AuDHD Assessment: ADHD and Autism Together

Page summary

A combined ADHD and autism (AuDHD) assessment looks at both conditions together in one coordinated pathway. It is for adults who think they may be ADHD, autistic, or both. The ADHD part uses the DIVA-5, and a separate developmental history interview runs alongside. The autism part is a 90-minute call using the ADI-R, adapted for online delivery. Both run online from home, with an optional informant interview. AuDHD Psychiatry sends an outcome letter the next day and the full report within two weeks. If ADHD medication could help, our in-house prescribers can start and manage it.

For adults who think they may be ADHD, autistic, or both. One joined-up assessment led by specialists in how the two overlap, online from home, with no GP referral needed.

Why it matters

Why a Combined Assessment?

Why choose a combined assessment?
Autism and ADHD often overlap, so assessing them separately can miss what’s really going on. A combined assessment gives one clear, joined-up picture, led by HCPC-registered psychiatrists and psychologists using recognised diagnostic tools.
  • Explore the overlapping and distinct features of autism and ADHD
  • Avoid a diagnosis pinned on the wrong condition
  • Give clearer, more meaningful recommendations
  • Replace two separate assessments with one joined-up process
Particularly helpful for
Overlapping traits can look different depending on who you are and when they show up. We see this often across:
  • Adults who’ve masked or compensated for years
  • Women and girls, whose traits often present differently
  • Children and young people with complex or overlapping presentations
What to expect from us
We take a neuro-affirming, whole-person approach from your first call through to ongoing support, not just a one-off report.
  • A joined-up assessment, usually completed within about a week
  • An optional informant call and a clear feedback session explaining the results
  • Input welcomed from partners, parents, carers, teachers or schools where it’s helpful, but never required
  • Ongoing aftercare, including medication management and follow-ups, not just a report

How the ADHD and Autism assessment works

When you choose

Your ADHD assessment

Book your assessments for times that suit you. Appointments are typically available within 10 days. Your ADHD assessment is a full, structured assessment built around the DIVA-5, a well-validated diagnostic interview, carried out online from home.
More about the assessment
Alongside both assessments, a psychologist leads a separate developmental history interview, drawing on the memories of a parent, caregiver or someone who has known you a long time. Each part is led by a different member of our team: a clinical or counselling psychologist leads the main assessment, with a second psychologist or nurse, and everyone’s findings are reviewed as a whole by our clinical team.
  • How ADHD shows up for you now, and growing up
  • Focus, energy, emotional regulation and everyday life
  • Carried out to a standard recognised by GPs, employers and universities
When you choose

Your autism assessment

A 90-minute call with a consultant psychologist who is neurodivergent themselves, carried out online from home.
Optional informant interview
If you would like, we can hold a separate interview with someone who knows you well. It is optional and never required. It can be a partner, parent, sibling or close friend, and they don’t need to have known you as a child. It adds another perspective on how autism shows up in your everyday life, and where they knew you growing up, it also helps us understand your early development. If there is no one you would like to involve, we can still carry out a thorough assessment using your own account, our clinical observations and questionnaires.
  • Your experiences and history across work, education, relationships and everyday life
  • The ADI-R, adapted for online delivery, including masked traits, not stereotypes
  • A collaborative conversation, not a sudden verdict
The next day

Questions and answers

Autism & ADHD Assessment FAQs

Quick answers to the questions people ask us most before booking.

Can I get an ADHD and autism assessment together, or do they need to be separate?

Yes. ADHD and autism overlap significantly, and assessing them separately can miss how they interact in real life. Our combined AuDHD assessment brings both together in one coordinated pathway, so nothing gets missed and you don’t need to repeat your history twice. If you’d rather focus on just one, we also offer standalone ADHD and autism assessments.

Is there a single test for ADHD and autism?

No single test can diagnose either condition on its own. Instead, we use a structured combination of clinical interviews, validated questionnaires, and behavioural observation, carried out by a multidisciplinary team of psychologists and psychiatrists. This helps us tell ADHD and autism apart from each other, and from conditions they’re often confused with, such as anxiety or sensory processing difficulties. Every assessment follows NICE guidance and is diagnosed against the DSM-5 criteria used across the UK and internationally.

Do I need a GP referral to book?

No, a GP referral isn’t required. You can book any of our assessments directly through our website, and we’ll confirm your appointment straight away, with no waiting for a referral or approval from anyone else.

How soon can I be seen?

You’ll typically be seen within a week of booking, not the months-long waits that are common elsewhere. Once your appointment is confirmed, we’ll guide you through everything you need beforehand, including any forms or questionnaires, so you’re fully prepared when the day arrives.

Do you only see patients in a certain part of the UK?

No – we’re a fully online service, so it doesn’t matter where in the UK you’re based. Assessments are carried out over video call by the same clinicians and to the same clinical standard as an in-person appointment, without the need to travel or wait for a local service near you.

Do I need someone who knew me as a child to take part (an informant)?

It isn’t a strict requirement. Input from someone who knew you growing up, such as a parent, sibling, or close friend, can add helpful context, particularly for an autism assessment where early developmental history matters. If that isn’t possible for you, we can still carry out a thorough assessment using your own account, our clinical observations, and any other information available to us.

What if I mask my symptoms during the assessment?

This is a common concern, and it’s something our clinicians are trained to look out for. Masking – consciously or unconsciously hiding traits to appear more ‘typical’ – is common in both ADHD and autism, especially in adults who’ve spent years compensating. We don’t rely only on how you present on the day; we also draw on your lifelong history, questionnaires, and, where available, informant input. If you know you tend to mask, it’s worth mentioning this to your clinician directly, as it helps us build the fullest possible picture.

What happens if I don’t receive a diagnosis?

We’ll always talk you through the results in detail. If we don’t find enough evidence for ADHD or autism, we’ll explain our reasoning and discuss other possible explanations for the difficulties you’ve been experiencing. Where it would help, we can also point you toward other appropriate support, whether that’s a referral back to your GP or another service that makes more sense for you.

Will my report be accepted by the NHS, my employer, school, or Access to Work?

Yes. Our reports are written to NICE-aligned clinical standards and are accepted by the NHS, as well as by schools, employers, and Access to Work. That said, how an individual organisation chooses to act on a report is ultimately down to their own policy, so it’s worth checking directly with them if you have a specific requirement.

What treatment and support is available after diagnosis?

Your options are discussed with you as part of a personalised care plan after diagnosis. If medication could help, you won’t need to go and find your own prescriber – our in-house prescribers work through titration with you directly, starting at the right dose and adjusting it together, then continue reviewing and prescribing every month afterwards. If you’d rather stay with your GP, we work with GPs to offer shared care instead, if the GP agrees. Alongside medication, we also offer dedicated ADHD and autism coaching, giving you practical, day-to-day support for the parts of life a diagnosis alone doesn’t solve.

Is shared care with my GP guaranteed?

No. Shared care depends on your GP agreeing to take over prescribing once your dose is stable, and some GPs and areas don’t offer it. We’ll share your report and treatment plan and ask your GP, but the decision is theirs. If your GP says no, you can carry on with private prescribing through us, and we’ll tell you the costs upfront.

What if I’ve already been assessed elsewhere?

If you’ve already had an assessment elsewhere, we can review your existing report and talk through your options. That might mean a second opinion, ongoing support, or shared care going forward – whatever’s most useful for you.

Do you offer payment plans?

Yes. We offer payment plans through Klarna, letting you split the cost into 3 monthly payments, so cost doesn’t have to be a barrier to getting assessed.
