety. The diagnosis itself doesn't make you eligible (or ineligible) for social benefits. Your inability to work, or go to school, or maintain a relationship would hedge less on your named diagnosis and more on your obvious symptoms like social anxiety, inability to address groups of people, visual and/or auditory issues that could be exacerbated in certain working environments, etc.
