What to say, what to bring, and how to make sure you're taken seriously — whether you call them a GP, a PCP, or a family doctor.
For many adults who suspect they have ADHD, that first medical appointment is the biggest obstacle. Not because doctors are unhelpful, but because ADHD is a condition that hides well, and a short appointment tends to favour whoever knows how to present it clearly and specifically.
The most common mistake people make is describing their compensatory strategies rather than the underlying difficulty. 'I make lots of lists' sounds organised. What the doctor actually needs to hear is something closer to: 'Without lists I miss appointments, forget to pay bills, and have nearly lost jobs over it. Maintaining these systems takes so much energy that by the evening I'm completely depleted.'
Describe the impact on real, specific areas of your life — work, relationships, finances, sleep, self-esteem — and be concrete about incidents rather than general tendencies. 'I'm bad with money' is easy to dismiss. 'I've had three overdraft fees this year from forgetting to move money between accounts, despite setting reminders' is much harder to wave away.
The compensation is invisible to everyone but you. Your job in that appointment is to make it visible.
ADHD is a neurodevelopmental condition — by definition, its roots go back to childhood, even in people who weren't recognised or diagnosed at the time. Even if you coped reasonably well as a child, tell your doctor that these patterns have been present for as long as you can remember. This detail is clinically significant, and it's exactly what distinguishes ADHD from conditions that develop later in response to adult stress or specific life events.
A short written summary — even a single page — of your key symptoms and their real-world impact is far more effective than trying to articulate everything from memory in the moment, especially under the mild pressure of a time-limited appointment. If you've completed the ADHD Mirror assessment, the downloadable summary gives you a structured, clinically-framed document you can hand over or read from directly.
If you're writing your own, aim for specifics over impressions: three to five concrete incidents rather than general adjectives, roughly when the pattern started, whether a parent or sibling has ever been diagnosed with ADHD, and any old school reports that mention concentration, daydreaming, or underachievement. A doctor working from specifics can act far more confidently than one working from 'I think I might have ADHD.'
How you get from that first conversation to a formal specialist assessment depends heavily on where you live, and it's worth knowing your options before the appointment rather than during it.
In England, the Right to Choose pathway means you can request a referral to any qualifying registered ADHD service, not just your local NHS provider — this can reduce waiting times significantly, and it's worth naming explicitly if your GP isn't familiar with it. Scotland, Wales, and Northern Ireland have different systems, so check what applies locally.
In the United States, ask directly whether your insurance requires a referral for a psychiatric evaluation, and whether there are providers who specifically evaluate adults for ADHD who are in-network — this single question can save a significant amount of money and back-and-forth.
Wherever you are, it's reasonable to ask your doctor plainly: how does adult ADHD assessment work here — is it through you directly, a psychiatrist, or a specialist clinic — and what's the realistic waiting time? Most doctors would rather answer that clearly than have you find out the hard way.
You can request a second opinion, see a different doctor at the same practice, or in many places self-refer to a private specialist. A single appointment that doesn't result in a referral isn't the end of the road. Many people with ADHD end up having to advocate persistently to get taken seriously — which is, in itself, a particular kind of unfairness, given that persistence and self-advocacy under pressure are exactly the things ADHD tends to make hardest.
