If you’re reading this after an appointment that didn’t go the way you hoped, that’s a genuinely frustrating and disheartening place to be — and it’s common enough that it’s worth its own page. This isn’t a sign you were wrong to bring it up, and it isn’t a sign you have to give up.
This page is educational, not medical or legal advice. It doesn’t replace speaking with a qualified professional, and it can’t guarantee any particular outcome with any provider.
Why this happens so often
It’s not usually personal, even though it feels that way in the room. A few real, recurring reasons:
- Diagnostic criteria were built around childhood presentations, mostly in boys. A provider trained on those criteria may genuinely not recognize an internalized, masked, or adult-onset-appearing presentation as ADHD or autism, even when it clearly is.
- “You did well in school” or “you’re clearly capable” gets treated as evidence against, rather than a sign of a strong coping system. Academic or professional success is frequently used to argue against a diagnosis, when it often reflects exactly the kind of compensatory strategy that makes these conditions harder to spot — the same reason we built the personal-system follow-up into our self-assessment.
- Appointment time is short. A 10–15 minute primary care visit isn’t long enough to properly explore a lifetime pattern, and some providers will (unhelpfully) default to “you seem fine” rather than “I don’t have time to assess this properly.”
- Not every provider is trained in adult ADHD or autism specifically. General practice covers an enormous range of conditions; a provider can be excellent generally and still have limited specific training here.
None of this makes the dismissal fair or acceptable — it just means the fix is usually “find the right provider,” not “convince this one,” which is a different and often less exhausting goal.
Before your next appointment
- Bring something written. A printed self-assessment summary, a short list of specific examples, or even brief notes read from your phone all help — dismissal is easier when your concerns are vague in the moment, and harder when they’re specific and already on paper.
- Lead with function, not just feelings. “This is affecting my job performance and two close relationships” tends to land more seriously than “I think I might have ADHD.”
- Ask directly for what you want. “I’d like a referral for a formal ADHD/autism assessment” is a clearer ask than describing symptoms and hoping the provider connects the dots to a referral on their own.
- Consider requesting a longer appointment. Some practices offer extended visits for more complex concerns — it’s a reasonable thing to ask for when booking.
If it doesn’t go well anyway
- You’re allowed to ask why, directly. “Can you help me understand what led you to that conclusion?” is a fair, calm question — and the answer will often tell you whether this is a provider worth persisting with or one worth leaving.
- You’re allowed to ask for the reasoning in writing, especially if you may want to seek a second opinion or use it to support a future referral request elsewhere.
- A second opinion is a normal, reasonable step, not an act of defiance. Many adults who are eventually diagnosed were dismissed at least once first.
- Where a formal “choice” mechanism exists, use it. In England, for example, the NHS Right to Choose scheme lets your GP refer you to an alternative approved provider if your local pathway isn’t working for you — see our resource directory for details relevant to your country.
- A specialist referral can sometimes bypass the issue entirely. Asking specifically for a referral to a psychiatrist, psychologist, or clinic that focuses on adult ADHD or autism, rather than relying on a generalist’s judgment call, changes who’s actually making the assessment.
Common dismissive comments, and how to respond
“Everyone’s a little ADHD/autistic sometimes.”
“I understand traits exist on a spectrum, but what I’m describing has been a consistent, significant pattern affecting my work and relationships for years — not an occasional experience. I’d like to be formally assessed rather than have that ruled out in this conversation.”
“You did fine in school / you have a good job, so it can’t be that.”
“I’ve actually managed that by building a lot of personal systems and working much harder than it looks like from the outside — the cost of that has been significant, even if the results looked fine. I’d still like a formal assessment.”
“You’re clearly too high-functioning for that.”
“I’d rather not rule it out based on how well I’m coping — what I’m asking for is an assessment that actually looks at the underlying pattern, not just how well I’ve learned to hide it.”
“That sounds more like anxiety/depression.”
“It’s possible both are going on — they’re not mutually exclusive, and I’d like both properly assessed rather than assuming one explains the other.”
When to walk away and try someone else
If a provider won’t refer you, won’t explain their reasoning, or dismisses you without engaging with the specifics you’ve brought — that’s useful information about that provider, not a verdict on your concerns. Bringing your notes and your self-assessment summary to a different provider entirely is a completely reasonable next move, and often the one that actually works.
For where to look next, our resource directory lists organizations by country that can point you toward providers who assess adults specifically, and our assessment-logistics page walks through what a thorough evaluation should actually look like once you’re in the room.
