More adults than ever before are seeking clarity about their ADHD, their Autistic traits, or both. Some arrive at this after years of feeling out of step with the world around them. Some are prompted by a child's diagnosis, recognising familiar patterns in themselves. Others have always known they were different and are simply looking for language, and a formal process, that fits.
Whatever the route you take, one question comes up again and again: how do you find an assessment, a therapist, or a coach who will genuinely understand you, rather than one more professional you have to explain yourself to all over again? For many neurodivergent people, this search has traditionally relied on word of mouth, informal community recommendations, and a fair amount of trial and error, often after disappointing experiences with practitioners who meant well but simply did not understand what they were looking at. Directories such as Neurodivergent Practitioners exist precisely for this reason, connecting neurodivergent people with practitioners whose lived experience sits alongside their professional training.
This guide looks at what a genuinely neurodiversity-affirming assessment involves, why the training behind that assessment matters, and how to find support that respects who you are rather than treating your neurodivergence as something to be fixed. Organisations such as Global ADHD Network work on the clinical training side of this picture, equipping healthcare professionals with the structured, evidence-based skills needed to assess ADHD accurately, work that sits alongside, rather than in place of, the lived-experience understanding that practitioners on this directory bring to their practice.
A neuroaffirming approach understands neurodivergence, whether that is being Autistic, having ADHD, being AuDHD, dyslexic or dyspraxic, as a natural form of human variation rather than a disorder to be corrected. This sits alongside what is often called the social model of disability: a great deal of what makes daily life hard for neurodivergent people comes from environments, systems and expectations built without them in mind, rather than from the neurodivergence itself.
This does not mean that difficulty is not real. Many neurodivergent people experience genuine, sometimes significant, challenges that are not simply a product of an unaccommodating world. A neuroaffirming approach holds both truths at once: that the world creates much of the disadvantage neurodivergent people face, and that some difficulty lives in the person's own experience and deserves support in its own right. Good practitioners, and good assessors, work from this fuller picture rather than a narrow, deficit-only view, and it is this balance, rather than either extreme on its own, that tends to produce support people actually find helpful.
Adult identification of ADHD and autism has risen sharply in recent years. Greater public understanding, more visible role models, and a wave of social media content describing lived experience have all played a part. So has a growing recognition that ADHD and autism were, for decades, poorly understood in women, in people of colour, and in anyone whose presentation did not match narrow, often White and male, diagnostic stereotypes from earlier research.
Many adults describe a lifetime of masking, the conscious or unconscious effort to hide or suppress natural traits in order to fit in, and the exhaustion that comes with it. For some, identification brings relief and a new framework for understanding a lifetime of experiences. For others, it opens the door to formal support, workplace adjustments, or treatment options that were previously inaccessible without a diagnosis. Either way, arriving at this point is rarely a single moment. It is usually the result of years of small observations, comparisons and questions finally coming together into a clearer picture.
Not every neurodivergent person pursues, wants, or has access to a formal diagnosis, and self-identification is a valid and increasingly recognised part of the neurodivergent experience. Cost, long waiting lists, and past experiences of not being believed by clinicians all shape why someone might choose self-identification over a formal process, or hold both at once while deciding what feels right for them.
That said, formal diagnosis still matters for many people, whether for access to medication, legal protections at work, educational support, or simply the personal clarity of an external, structured assessment. Good practitioners respect wherever someone is in this process, without treating self-identification as lesser or formal diagnosis as the only legitimate outcome.
A thorough, affirming ADHD or autism assessment involves considerably more than a single questionnaire. It typically includes a detailed developmental history, structured clinical interviews, validated assessment tools used to support rather than replace clinical judgement, and consideration of how traits show up across different areas of life, such as work, relationships and daily routines.
What sets an affirming assessment apart is not just the clinical rigour behind it, but how the person is treated throughout the process. This includes:
It is also worth knowing that a single appointment is rarely enough for a thorough assessment. Most reputable services involve more than one session, sometimes spread across several weeks, allowing the assessor to build a fuller picture rather than reaching a conclusion from a single snapshot in time. If a service offers a diagnosis after one brief conversation with no structured tools or developmental history gathered, that is generally a sign to look elsewhere, however tempting the shorter waiting time might feel.
Masking describes the conscious or unconscious effort many neurodivergent people make to hide or suppress natural traits in order to appear more neurotypical, whether that means forcing eye contact, rehearsing conversations in advance, or suppressing stimming. Masking can become so automatic over years that a person loses touch with which behaviours are genuinely theirs and which were built to get through the day unnoticed.
