Three readings rather than one score: how much you recognised on each side, how much you recognised in the questions where the two contradict, and separately whether this goes back to childhood. There is no total, because a total hides the contradiction you came here to check.

What does AuDHD stand for?

AuDHD stands for Autism and ADHD together in the same person. It is a blend of "Au", the chemical symbol style abbreviation the autistic community adopted for autism, and "DHD" from ADHD, which itself stands for Attention Deficit Hyperactivity Disorder. Written out in full, AuDHD means autistic and ADHD, or autism spectrum disorder co-occurring with attention deficit hyperactivity disorder.

It is worth being clear that AuDHD is a community term, not a diagnostic one. You will not find it in the DSM-5 or the ICD-11. What you will find there, since 2013, is permission to diagnose autism and ADHD in the same person, which the previous edition of the DSM did not allow. That single rule change is why so many adults were given one label in childhood and the other decades later, and why the word AuDHD had to be invented by the people living it rather than handed down by clinicians.

What is AuDHD, in practice?

In practice AuDHD is a set of arguments your own brain has with itself. You need things to stay the same, and you are bored out of your mind when they do. You plan carefully and then abandon the plan. You want company badly and come home from it hollowed out. You can hold attention on one subject for nine hours and cannot start a two minute task.

Each half of that is unremarkable on its own. An autistic person who needs routine makes sense. Someone with ADHD who chases novelty makes sense. The person who does both, in the same week, about the same thing, does not fit either description, which is why so many people spend years reading about autism, deciding it is nearly right, reading about ADHD, deciding that is nearly right too, and concluding they must be making it up. They are usually not making it up.

AuDHD vs ADHD: how to tell which you are reading about

The AuDHD vs ADHD question is the one people get stuck on, and the honest answer is that the surface behaviour often looks identical while the reason underneath is different. Someone with ADHD alone and someone with AuDHD can both miss a deadline, both interrupt, both lose the thread of a conversation. What separates them is usually not the behaviour but what happens around it.

A few of the differences that tend to hold up. Sensory load: ADHD alone does not usually mean a particular fabric is unbearable or a supermarket is physically exhausting. Routine: ADHD tends to find routine boring, while AuDHD finds an unchosen change genuinely distressing and still finds its own routine boring. Social difficulty: ADHD social trouble often comes from impulsivity and missing the moment, where AuDHD social trouble includes having to work out the rules deliberately and then run them manually. Recovery: the flat, wordless exhaustion after a long social day is far more an autistic pattern than an ADHD one.

The other half of AuDHD vs ADHD is what happens when you treat one and ignore the other. People whose ADHD is recognised and whose autism is not often describe stimulant medication as helpful and insufficient: the attention improves and the sensory exhaustion, the masking and the need for recovery time do not move at all. That mismatch is frequently the thing that eventually sends somebody looking for the second half of the picture.

Why this free AuDHD test is more careful than most

There are a lot of AuDHD quizzes online and most of them share the same four problems. This one was built specifically to avoid them, and it is worth saying how, because "we are more accurate" means nothing without a reason attached.

The questions are mixed, not grouped. Most tests put all the sensory questions together, then all the social ones. The moment you notice the grouping you start answering the category rather than the question, and your answers drift to match the story you have just worked out about yourself. Here the thirty scored items are interleaved so that no two neighbouring questions come from the same area, and no area name appears anywhere during the test.

Six items are reverse-keyed. On those, agreeing indicates less of a trait, not more. This is the standard defence against acquiescence bias, the well documented tendency to agree with whatever a questionnaire puts in front of you. It also means that answering everything the same way produces a result the test can detect and flag, rather than a middling score that looks meaningful and is not.

Nothing is added into one total. Autism-leaning items, ADHD-leaning items and the conflict items are reported separately. A single score would let you aim at it, and more importantly it would hide the one thing you came here to find out, which is whether both patterns are present at once.

When it started is scored on its own axis. Burnout, long stress, depression, chronic pain and a bad year all produce a great deal of what this questionnaire asks about. Every test that ignores onset and context will hand those people a high score and let them walk away believing something that is probably not true. Six questions here ask only about childhood and about whether the pattern shows up in more than one setting, and they are reported separately so you can see the difference.

That is the case for calling this one of the more thorough free AuDHD tests available online. It is still a questionnaire. It cannot examine you, it has no access to your history, and it has never been validated against clinical diagnosis, because no free online instrument has.

AuDHD in women and girls

Both autism and ADHD were described, researched and diagnosed for decades using samples that were mostly boys, and the diagnostic pictures that came out of that work still carry the shape of those samples. The practical consequence is that a great many women reach their thirties and forties with no diagnosis of either condition and a long list of things that were said about them instead: anxious, sensitive, dramatic, lazy, too much, not applying herself.

