In short
AuDHD refers to having ADHD and autism at the same time – long considered a contradiction, now recognised as one of the most common combinations. The real issue isn’t the diagnosis, but the inner contradiction: one part of you needs structure and sameness, another craves stimulation and change.
Two systems, one body
AuDHD isn’t a diagnosis of its own but shorthand for something long thought impossible: autism and ADHD together. Until a few years ago, the leading diagnostic manual didn’t even allow both to be diagnosed in the same person. Today we know they overlap often – a substantial share of autistic people also show ADHD traits, and vice versa.
What defines AuDHD isn’t the sum of the traits but the friction between them. Put simply: the autistic part seeks predictability, sameness and clear rules. The ADHD part seeks novelty, pace and stimulation, and gets bored in exactly the place where the autistic part feels safe.
Why AuDHD was overlooked for so long
From the outside, the two profiles often cancel each other out. Someone carrying autistic love of order and ADHD impulsivity can appear surprisingly “average”, not because little is happening, but because two opposing forces partly balance out.
An example: the autistic part builds careful systems and routines. The ADHD part doesn’t stick to them. From the outside this looks like someone who “could do it if they just pulled themselves together.” From the inside it’s the wearing back-and-forth between creating order and losing it.
The inner contradiction in everyday life
The conflict shows up less in big moments than in a thousand small ones. Three typical areas of tension:
STRUCTURE
The autistic part needs the plan.
The ADHD part breaks it, and then comes the self-reproach for “not even keeping your own rules.”
STIMULATION
The ADHD part seeks stimulation to stay awake and present.
The autistic part is quickly flooded by that same stimulation. Too little input is tiring, too much is overwhelming, and the window between them is narrow.
CHANGE
The ADHD part wants variety and new projects.
The autistic part needs time for transitions and suffers under unannounced change. The longing for the new and the fear of change live in the same person.
This simultaneity is the real core of AuDHD. It isn’t “sometimes this, sometimes that” – it’s both at once, and the energy it takes to manage is almost never seen from the outside.
Why the two profiles mask each other
In assessment, AuDHD regularly leads to wrong conclusions. If the ADHD part stands out first, autistic sensory sensitivity gets read as a mere “concentration problem.” If the autistic part is in the foreground, ADHD restlessness gets dismissed as “anxiety” or “stress.”
Add to that masking: many AuDHD people learned early to cover up both sides. It costs enormous energy and often means that in the end neither profile is clearly visible, only the exhaustion.
Important: An assessment that looks for only one profile will almost inevitably miss AuDHD. If you recognise yourself in both, there’s usually a good reason.
What actually helps with AuDHD
The most useful shift in perspective: it’s not about finding the “right” one of the two parts and training the other away. Both are real. It’s about doing justice to each in turn.
In practice that often means flexible structures instead of rigid plans – routines that give enough hold but allow deviation without everything collapsing. And dosing stimulation rather than avoiding it or chasing it: consciously steering when stimulation helps and when retreat is needed.
Perhaps most important is self-compassion for the contradiction. Anyone who has spent years condemning themselves as “inconsistent” can learn that this inconsistency is an understandable response to two opposing needs.
“AuDHD isn’t a contradiction to be resolved – it’s a balance that wants to be found again and again.”

If this sounds familiar
If you swing back and forth between needing structure and being tired of it, wondering whether both can be true at once: you don’t have to sort this out alone.
Coaching can be a space to understand your two parts better and find a day-to-day life that does justice to both, without turning against yourself.
