AuDHD: Understanding Autism and ADHD Together

You may have come across the term AuDHD while researching Autism Spectrum Disorder (ASD) or ADHD and wondered what it means.

Perhaps you've recognised characteristics of both Autism and ADHD in yourself or your child. You may relate strongly to information about autism, but also recognise difficulties associated with ADHD. Or perhaps you've received one diagnosis and are wondering whether the other might explain some of the experiences that don't quite fit.

AuDHD is an informal term used to describe the co-occurrence of autism and ADHD. It isn't a formal diagnostic term, but some people find it helpful because it reflects their experience of having characteristics of both conditions.

What does AuDHD mean?

AuDHD combines Autism and ADHD.

It is generally used when a person has Autism and also has ADHD. Spectrum Disorder and ADHD are both neurodevelopmental conditions, but they are different. Autism is associated with differences in social communication and interaction, as well as restricted or repetitive patterns of behaviour, interests or activities. ADHD is associated with persistent difficulties relating to attention and/or hyperactivity and impulsivity.

They can occur together.

For some people, understanding the overlap between the two can help make sense of experiences that may otherwise seem contradictory.

For example, someone might strongly prefer routines and predictability but simultaneously struggle to maintain routines because of difficulties with organisation and executive functioning.

They might want to know exactly what is going to happen while also becoming easily distracted or changing plans impulsively.

These experiences can sometimes feel confusing, particularly when a person has spent years trying to understand why they respond to situations differently from other people.

Can you have both autism and ADHD?

Yes.

Autism and ADHD can co-occur, and recognising this is important because having one does not automatically rule out the other.

For many years, Autism and ADHD were treated as if they could not occur together diagnostically. Current diagnostic practice recognises that a person can meet criteria for both conditions.

This means that someone may have genuine characteristics associated with autism and genuine characteristics associated with ADHD.

Understanding both can sometimes provide a more complete picture than trying to fit everything into one diagnosis.

What can autism and ADHD look like together?

Everyone's experience is different, but there can be areas where the characteristics of autism and ADHD overlap, interact or create tension.

A need for routine, but difficulty maintaining it

Autistic people may find predictability and routine helpful.

ADHD-related executive functioning difficulties can make it difficult to establish or maintain routines consistently.

A person may therefore strongly want structure while simultaneously struggling to follow it.

Intense interests and attention

Both autism and ADHD can involve periods of intense engagement with things that are particularly interesting.

However, the reasons and experiences can differ between individuals.

Someone may become deeply absorbed in a particular interest, find it difficult to shift attention away from it, or become frustrated when they are interrupted.

Sensory sensitivity and overwhelm

Sensory differences are commonly associated with autism.

For someone who is also experiencing ADHD-related difficulties with attention, impulsivity or emotional regulation, busy or overwhelming environments can be particularly challenging.

This might contribute to feeling overloaded after a day at school, work or in a socially demanding environment.

Social difficulties

ASD can involve differences in social communication and understanding social interaction.

ADHD can also affect social experiences through impulsivity, interrupting, forgetfulness or difficulty maintaining attention during conversations.

When both are present, social situations may be challenging for a range of different reasons.

Why can AuDHD feel confusing?

One reason people find the concept of AuDHD useful is that autism and ADHD can sometimes appear to pull in different directions.

You may crave predictability but struggle with routine.

You may want to focus on one thing but find your attention pulled elsewhere.

You may enjoy social connection but become exhausted by social interaction.

You may have very strong interests but struggle to organise the practical steps needed to pursue them.

This doesn't mean that every person with autism and ADHD will experience these tensions. But for some people, recognising both conditions can provide a framework for understanding experiences that previously felt contradictory.

Is AuDHD a diagnosis?

No. AuDHD is not a formal diagnostic term.

A person can receive a diagnosis of Autism Spectrum Disorder, ADHD, or both. AuDHD is an informal term that some people use to describe the experience of having both.

This distinction matters because recognising yourself in descriptions of AuDHD online is not the same as establishing whether you meet diagnostic criteria for autism or ADHD.

Online information and social media can be useful starting points, but they cannot determine whether someone has either condition.

A comprehensive assessment considers the person's developmental history, current functioning, strengths and difficulties, and whether their experiences meet the relevant diagnostic criteria.

What if I'm not sure whether it's autism, ADHD or both?

You don't necessarily need to decide which assessment you need before seeking help.

ASD and ADHD can overlap, and characteristics of either can also occur alongside learning difficulties, anxiety and other developmental or emotional factors. Trying to work out whether you need an ASD assessment, ADHD assessment or something else can therefore feel overwhelming.

At thegrowspace, we take a comprehensive approach rather than expecting you to determine the answer before you begin.We can consider the broader picture and identify which areas need to be explored, so the assessment is focused on answering the questions that are most relevant to you or your child.

Can autism and ADHD mask each other?

Sometimes.

A person may develop strategies to compensate for difficulties associated with one condition, which can make other difficulties less obvious.

For example, someone may create highly structured routines to manage ADHD-related organisational difficulties. At the same time, those routines may help them manage the predictability they prefer as an autistic person.

Others may appear to cope well externally while using significant effort to manage social, sensory, organisational or attentional demands.

This is one reason it can be helpful to look beyond whether someone simply “looks autistic” or “looks like they have ADHD”.

What if I think I might be AuDHD?

You don't need to decide whether you are “AuDHD” before seeking an assessment.

If you recognise characteristics of both autism and ADHD, it may be helpful to explore each possibility carefully.

An assessment can help determine whether you meet criteria for autism, ADHD, both, or neither, while also considering other factors that may contribute to your experiences.

The goal isn't to find a particular label.

The goal is to understand the whole person, including their strengths, challenges, preferences and the environments in which they thrive or experience difficulty.

Can the term AuDHD still be helpful?

Absolutely.

Although AuDHD isn't a diagnostic term, some people find the word validating and useful.

It can provide a simple way to describe an experience that doesn't feel fully captured by talking about autism or ADHD separately.

For some people, discovering the term helps them connect the dots between experiences they have struggled to explain for years.

For others, it may simply be a useful starting point for asking questions and seeking further information.

The important thing is to distinguish between a useful description of lived experience and a clinical diagnosis.

Wondering whether autism, ADHD or both could explain your experiences?

If you're recognising characteristics of both autism and ADHD, you don't have to work it out from online checklists.

A comprehensive assessment can help explore the bigger picture, including your developmental history, current functioning, strengths and challenges, and whether autism, ADHD or another explanation may best account for your experiences.

At thegrowspace, our focus is not simply on finding a label. It's on helping you understand yourself or your child and identifying what support may be helpful.

Note- Language preferences vary, and some people prefer ‘autistic person’ while others prefer ‘person with autism’.
