This is lived experience and general information, not medical advice. If you think you might be autistic, ADHD or both, an assessment with a qualified clinician is the way to know.
ADHD is about attention, activity and impulse regulation: the brain hunts for stimulation, struggles to start boring tasks, can hyperfocus on interesting ones, and runs on a clock of its own. Autism is about how you process the world, especially social communication and sensory input: predictability feels safe, surprises cost a lot, and senses can be turned way up (or down).
AuDHD is the community’s word for having both. It isn’t a separate condition; it’s what it’s like when the two live in one head.
Why AuDHD can feel like a tug of war
The two can want opposite things. The autistic side wants routine; the ADHD side gets bored of every routine within a week. The autistic side needs quiet; the ADHD side goes looking for stimulation. Hence the most AuDHD sentence we know: “I need routine. I hate routine.”
The two can also mask each other. ADHD restlessness can hide autistic shutdown; autistic rule-following can cover for ADHD chaos. That’s one reason many people, especially women and adults, are recognised late, or get one diagnosis long before the other.
ADHD alone vs AuDHD, in everyday life
- Change: ADHD alone often enjoys novelty. AuDHD tends to crave novelty and be thrown by unexpected change at the same time.
- Social energy: both can find socialising tiring, but AuDHD often adds the work of decoding unwritten rules, and a social battery that empties fast.
- Sensory stuff: sensory sensitivity shows up with ADHD too, but it’s central to autism: tags, seams, noise and lights can be genuinely painful.
- Focus: ADHD hyperfocus jumps between interests; autistic special interests tend to be deep and long-lasting. AuDHD can have both, sometimes about the same thing.
Why we named the shop after it
Because it’s our house. And because finding the word AuDHD is a real moment for a lot of people: the first time two lists that never quite fit finally describe you together. Our AuDHD collection is for that moment.
Quick answers
Is AuDHD a diagnosis?
Not as one word. AuDHD is community shorthand for having both an autism diagnosis and an ADHD diagnosis (or recognising both in yourself). Clinicians diagnose the two separately.
Can you be diagnosed with both autism and ADHD?
Yes. Older diagnostic rules said ADHD shouldn’t be diagnosed alongside autism; the DSM-5 changed that in 2013, so both can now be diagnosed together.
How common is it?
Very. Estimates vary a lot between studies, but a large share of autistic people (often reported as somewhere between a third and more than half) also have ADHD.
Where do I start in Canada?
Your family doctor or nurse practitioner is usually the first step to an assessment referral. CADDAC (caddac.ca) has ADHD resources for Canadians, and your provincial autism society can point you to adult autism assessment options near you.
