Getting a diagnosis is for you, first and foremost. You are in charge of whatever information comes out of that.
You’re not obligated to disclose your diagnosis to everyone you meet, just as you’re not obligated to tell anyone about that tie-dye T-shirt you made at that fair when you were 11 that’s still at the back of a drawer.
Your diagnosis is yours. Any medical information, any personal detail that came out of your assessment belongs to you, and you decide who gets to hear about it.
You are not obliged to get a face tattoo letting everyone know you’re autistic, dyslexic, ADHD or anything else. Disclosing is your choice, and nobody can force you to do it.
Telling friends, family & coworkers
Some people tell close friends and family straight away. Some take months or years. Some never do. There is no correct timeline and no minimum number of people who need to know.
You might find that telling a few trusted people helps you process the diagnosis. You might find that you need time to sit with it yourself before you’re ready to share. Both are fine. So is changing your mind later.
If you’re worried about how people will react, that’s a separate question, and a valid one. We’ve written about that here.
What about work?
Your employer cannot require you to disclose a diagnosis. In the UK, the Equality Act 2010 places the obligation on your employer to provide reasonable adjustments to support you at work, without demanding personal details about your medical history. You can request adjustments without naming a specific condition. A conversation about what you need to do your job well does not have to include the words “ADHD” or “autism” if you don’t want it to.
That said, it would be naive to pretend the workplace is always safe. Legal protections exist, and they matter. But an employer who wants to push someone out can find ways that don’t reference a diagnosis directly. Knowing this helps you make informed choices about who you tell and when, based on what you know about your specific workplace.
Outside the UK
Similar workplace protections exist in many countries. In the US, the Americans with Disabilities Act (ADA) covers neurodevelopmental conditions.
In Australia, the Disability Discrimination Act 1992 applies.
In Canada, the Canadian Human Rights Act and provincial human rights legislation provide equivalent protections.
The specifics vary between jurisdictions, so check your country’s employment equality legislation for details.
What about doctors?
Whether your diagnosis is already in your medical record depends on how you were assessed. If you went through an NHS pathway or a Right to Choose provider, your GP will have received the final diagnostic letter. If you were assessed privately without a shared care arrangement, your GP may have no record of your diagnosis at all unless you’ve shared the report with them yourself.
Even when your GP has the letter on file, other clinicians you see won’t automatically know. NHS teams don’t routinely share full records with each other. A specialist, a locum GP, or an A&E doctor treating you on a given day is unlikely to have your ADHD or autism diagnosis in front of them unless you mention it.
This is worth mentioning proactively, and not just so it’s on the record. Your diagnosis can affect how medications interact, how you experience and report symptoms, how you respond to sensory-heavy procedures, and what kind of communication works best for you in a clinical setting. A doctor who knows you’re neurodivergent can adjust their approach. One who doesn’t may misread your presentation entirely.
What about the DVLA?
If you’re in the UK and you drive, your post-diagnostic letter may include a note about notifying the DVLA. The wording can feel alarming, but the actual obligation is more limited than it first appears.
The gov.uk guidance states that you must tell the DVLA if your ADHD or your ADHD medication affects your ability to drive safely. If your driving is not affected, you do not need to tell them. The same applies to autism: you must tell the DVLA if it affects your ability to drive safely, and if it doesn’t, you don’t need to do anything.
The keyword is “if.” This is a conditional obligation, not an automatic one.
Nothing changed about your brain the day you received your diagnosis. If you’ve been driving safely for years, you were already driving safely with ADHD. You just didn’t have the word for it yet, but a diagnosis alone does not make you a different driver.
If you’re outside the UK, your country will have its own driving authority and rules about medical conditions and driving. Check with your local authority for the guidance that applies to you.
How starting medication affects driving
The one period where driving deserves your attention is titration — the process of finding the right medication and dose after diagnosis.
During titration, your body is adjusting to a new substance. Depending on the medication and the dose, this can affect your focus, your energy levels, your sleep, and your reaction time. Some formulations wear off in the evening, leaving a gap in coverage that can show up as drowsiness or reduced concentration. These effects matter behind the wheel.
The research on this is reassuring in the longer term. Multiple studies show that being on a stable, well-matched ADHD medication improves driving performance compared to being unmedicated.123 Medicated drivers with ADHD perform similarly to drivers without ADHD in controlled road studies.4 The risk is higher when doses are too low, when medication wears off in the evening with short-acting formulations, or when doses are skipped.5
The adjustment period is the window to pay attention to. Talk to your prescribing clinician about how your medication might affect driving, particularly around timing and evening coverage. The gov.uk guidance says “ask your doctor if you’re unsure,” but your prescribing clinician during titration is the better person to ask — they know your medication, your dose, and your response to it. Once you’re stable on a dose that works, the evidence suggests you’re likely driving better than you were before, not worse.
Reading a list of ADHD-related driving risks after your diagnosis and retroactively panicking about every time you changed lanes is just unproductive and unnecessary. If you’ve been driving safely, you’ve been driving safely.
You’re still in charge
A diagnosis adds information to your life. It gave you language, context, and access to support. Who you tell, when you tell them, and how much you share stays with you.
