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.

It allows us to:
  • 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: learned coping strategies can hide traits well, sometimes even from the person themselves.
  • Women and girls, whose traits often present differently: presentations that don’t fit the traditional, often male-based picture are frequently missed or misdiagnosed.
  • Children and young people with complex or overlapping presentations: when traits overlap, separate assessments can miss the fuller picture needed for the right support at school and at home.
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.

What this includes:
  • 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.

3. Comprehensive ADHD Assessment

A full, structured ADHD assessment built around the DIVA-5, a well-validated diagnostic interview.

  • 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

Alongside both assessments, a psychologist leads a separate developmental history interview, drawing on the memories of a parent, caregiver or someone who’s 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 brought together and reviewed as a whole by our clinical team.

4. Outcome, report and feedback

Your case is reviewed by our clinical team together, so your outcome is considered from more than one perspective, not just a single clinician’s view.

We talk you through what we found and what it means, in plain language, with time for your questions and no rush. Because we’ve gone through everything with you along the way, there’s nothing at the end you won’t have seen coming.

You’ll get a short letter confirming your diagnosis the day after your assessment, so you’re not left waiting for the essentials. Your full written report follows within two weeks, ready to use with your GP, employer or university.

5. Begin your treatment plan

Your treatment plan is built around what actually works for you, not a fixed template. If medication is part of that, it’s arranged from within the clinic itself, so there’s no separate referral or search for a prescriber willing to take you on. Prefer to keep your own GP in the loop? We can set it up as shared care instead.

Medication is rarely the whole answer. We pair it with coaching from psychologists who specialise in ADHD and autism, focused on the everyday systems, routines and strategies that make the diagnosis actually useful day to day.

Can AuDHD Psychiatry prescribe medication?

Yes, for ADHD. If medication looks like the right option for you, our in-house prescribers can start and manage it directly, so you’re not left to track down your own prescriber after diagnosis.

  • Titration handled by our own prescribers, working with you to find the right dose
  • Monthly reviews for as long as you need them, once things are settled
  • Shared care with your GP instead, if you’d rather stay with them
  • ADHD and autism coaching alongside medication, for the day-to-day parts a prescription alone doesn’t solve

Autism & ADHD Assessment FAQs

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 can arrange shared care with them instead. 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.

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.

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.
