You've done the research. You've gone down the Reddit rabbit holes, watched the TikToks, taken the quizzes, and thought that's literally me more times than you can count. And yet you still don't have a clear answer.
If you've been wondering whether you might have both Autism and ADHD, you're in good company. A lot of people carry both — and a lot of those same people spent years being told they had one, the other, or neither.
This article breaks down what AuDHD actually is, what it tends to look like, and how a free quiz can be a useful first step toward finally getting some real answers.
What Is AuDHD?
AuDHD is the informal term for having both Autism Spectrum Disorder and ADHD at the same time. It's not a separate diagnosis on its own, but it is a genuinely distinct experience that deserves its own understanding.
Research suggests that somewhere between 50% and 70% of autistic people also meet the criteria for ADHD, and vice versa. These two neurotypes overlap in meaningful ways — but they also push against each other in ways that can make everyday life feel particularly disorienting.
For a long time, clinicians couldn't officially diagnose both at once. That changed with the DSM-5 in 2013, which removed the rule blocking a co-diagnosis. Since then, awareness of AuDHD has grown significantly, especially among adult communities who are finally seeing their experiences reflected back at them.
Why AuDHD Is So Often Missed
If you've gone years without a diagnosis, there are real clinical reasons for that. Not personal failings. Not you being dramatic or oversensitive.
ADHD and Autism can actually mask each other. Rigid routines and intense focus — common autistic traits — can look like someone managing their ADHD really well. Impulsivity and social misfires — common ADHD traits — can be mistaken for autistic social differences. When both are present at once, the picture gets complicated fast.
High-masking individuals, particularly women and BIPOC adults, are even more likely to be overlooked. Masking — suppressing or camouflaging neurodivergent traits to fit in — can make both ADHD and Autism nearly invisible in a standard clinical interview. A provider who isn't specifically trained to look for it may see a composed, articulate person and conclude there's nothing worth evaluating.
There's also the issue of how diagnostic tools were built. Many were developed on white male populations and simply weren't designed to catch how AuDHD presents in women, in people of color, or in adults who've spent decades quietly adapting.
The result is a lot of late diagnoses, a lot of misdiagnoses — anxiety and depression are common stand-ins — and a lot of people who know something is different but can't get anyone to confirm it.
Take the Free AuDHD Self-Assessment Quiz
The AuDHD test at Sachs Center is a free, clinician-designed self-assessment that screens for traits associated with both Autism and ADHD together.
It takes about two minutes. It's not a diagnosis. But it's a genuinely useful way to organize what you've been experiencing and get a clearer sense of whether a formal evaluation might be the right next step.
The quiz was designed by licensed psychologists who specialize in AuDHD — which means it's built to account for how these two neurotypes interact, not just how they each look in isolation.
After you finish, you'll have a better picture of where your traits land and what that might mean. From there, you can decide whether moving forward with a full evaluation makes sense for you.
Common Signs of AuDHD in Adults
AuDHD doesn't look the same in every person. But certain patterns come up again and again.
Attention and focus:
- Deep hyperfocus on specific interests, but near-impossible to engage with anything that doesn't hold your attention
- Starting many projects and finishing few
- Losing track of time easily — in both directions
Social experience:
- Feeling drained after social interactions, even ones you genuinely enjoyed
- Mentally scripting conversations before they happen
- Struggling to read unspoken social rules, then working overtime to hide that struggle
Sensory and emotional:
- Strong reactions to sensory input — sounds, textures, lighting
- Emotional responses that feel intense or disproportionate to people around you
- Rejection Sensitive Dysphoria (RSD): the sharp, overwhelming pain of perceived rejection or criticism
Daily functioning:
- Difficulty with transitions and unexpected changes to plans
- Executive function challenges that don't respond to standard ADHD strategies
- A persistent sense that you're always performing, always translating yourself for other people
If several of these feel familiar, that's worth paying attention to. If emotional rejection sensitivity is something you're trying to understand better, the free RSD self-assessment is also available.
How AuDHD Differs From ADHD Alone or Autism Alone
This is where things get genuinely interesting — and genuinely complicated.
ADHD on its own typically involves executive dysfunction, impulsivity, and attention dysregulation. Autism on its own typically involves differences in social communication, sensory processing, and a strong preference for routine and predictability.