Masking is a large part of why. Girls are more often taught, early and relentlessly, to watch what other people do and copy it. The result can be someone who maintains eye contact, holds a conversation, has friends and appears to be coping, while running a conscious simulation of all of it and paying for the day afterwards in a dark room. None of that is visible to an observer, which is precisely the problem with diagnostic criteria built around what an observer can see.

If this is the part you came for, the CAT-Q test on this site is the one that looks specifically at camouflaging, and is worth taking alongside this AuDHD test.

What are the signs of AuDHD?

There is no official list, since AuDHD is not an official diagnosis. What follows is the pattern that comes up repeatedly in accounts from people with both diagnoses, and it is the pattern this questionnaire is built around.

  • Needing structure in order to function, and being unable to hold a structure you set yourself.
  • Intense focus available for some things and completely unavailable for others, with very little say in which is which.
  • Sensory sensitivity that fluctuates, so the same noise is fine on Tuesday and intolerable on Thursday.
  • Wanting social contact and being drained by it, often both in the same evening.
  • Rehearsing conversations in advance and replaying them afterwards.
  • Emotions that arrive at full volume and take a long time to settle.
  • A pile of unfinished projects that were each, at the time, the most important thing in the world.
  • Exhaustion that does not match what you actually did that day.

What else produces this pattern

This matters more than the score, so it is here rather than buried at the bottom. A high result on any AuDHD test is also consistent with several other things, and an honest result page has to say so.

Autistic burnout and ordinary occupational burnout both flatten executive function, raise sensory sensitivity and shrink social tolerance. Depression does much of the same. Untreated ADHD on its own produces emotional intensity and social difficulty that can read as autistic. Anxiety produces rehearsal and replay that look exactly like masking. Long-term sleep deprivation, which is extremely common in both populations, produces most of the attention items by itself. Trauma produces hypervigilance that is easily mistaken for sensory sensitivity.

The question that separates these is not how much, it is since when. That is the entire reason the six context questions exist and are scored on their own axis.

What to do with your result

If the pattern looks longstanding and shows up in more than one part of your life, the useful next step is not another questionnaire. It is writing down three or four concrete examples from different periods of your life, ideally including childhood, because that is the material an assessor actually works from. A screenshot of a score is not.

If the pattern looks recent, the first thing worth ruling out is whatever has been happening for the past year or two. That is not a dismissal. It is the order a competent clinician would work in, and doing it yourself saves time.

Either way, take it to a GP or a qualified assessor rather than to a forum. This free AuDHD test can tell you whether a conversation is worth having. It cannot have the conversation for you.

Other tests worth taking alongside this AuDHD test

If you came here through the AuDHD question, several of the other screeners on this site look at one side of it in more depth:

AuDHD test questions people actually ask

What is AuDHD?

AuDHD is the term for being autistic and having ADHD at the same time, and it describes a pattern that is not simply the two conditions added together. The two sets of traits frequently pull in opposite directions, so the same person can need predictable routine and be unable to tolerate it, or crave company and be drained by it, which is why descriptions of autism alone or ADHD alone so often feel almost but not quite right.

What does AuDHD stand for?

AuDHD stands for autism and ADHD occurring together in the same person, combining "Au" for autism with the "DHD" of Attention Deficit Hyperactivity Disorder. It is a community term rather than a clinical one, so it does not appear in the DSM-5 or ICD-11, although both manuals have allowed autism and ADHD to be diagnosed in the same person since 2013, which earlier editions did not.

Is this AuDHD test free?

Yes, this AuDHD test is completely free, with no account, no email address, no payment and no paywalled result at the end. Your answers are scored in your own browser and are not sent anywhere, so you can close the page at any point and nothing is kept except a local note that lets you pick up where you left off on the same device.

Why is this AuDHD test better than most online AuDHD tests?

This free AuDHD test avoids the four things that make most online versions unreliable, which is the only reason it is worth calling it more careful. It interleaves the questions so you cannot see which area you are answering, reverse-keys six items to catch agreement bias, reports the autism-leaning and ADHD-leaning answers separately rather than as one total, and scores when the pattern started on its own axis so that burnout and depression are not quietly counted as autistic or ADHD traits.

Is AuDHD a real thing?

The co-occurrence is real and well documented, even though the word AuDHD itself is community shorthand rather than a diagnostic label. Before 2013 the DSM explicitly forbade diagnosing autism and ADHD in the same person, so a large number of adults were given one label and never assessed for the other, and the research since that rule changed has consistently found the two conditions overlapping far more often than chance would predict.