Sustained masking carries a real cost, often described as neurodivergent burnout: a state of exhaustion, reduced capacity, and sometimes loss of previously manageable skills, brought on by the ongoing effort of functioning in an unaccommodating environment. This matters for assessment because masking can make traits harder for an assessor to spot, particularly in adults who have masked for decades, and it matters for ongoing support because recovery from burnout often requires reducing masking rather than simply resting. A neuroaffirming practitioner understands both dynamics and factors them into how they work with a client, rather than mistaking a well-masked presentation for an absence of difficulty.
Neurodivergent people are never only neurodivergent. Race, gender, sexuality, faith, migration status and class all shape how someone experiences their neurodivergence, and how they are met, or missed, by services built around narrow assumptions. Historically, diagnostic research and clinical training leaned heavily on a narrow demographic, which contributed to widespread underdiagnosis among women, people of colour, LGBTQ+ people and others whose presentation did not match that original picture.
A genuinely neuroaffirming practitioner recognises this history and actively works against it, rather than assuming a single, universal presentation of ADHD or autism. For multiply marginalised neurodivergent people, finding a practitioner who understands these overlapping experiences, rather than treating neurodivergence in isolation from the rest of a person's identity, can make the difference between feeling truly seen and feeling only partially understood.
Clinical support is only part of the picture. Many neurodivergent people describe peer community, whether online or in person, as equally significant to their wellbeing and self-understanding. Connecting with others who share similar experiences can validate what formal assessment alone cannot always provide: the sense of not being alone, and practical, lived-experience strategies that no textbook covers in quite the same way.
Peer-led support groups, often run by neurodivergent facilitators themselves, offer a different kind of space to therapy or coaching, one built on shared experience rather than a purely professional relationship. For many people, especially those newly identified or newly diagnosed, finding this kind of community alongside formal support makes the whole process feel considerably less isolating.
In the UK, ADHD and autism assessments are generally available through the NHS or privately. NHS assessment usually starts with a GP referral, and the NHS guidance on getting an autism assessment sets out this process, while ADHD assessment follows a broadly similar referral pathway into a specialist service. Private assessment usually allows self-referral and tends to be considerably faster, though it comes at a personal cost.
Whichever route is chosen, the assessment itself should be grounded in recognised clinical guidance. The NICE guideline on ADHD diagnosis and management and the NICE guideline on autism assessment for adults both set out the structured process a rigorous assessment should follow, regardless of whether it takes place within the NHS or privately.
The words a practitioner or an assessment uses are not a small detail. They shape how a person is met from the very first sentence they read. Identity-first language, such as "Autistic person" rather than "person with autism," reflects what Autistic communities have consistently told researchers they prefer, though preference does vary by culture and individual, and the right approach is always to follow how a person describes themselves.
Functioning labels, such as "high functioning" or "low functioning," tend to obscure more than they reveal, often minimising real support needs on one end and overlooking genuine strengths and autonomy on the other. Person-first language remains more common for experiences such as OCD, PTSD and Tourette's, where community preference has generally leaned that way. None of this is about following a rigid script. It is about practitioners genuinely listening to how the people they support describe themselves, and letting that shape the language they use in return.
Lived experience and clinical training are not competing forms of expertise. They work best together. An assessor who understands neurodivergence from the inside brings a depth of insight that no textbook can teach, while structured clinical training ensures that an assessment is thorough, consistent, and grounded in current evidence rather than outdated assumptions.
This matters because ADHD and autism research has moved quickly over the past decade, particularly around how both conditions present in adults, in women, and in people navigating co-occurring experiences. An assessor who has not kept their training current risks missing presentations that do not fit older, narrower diagnostic pictures, which historically led to many Autistic and ADHD adults, especially women and people of colour, being overlooked entirely.
Global ADHD Network is an independent, international training and professional development organisation for healthcare professionals, clinicians, educators and therapists working with ADHD and neurodevelopmental conditions. We provide CPD-certified ADHD training courses designed to equip doctors, nurses, pharmacists, psychologists, occupational therapists and other allied health professionals with the clinical knowledge and practical skills needed to assess, diagnose and manage ADHD in adults and children.
Training covers areas including structured ADHD assessment methodology, medication management, and structured autism assessment interviewing for clinicians who also assess Autistic traits. Global ADHD Network is listed on Neurodivergent Practitioners under Diagnostic Services, and courses are delivered entirely online, reaching clinicians across the UK and internationally.
