That may be true for ADHD, but autism diagnoses don't "unlock" any particularly sought-after prescription medication, so I don't think that can be the whole story. In kids, diagnoses do unlock accommodations in schools, but not so much for adults.
That's mostly true, but there is a huge overlap in ASD and ADHD diagnosis. It's very common to be diagnosed with both, and that expectation (from a healthcare provider's perspective) has implications.
