Understanding AuDHD
AuDHD is complex, not contradictory. Learn what it is, the common signs, why it’s often missed, and when an assessment might help.
What is AuDHD?
‘AuDHD’ isn’t a clinical term – it’s the name people often use for having both ADHD and autism. The two are diagnosed separately, but many people have both. It can feel like your brain is pulling you in opposite directions, with needs that seem to compete.
It's complicated
ADHD and autism traits can amplify, alter and cancel each other out.
It affects concentration
Focus can drift, then lock onto one interest for a long time.
It influences daily life
People might crave sameness one moment, novelty the next.
It can be assessed
Autism and ADHD can be diagnosed with a joint (dual) assessment.
Signs of AuDHD
It's rarely just autism traits and ADHD traits side by side – the two conditions interact. That interaction looks different for everyone, which is exactly why AuDHD can be hard to recognise.
When they pull apart
Having AuDHD means living with both ADHD and autism – two sets of needs that don’t always agree with each other. This can show up as:
- Wanting routine, but getting bored by it
- Craving connection, but finding socialising exhausting
- Needing structure, but struggling to start or stick to it
When they pull together
ADHD and autism traits can sometimes reinforce each other, making things feel even more intense. This can feel like:
- Masking social differences and impulsivity at the same time
- Sensory overwhelm making emotions or attention harder
- Intense focus on one interest, and difficulty switching tasks
AuDHD is unique. No two people are the same
How AuDHD shows up depends on which traits are more dominant, your age, gender and life stage.
AuDHD in children
A child with AuDHD might be labelled 'difficult' or 'daydreamy', without anyone realising both conditions are at play.
AuDHD in children and young people can look like:
- Strong reactions to sensory input and constant fidgeting
- Meltdowns that build from both overwhelm and impulsivity
- Intense focus on one interest – struggling to sit still for anything else
AuDHD in adults
Traits can mask each other, so people often spend years being treated for one condition – but not the other.
AuDHD in adults can look like:
- Switching between hyperfocus and losing all motivation
- Wanting routine, then struggling once it's in place
- Alternating between overstimulation and understimulation
AuDHD in students
University can be uniquely hard with AuDHD – craving freedom, but struggling without the structure that helped mask things before.
AuDHD in students can look like:
- Sensory overload in lecture halls, alongside difficulty focusing
- Procrastination followed by intense hyperfocus
- Feeling isolated and needing more downtime than peers seem to
AuDHD in women
Masking gets more complex with AuDHD – many girls and women learn to hide both the social effort of autism and the impulsivity of ADHD.
AuDHD in women can look like:
- Appearing organised on the outside while struggling internally
- Social exhaustion combined with restlessness
- Cycles of hyperfocus and burnout
AuDHD in later life
For older adults, an AuDHD diagnosis can explain a lifetime of feeling both under-stimulated and overwhelmed.
AuDHD in later life can look like:
- Decades of burnout from masking two sets of traits at once
- Needing more downtime after sensory and mental overload
- Routines that help, but also feel restrictive
Why AuDHD is so easy to miss
One masks the other
ADHD impulsivity can hide autism’s need for routine - and vice versa.
Complex traits
Wanting structure and craving novelty can look inconsistent.
Masking gets doubled
Many mask both traits – especially women, girls and marginalised genders.
One joint assessment
Unlike most providers, we can assess autism and ADHD together.
Real stories
To understand what it’s like to be diagnosed autistic and ADHD, there’s only one bunch of people to ask: the people that live it every day.
'I struggle with being in unfamiliar situations and with unfamiliar people. However my assessor was very patient with me, very kind and very thorough. From the moment she started speaking I felt calm by her voice. She was also very skilled and could separate my autism symptoms from symptoms that would indicate ADHD.'
'As an already diagnosed autistic who usually can't speak to strangers, my assessor made me feel very at ease and I found it very easy to talk to him which has surprised us all. He explained everything amazingly and when I didn't understand a question he was able to reword it so that I could.'

Your questions, answered
Is AuDHD a real diagnosis?
Not officially – 'AuDHD' isn't a clinical term. Autism and ADHD are diagnosed separately, but many people use 'AuDHD' to describe having both together.
Why do autism and ADHD often occur together?
Researchers don't fully know why, but the two conditions share some underlying traits and often run in the same families.
Is AuDHD hereditary?
Genetics plays a role in both autism and ADHD individually, and having a close family member with one condition can increase the likelihood of having either, or both.
Does having both conditions make things harder to manage?
Not necessarily harder, but different – the two conditions can conflict, so support usually needs to address both together rather than treating them separately.
