AuDHD, Honestly: A Guide for Adults with Autism and ADHD

AuDHD means being autistic and having ADHD at the same time. The word joins the two, Au for autism and DHD for ADHD. It was made by the community, not by a diagnostic manual, and many people use it because neither label on its own describes how the two sides pull against each other.

Not as a single diagnosis. AuDHD is a community word. The diagnoses are autism and ADHD, and a clinician can diagnose both in the same person. What people describe under the word is real, and you don't need a formal diagnosis to use the tools in this book.

Yes. Since the DSM-5 in 2013, clinicians can diagnose both. For almost two decades before that, the manual many of them work from didn't allow ADHD to be diagnosed alongside autism, which is part of why so many adults found out late. Having both is common. In a review that pooled dozens of studies, about 28% of autistic people also had an ADHD diagnosis, and a guideline paper from one specialist autism clinic quotes estimates of 40 to 70%, depending on the study.

ADHD on its own and AuDHD share the ADHD side: trouble starting what isn't interesting, a pull toward novelty, feelings that hit fast. With AuDHD, an autistic side sits alongside it and often asks for the opposite: predictability, less input, time to recover. That clash is what adults with both describe most, and it's why advice written for ADHD alone often doesn't hold. The comparison on this page sets the differences side by side.

There's no official list of AuDHD symptoms, because AuDHD isn't a diagnosis on its own. What adults with both describe most is a push and pull: needing a routine and getting bored of it, seeking noise and then being overwhelmed by it, saying yes to plans and paying for it after. Many also describe one side hiding the other for years. Chapter 1 sorts these patterns into two columns and a middle.

There's no single AuDHD test. Autism and ADHD are each assessed by a qualified clinician, and one assessment can look at both. Online quizzes can't diagnose either. If you're wondering whether it's you, worksheet 1.1, the two-column pattern check, and worksheet 1.2, the hiding questions, help you put what you notice on paper and take real examples to an assessment. Both are free on this page.

This book is for adults of any gender, and most of what it covers applies to everyone. What often differs for women is how long it takes to be seen. In a study of 1,211 autistic adults, women reported earlier diagnoses of personality, anxiety and mood conditions, ones they now see as mistaken, more often than men did. And among children and teens diagnosed with ADHD first, autism was diagnosed later in girls than in boys, 2.6 years later against 1.5 on average. A rule-following girl who holds it together at school is easy to miss.

Rejection sensitive dysphoria, or RSD, is a community term for an intense, fast emotional reaction to rejection or criticism, real or perceived. It isn't a diagnosis, and the research on it is still thin, so you won't find a percentage for it here. What is well documented is that feelings come fast and land hard in adult ADHD. With AuDHD, people often describe rejection hitting twice: the sting in the moment, then a replay that runs that night. Chapter 6 has a tool for each part.

Executive dysfunction means trouble with the mental skills that plan a task, start it, keep it going, finish it and switch to the next. In ADHD it often shows as not being able to start what isn't interesting or urgent. Autistic people describe a related experience called inertia, where stopping can be as hard as starting, because stopping is a change too. With both, a task can stall in more places. Chapter 5 helps you find where yours stops, and Find Your Bottleneck goes further on the ADHD side.

A meltdown is overload coming out: crying, shouting, slamming a door, leaving the room. A shutdown is overload going in: going quiet, losing words, wanting to be left alone. Both are what an overloaded nervous system does, not a choice, and the same person can have both on different days. People with both often do. Chapter 7 covers your first signs and what each one needs, before and after.

It isn't a formal term, but adults with both often describe burnout that comes from two directions at once. The autistic side is worn down by input, people and masking. The ADHD side is worn down by years of pushing across the gap between wanting to and doing. The two need opposite fixes: a quiet week alone can help the first and starve the second. Chapter 12 helps you see it coming weeks ahead and sort which side is paying. There are free pages on autistic burnout and ADHD burnout too.

Some people with both describe exactly that. The ADHD is treated, focus improves, and the overload, the need for sameness or the tiredness after people stands out more than before. Others notice no change on the autistic side at all. Medication treats the ADHD, not the autism, so this doesn't mean it failed. It's worth tracking and raising with your prescriber. This book never tells you whether to start or stop anything.

Many adults describe it feeling harder as they get older, and some notice it most in the years around menopause. What they usually describe is less a change in the traits than in the cost of holding them down, as life fills up and the margin gets smaller. Many also notice more after a diagnosis, once they stop covering for it, and say it eases with time. If something is changing quickly, take it to a doctor.

No. Chapter 1 is built around the question most people start with: is it AuDHD, or just ADHD, or just autism? It helps you see the patterns and prepare for an assessment if you want one. Self-identification is respected throughout.

No. Start Here sends you one of three ways: the two-minute versions if today is a hard day, Part One if you're new to this, or straight to the chapter that's hardest for you right now.

No. Chapter 11 explains how the medication decision works for people with both, what people report, and what to ask, so you can walk into the appointment prepared. It contains no doses, no brand names and no advice to start or stop anything. That decision belongs to you and a prescriber who knows you.

Adults, of any age and any gender. If you're looking for help with a child, this isn't the right book.

The text is the same. The paperback has all 45 worksheets printed in, ready to write on. The Kindle edition has every worksheet in text form, and the printable versions are free on this page.

Yes. All 45 worksheets from the book are free on this page, as single PDFs or one 48-page kit, with no email sign-up. They're sized to print on A4 and US Letter.

Mark Chapters, who isn't a doctor or a researcher and says so. It's built from reader reviews of the other books on this shelf, accounts adults with both share in public, and 46 studies, reviews and guidelines. Every claim is marked by who it was studied in, and the book says plainly that no clinician has reviewed it.