ADHD and Autistic traits frequently co-occur, an experience often described informally as AuDHD. People who are AuDHD sometimes describe their ADHD and Autistic traits as pulling in different directions internally, for example a need for routine sitting alongside a mind that resists structure, which can make self-understanding, and assessment, more complex than looking at either experience in isolation.
A thorough assessment should always consider this overlap rather than assuming a single explanation for someone's experience. Assessors who understand AuDHD are better placed to avoid the common pattern where one set of traits is identified while the other is missed entirely, something many AuDHD adults describe happening to them, sometimes more than once, before they received a fuller picture.
This pattern of missed overlap is not simply a historical accident. Diagnostic criteria for ADHD and autism were developed largely as separate systems, and for a long time clinicians were actively discouraged from diagnosing both conditions in the same person. That guidance has since changed, but its legacy lingers in how some clinicians still approach assessment, which is part of why finding an assessor who is genuinely up to date on current understanding of AuDHD, rather than working from decades-old training, makes a real difference to the accuracy of the outcome.
An assessment or identification is often a starting point rather than an endpoint. Many neurodivergent adults find real value in ongoing support from a neurodivergent-affirming therapist, coach or counsellor, particularly around burnout, masking, identity, relationships and the day-to-day practicalities of executive function.
Neurodivergent-affirming coaching in particular has grown as its own discipline, often focusing on practical strategies for planning, task initiation and overwhelm, delivered by practitioners who bring their own lived experience of ADHD, being Autistic, or both, to the work. Therapy and counselling, meanwhile, often support the emotional processing that can come with a late identification, including grief for years spent without understanding, and the ongoing work of unmasking in a world not always built to accommodate that.
Dyslexic and dyspraxic adults face their own, often distinct, set of challenges, from processing written information to coordination and organisation. These experiences can also co-occur with ADHD and being Autistic, adding further layers to an individual's overall picture. Study support, workplace coaching and practical strategy work are often just as valuable here as formal assessment, particularly for adults who were never identified as dyslexic or dyspraxic in childhood and have spent years developing their own, sometimes exhausting, workarounds.
Many dyslexic adults describe reaching adulthood having built elaborate, often unconscious, systems to compensate for reading and processing difficulties, sometimes without ever realising these workarounds pointed to something identifiable. A formal assessment can validate what someone has long suspected about themselves, while practical support such as assistive technology, extra processing time, or workplace adjustments can genuinely reduce day-to-day friction, regardless of whether a person pursues formal identification at all.
Alongside ADHD and being Autistic, many neurodivergent people also live with OCD, PTSD or complex PTSD, or Tourette's, each with its own support needs. People with OCD often benefit from specialist, evidence-based therapeutic approaches, while people with PTSD or complex PTSD may need trauma-informed practitioners who understand how earlier experiences continue to shape present-day responses. People with Tourette's frequently describe wanting practitioners who understand tics as a neurological experience rather than something to be suppressed or apologised for. Finding a practitioner who genuinely understands these experiences, rather than treating them as a footnote to ADHD or autism, makes a meaningful difference.
Neurodivergent Practitioners was built specifically to close the gap between neurodivergent people and practitioners who understand their experience from the inside. The directory lists over a thousand practitioners across more than twenty countries, covering therapy, coaching, counselling, diagnostic services and peer support groups.
Every listed practitioner publicly commits to the directory's shared commitments to neuroaffirming practice, and many carry a verification badge confirming their professional registration or insurance was current at the time of checking. For anyone tired of explaining their neurodivergence from scratch to yet another professional, starting a search here, rather than with a generic directory, can make a genuine difference to how supported the process feels from the very first enquiry.
The written report that follows an assessment matters just as much as the assessment itself, since it often becomes the document a person carries into workplaces, universities and healthcare settings for years afterwards. A good, affirming report describes a person's actual experience and support needs in plain, respectful language, rather than relying heavily on deficit-based clinical shorthand.
There are times when a report written for an insurer, an employer or a public health service needs to use more formal, clinical language to do its job. Where that is necessary, a good practitioner explains this openly, so the person understands why certain language appears in the report without ever being left wondering whether that is how their practitioner truly sees them.
A good report also focuses on what actually helps, rather than stopping at a list of difficulties. This might mean specific, practical recommendations for a workplace, a university, or a GP, written in a way that the person receiving the report, whether that is the individual themselves or someone supporting them, can act on immediately. A report that only diagnoses without offering any practical direction leaves the hardest part of the work, working out what to actually do next, entirely to the person who has just received potentially life-changing news.