When both are present, they interact in ways that can be hard to untangle. ADHD's impulsivity can clash directly with Autism's need for sameness. The hyperfocus that ADHD brings can look a lot like an autistic special interest. The social scripting that many autistic people rely on to navigate interactions requires exactly the kind of sustained mental effort that ADHD makes exhausting.
The result is often someone who doesn't fit neatly into either category. They may not "look autistic" to a clinician expecting stereotyped presentations. They may not "look ADHD" to someone expecting constant, visible hyperactivity. They fall through the gaps — sometimes for decades.
That's exactly why a co-evaluation — one that assesses for both ADHD and Autism at the same time — is so much more useful than testing for one and assuming the other isn't there.
What Happens After the Quiz?
The free quiz gives you a starting point. It's not a clinical diagnosis, and it can't replace one. But it can help you figure out whether taking the next step makes sense.
If your results suggest traits consistent with AuDHD, the logical move is a formal evaluation with a licensed psychologist who understands how both neurotypes present together — and who knows what masking actually looks like in practice.
At Sachs Center, evaluations are done entirely via telehealth, available across 48 or more states through PSYPACT interstate authority. No 18-month waitlist for an in-person appointment. No traveling to a specialist. No sitting in a waiting room under fluorescent lights trying to hold it together.
The evaluation itself is comprehensive — not a quick questionnaire or a 20-minute intake. It's a full neuropsychological assessment designed to capture how you actually function, including the parts you've learned to hide.
Why a Formal AuDHD Evaluation Matters
You might be wondering whether the quiz is enough. Whether you can just use the results to advocate for yourself without going any further.
That's a fair question, and the honest answer is: the quiz is a useful tool, but it has real limits.
A formal evaluation gives you documented clinical findings. That documentation matters when you're requesting workplace accommodations or academic accommodations. It matters for extended time on standardized exams like the SAT, GRE, or GMAT. It matters when you're talking to a prescriber about medication. It matters when you want to understand yourself at a level that goes beyond a screening tool.
And beyond the practical uses, a formal evaluation done by psychologists who specialize in AuDHD gives you something harder to put a number on: clarity. A lot of people describe their diagnosis as the first time their whole life made sense. That's not a small thing.
If you've spent years wondering, masking, compensating, and being told you're fine — you deserve an actual answer.
FAQs
What is an AuDHD test?
An AuDHD test is a screening tool or formal evaluation that assesses whether someone has traits consistent with both Autism and ADHD occurring together. Free self-assessment quizzes can be a useful first step, but only a licensed psychologist can provide a clinical diagnosis.
Can you have both Autism and ADHD at the same time?
Yes. Research consistently shows that a large percentage of autistic people also have ADHD, and vice versa. Since the DSM-5 was updated in 2013, clinicians have been able to formally diagnose both at the same time.
Why do so many people with AuDHD go undiagnosed?
ADHD and Autism can mask each other, making both harder to detect. High-masking individuals — particularly women and BIPOC adults — are especially likely to be missed, because many standard diagnostic tools weren't developed with their presentations in mind.
Is the free AuDHD quiz a real diagnosis?
No. The free quiz is a clinician-designed screening tool that can help you identify whether a formal evaluation might be worth pursuing. It is not a clinical diagnosis and shouldn't be used as one.
What does a formal AuDHD evaluation involve?
A comprehensive AuDHD evaluation with a licensed psychologist typically includes structured clinical interviews, standardized testing, behavioral rating scales, and a review of your personal and developmental history. The goal is a full picture of how you function — not just a snapshot.
How is AuDHD testing done via telehealth?
Telehealth AuDHD evaluations are conducted through secure video platforms. Licensed psychologists administer standardized assessments remotely and review the results with you in a follow-up session. Sachs Center offers this service across 48 or more states through PSYPACT licensure.
What can I do with an AuDHD diagnosis?
A formal diagnosis opens real doors. It can support requests for workplace accommodations, academic accommodations, extended time on standardized exams, and access to targeted therapy or coaching. Many people also describe the diagnosis itself as deeply clarifying — finally giving context to experiences they couldn't previously explain.
You've been asking the right questions. The quiz is a good place to start. If it points toward something worth exploring further, a full evaluation is available from home, on your schedule, with clinicians who actually know what AuDHD looks like.