What does AuDHD look like in girls?

In girls it very often looks like a child who is coping, because the social copying starts early and hides most of what the diagnostic criteria were written to spot. The visible signs tend to be indirect: exhaustion after school that nobody can account for, intense but socially acceptable interests, friendships that are managed with conscious effort, and emotional reactions at home that look disproportionate to anyone who did not see the day she just had.

Is AuDHD in women common?

It appears to be considerably more common than diagnosis rates suggest, because both conditions were characterised using mostly male samples and the resulting criteria describe how they present in boys. The practical result is a large group of women who reach adulthood with neither diagnosis, often carrying anxiety or depression labels instead, and who only encounter the AuDHD description after a child, a sibling or a friend is assessed.

What is the best treatment for AuDHD?

There is no single treatment, because AuDHD is not a single condition and the two halves respond to different things. In practice most approaches combine whatever helps the ADHD side, which may include medication, with accommodations for the autistic side such as sensory management, predictable structure and genuine recovery time, and a qualified clinician is the only person who can judge the balance for you.

What is it like having AuDHD?

The most common description is of being pulled in two directions at once by your own brain, wanting structure and sabotaging it, seeking stimulation and being overwhelmed by it. People frequently describe a specific kind of frustration that comes from knowing exactly what they need and being unable to supply it consistently, along with tiredness that does not match the day they actually had.

What are the signs of AuDHD?

The recurring signs are contradictory ones: needing routine and breaking it, deep focus on some things alongside complete inability to start others, sensory sensitivity that fluctuates day to day, and wanting company while being drained by it. Alongside those sit rehearsing conversations before and replaying them after, emotions that arrive at full volume, a long trail of abandoned projects, and exhaustion out of proportion to what was done.

At what age is ADHD noticeable in girls?

Signs are often present from primary school age, but they are noticed far later in girls than in boys, frequently not until secondary school, university or adulthood. The usual reason is presentation: inattentive ADHD without visible hyperactivity reads as daydreaming, disorganisation or anxiety rather than as a disorder, and a child who is quiet and not disrupting the classroom rarely gets referred for assessment at all.

Do ADHD meds work for AuDHD?

Stimulant medication often helps the ADHD side of AuDHD, and many people report real improvement in attention and task initiation, but it does not touch the autistic side. A very common experience is that medication makes the attention problems manageable while the sensory load, the masking and the need for recovery time stay exactly where they were, which is frequently what prompts someone to go looking for the other half of the picture.

Is ADHD linked to higher IQ?

No, ADHD is not linked to higher IQ, and the research does not support the popular claim that it is. What is true is that ADHD and measured intelligence are largely independent, so bright people with ADHD are common and are often diagnosed late precisely because their ability masked the difficulty for years until the demands of work or university finally outran the compensation.

Can autistic kids be very social?

Yes, and the assumption that they cannot is one of the main reasons autistic children are missed, particularly girls. Plenty of autistic children actively want friendship and seek it out energetically, and the difficulty is not in the wanting but in the mechanics: reading unspoken rules, keeping up reciprocal conversation, and managing the exhaustion that follows, which is often invisible until they get home.

What is the difference between AuDHD vs ADHD?

The AuDHD vs ADHD distinction is rarely about the visible behaviour, which often looks the same, and usually about what surrounds it. ADHD alone does not typically bring sensory sensitivity, distress at unchosen change, deliberate rule-working in social situations, or the flat wordless exhaustion after a long social day, and the presence of those alongside the attention difficulties is what moves the picture toward AuDHD.

Can you be diagnosed with both autism and ADHD?

Yes, since 2013 both major diagnostic manuals permit autism and ADHD to be diagnosed in the same person, which was explicitly prohibited under the previous edition of the DSM. That change is why so many adults hold a childhood diagnosis of one and receive the other decades later, and why assessment services are still catching up with a backlog of people who were only ever screened for half of it.

How long does this AuDHD test take?

Most people finish this AuDHD test in about seven minutes, covering thirty scored statements and six questions about when and where the pattern shows up. There is no timer and no benefit to rushing, although first reactions tend to be more accurate than carefully reasoned ones, and your progress is saved in your own browser if you need to stop and come back.

Does a high score mean I have AuDHD?

No, a high score means your answers match the pattern this questionnaire describes, which is a reason to look further rather than a conclusion. Burnout, depression, long-term stress, chronic sleep deprivation and anxiety all produce a great deal of the same thing, which is exactly why the result reports separately on whether the pattern looks lifelong or recent, and why only a qualified assessor can settle it.