A little preparation can make an assessment appointment considerably less overwhelming. It often helps to write down specific examples of how ADHD or Autistic traits show up in daily life, rather than relying on memory in the moment, since assessments can move quickly and cover a great deal of ground.
Thinking back to childhood, even as an adult, can also be useful, since both ADHD and autism are understood as lifelong rather than newly appearing in adulthood. Old school reports, conversations with family members, or simply reflecting on patterns that go back as far as you can remember can all provide useful material. It is also entirely reasonable to prepare questions in advance, covering what happens after the assessment, how the outcome will be communicated, and what support, if any, follows a diagnosis.
Sensory needs are worth thinking about too. If fluorescent lighting, background noise, or unfamiliar environments make it harder for you to communicate clearly, it is reasonable to ask an assessor in advance whether the appointment space can be adjusted, or whether a video call might work better than an in-person visit. Many neuroaffirming practitioners will happily accommodate this, and asking does not reflect poorly on you or your assessment in any way. It is simply part of getting a fair, accurate picture of how you present when you are not fighting an uncomfortable environment on top of everything else.
Bringing a trusted person, whether a partner, parent, sibling or close friend, can also help, both for emotional support and because they may remember details from childhood or notice patterns in your day-to-day life that are hard to see clearly from the inside. Not every assessment allows for a support person to be present throughout, so it is worth checking this with the provider beforehand.
Is self-identification as Autistic or ADHD valid without a formal diagnosis?
Yes. Many neurodivergent people identify without ever pursuing formal diagnosis, often due to cost, waiting times, or past experiences of not being believed. Self-identification is increasingly recognised as a legitimate part of the neurodivergent experience.
What does "neuroaffirming" mean in practice?
It means understanding neurodivergence as a natural form of human variation rather than a disorder to be fixed, while still taking real difficulty seriously and offering genuine support rather than dismissing struggles as purely a product of an unaccommodating world.
How long does an NHS ADHD or autism assessment take?
Waiting times vary considerably, but many people wait several months to over a year for an NHS assessment, depending on local demand and the specific service involved.
Can ADHD and being Autistic occur together?
Yes. This is often described informally as AuDHD, and a thorough assessment should consider both possibilities together rather than assuming a single explanation for someone's experience.
Why does an assessor's training matter if lived experience is also important?
Because lived experience and clinical training serve different, complementary purposes. Structured, current training helps ensure an assessment is thorough and grounded in up-to-date evidence, while lived experience shapes how that assessment is delivered with genuine understanding.
How can I find a neurodivergent-affirming therapist, coach or assessor?
Neurodivergent Practitioners is a global directory specifically built around this need, listing practitioners across therapy, coaching, counselling, diagnostic services and peer support who publicly commit to neuroaffirming principles.
Do I need a diagnosis to get support at work?
Not always. Many workplaces will consider support and adjustments based on disclosed needs even without formal diagnosis, though a diagnosis can strengthen legal protections and access to certain forms of support in some contexts.
What should I do if I disagree with my assessment outcome?
You are entitled to ask questions about how the outcome was reached, and in many cases to seek a second opinion from a different practitioner if the result does not feel right to you.
What is neurodivergent burnout?
Neurodivergent burnout is a state of deep exhaustion and reduced capacity that can follow prolonged masking or sustained effort to function in an unaccommodating environment. Recovery often involves reducing masking and building in genuine accommodations, rather than rest alone.
Do assessors need lived experience of neurodivergence to be good at their job?
Not necessarily, though many people find working with a practitioner who has lived experience easier and more validating. What matters most is that an assessor combines rigorous, current clinical training with genuine respect for how the person being assessed understands themselves.
Finding the right support, whether that is a formal assessment, ongoing therapy, coaching, or simply a community that understands, should never feel like starting from zero each time. Directories built specifically for and by neurodivergent people, such as Neurodivergent Practitioners, exist to make that search easier, connecting people with practitioners whose lived experience genuinely informs how they work.
Behind the scenes, the quality of any clinical assessment also depends on the training of the professionals carrying it out, an area where organisations such as Global ADHD Network contribute by keeping healthcare professionals current with structured, evidence-based ADHD assessment practice. Lived experience and clinical rigour are not in tension with one another. Together, they are what make an assessment, or any form of neurodivergent support, genuinely affirming rather than simply a box-ticking exercise.
Wherever you are in this process, whether just beginning to wonder if ADHD or being Autistic explains a lifetime of experiences, or years into life with a diagnosis and looking for the right ongoing support, you deserve practitioners who meet you with curiosity rather than judgement, and a process that leaves you feeling more understood at the end than you did at the start.
