What Is AuDHD? ADHD and Autism Together in Adults
AuDHD means being both autistic and ADHD. Learn how the two overlap, why AuDHD adults are often missed, and how an evaluation can look at both.

The short answer: "AuDHD" is a word many people use when they are both autistic and have ADHD. It isn't a separate diagnosis. It means a person meets the criteria for both. The two often happen together, and each one can hide the other. That's why many AuDHD adults go years without the full picture.
How common is it?
More common than most people think. Until 2013, doctors weren't allowed to diagnose autism and ADHD in the same person. That changed with the DSM-5. Since then, research has found that a large share of autistic people also have ADHD, and many people with ADHD have autistic traits. Estimates vary from study to study, but the overlap is clearly large.
Why AuDHD is often missed
Autism and ADHD can pull in opposite directions. That can make each one harder to see.
- Routine vs. novelty. Autism often brings a need for routine and predictability. ADHD often brings a craving for new things and a hard time sticking to routines. Living with both can feel like a tug-of-war.
- Focus. Both can come with deep focus on interests. Both can make it hard to focus on things that don't hold your interest.
- Social life. Autism can make social rules confusing or tiring. ADHD can lead to interrupting or losing track of conversations. One may get blamed for the other.
- Masking. Many adults, especially women, learn to hide their traits to fit in. Masking takes a lot of energy and can lead to burnout.
Often, one diagnosis comes first. ADHD is usually found earlier. Autism may only come up later, when ADHD treatment helps but doesn't explain everything.
Signs you might be AuDHD
Everyone is different, but AuDHD adults often describe:
- Wanting structure, but struggling to keep it up
- Strong sensory reactions to noise, light, textures, or crowds
- Getting deeply absorbed in interests and losing track of time
- Feeling drained after social time, even when you enjoyed it
- Trouble starting tasks, even important ones
- Feeling like ADHD treatment helped some things, but not all
- Long stretches of burnout after periods of masking
Why the full picture matters
Knowing you're AuDHD can change what helps. For example, an ADHD plan that adds lots of new tools and systems may overwhelm someone who is also autistic. And autism supports that focus only on routine may not work for someone who also needs novelty. A plan that fits both is more likely to stick.
Many adults also tell us the answer itself helps. It can explain a lifetime of feeling "different" without knowing why.
How we evaluate AuDHD at Neurokin
We can look at ADHD and autism in one AuDHD evaluation, so you don't have to start over with two separate processes. We take a neurodiversity-affirming approach. Our goal is to understand how your brain works, not to "fix" who you are.
- We listen. We talk about your life now and growing up.
- We test. You complete rating scales and objective tests for attention, thinking, and autistic traits.
- We explain everything. You get your results, a diagnosis if one fits, and a written care plan.
