How do I tell my doctor I think I’m autistic?

What this appointment is for

People often walk into this appointment expecting a judgement and leave disappointed, because a judgement isn’t usually what it produces.

NICE guidance in the UK describes a comprehensive autism assessment as undertaken by professionals who are trained and competent, team-based and drawing on a range of professions and skills where possible, and involving an informant or documentary evidence. That describes a specialist service. Where a health system is organised that way, a GP’s role in this conversation is generally referral rather than diagnosis.

That isn’t universal. Some systems and some clinicians work differently, some services accept self-referral, and a doctor may well have a view worth hearing. What’s reliably true is that a referral is a decision your doctor can make in the room, and a full assessment isn’t.

So it can help to ask for the thing that’s on the table. “Do you think I’m autistic?” invites an opinion. “I’d like to be referred for an assessment” names a decision.

Related evidence, and what it doesn’t cover

No study has looked at adults asking a GP for an autism referral. What exists is adjacent, and worth reading with that limit attached.

Au-Yeung and colleagues surveyed 420 adults in 2019 about mental health diagnoses they’d received and whether they agreed with them. Participants who identified as autistic or possibly autistic were more likely to report receiving mental health diagnoses than non-autistic participants, and less likely to agree with those diagnoses. Thematic analysis found two main reasons for disagreeing: that they felt their autistic characteristics were being confused with mental health conditions by healthcare professionals, and that they saw their mental health difficulties as arising from being autistic.

Participants attributed this to clinical barriers they’d experienced, including healthcare professionals’ lack of autism awareness and lack of communication, which they said prevented them from getting appropriate support. The study concluded that autism awareness training for healthcare professionals is needed.

This was a self-selected online survey about mental health diagnoses already received, not about referral requests. It describes what these 420 participants reported rather than how often this occurs, and it can’t tell you how your appointment will go. What it does show is that some autistic adults have experienced their characteristics being read as something else, which is a reason not to take scepticism as confirmation you’ve misjudged yourself.

A 2025 interview study by Au-Yeung, Freeth and Thompson found something related among 12 autistic adults diagnosed in adulthood, though it studied disclosure in general rather than medical appointments. Accessing support was one function disclosure served. Some participants also described not being believed and not having their needs met, which made them more cautious afterwards. Twelve people is a small qualitative sample and no basis for predicting your appointment.

What to bring

The suggestions below are editorial rather than tested. The reasoning behind them is that a clinician can act on specifics more readily than on a label.

A short written summary. One page, to hand over or read from. Appointments are short, and having it written means the important parts get said even if the conversation goes sideways.

Concrete examples, not traits. “I’m bad socially” gives a clinician little to work with. “I can’t follow conversations in groups of more than three, so I’ve stopped going to team lunches, and I take the long way to my desk to avoid the kitchen” gives them a picture.

Childhood, if you can reconstruct any. NICE guidance directs a comprehensive assessment to enquire into core autism features present in childhood and continuing into adulthood, and into early developmental history where possible. School reports, a parent’s recollection, things you were told about yourself. You don’t need this to ask for a referral, and its absence doesn’t disqualify you.

The cost. What you’ve stopped doing, what you avoid, what you spend recovering. Diagnostic criteria turn on impairment as well as traits, so this part is worth including rather than leaving implied.

Any screening scores, framed as context. An AQ or RAADS-R result is a reason you looked further, not a finding. NICE, the UK’s clinical guidance body, treats formal tools as aids to assessment rather than substitutes for one.

How to open it

One option is opening directly, on the reasoning that a short appointment leaves little room for a slow build. Something close to: “I think I may be autistic. I’ve looked into this seriously over the past while, not casually. I’d like to talk about being referred for an assessment.”

Three things are doing work there. You’ve stated the belief, signalled it isn’t a passing idea, and named the specific thing you want, which is the decision in front of them.

Booking a longer appointment where your system allows it, and saying what it’s about when you book, gives the conversation more room. That’s one of the few variables you control.

If speaking in the moment is hard, writing is a legitimate option. Emailing the practice beforehand, or handing over a page and letting the doctor read it while you sit there, are both reasonable.

If you’re not taken seriously

Some version of “you don’t seem autistic,” “everyone’s a bit like that,” or “but you have a job” is common enough that it’s worth having a response ready.

You can name the mismatch: that you’ve spent a long time learning to appear fine, and that appearing fine in a fifteen-minute appointment is the thing you’re best at.

You can ask a procedural question instead of arguing a clinical one: “What would I need to show to be referred?” That moves the conversation from their impression to a route.

You can ask for it to be recorded: “Could you note in my record that I requested an assessment and that it was declined?” A documented request gives you something to point at later.

You can see a different doctor in the same practice. Individual clinicians differ in their familiarity with adult autism.

And depending on where you live, you may be able to go around it—some specialist services accept self-referral, and private assessment is an option for people who can afford it. Those routes differ by country and by health system, and what your GP can or must do differs with them, so it’s worth finding out what applies where you are.

What changes once it’s in your notes

Worth thinking about before, rather than after.

What gets recorded, who can see it, how long it’s kept, and whether anything can be amended are governed by your country’s health-records rules and your provider’s policy, not by anything general this page could tell you. If that matters to your decision, your practice or health service can tell you what applies.

What’s worth deciding in advance is whether you want the conversation on file at all. Some people want exactly that, because a record is something later requests can refer back to. Others would rather ask what the options are before anything is written down. Both are reasonable, and it’s easier to choose deliberately than to discover the answer afterwards.

This page can’t tell you whether you’re autistic, and one appointment probably won’t either. What that appointment can do is start a process built to answer it properly, which is a smaller ask than it tends to feel like standing outside the surgery.
