In recent years, the term AuDHD has become increasingly recognised across the neurodivergent community, healthcare settings and online discussions. While it may be unfamiliar to many people, AuDHD is helping individuals better understand an experience that was historically difficult to explain the experience of living with both Attention Deficit Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD).
For many people, discovering the term AuDHD can feel like finally finding a missing piece of the puzzle. It can provide an explanation for lifelong experiences that may have previously seemed confusing or even contradictory. Some individuals have spent years wondering why they relate strongly to both ADHD and Autism, while others may have received a diagnosis for one condition only to later discover that another neurodevelopmental condition has also been present.
Although AuDHD is not a formal medical diagnosis, it has become a widely accepted term used to describe individuals who meet the diagnostic criteria for both ADHD and Autism. As awareness continues to grow, clinicians are recognising that understanding how these conditions interact is essential for providing accurate assessments, meaningful support and personalised treatment recommendations.
At Invictus Health, we understand that every neurodivergent individual experiences the world differently. Whether you’re seeking answers for yourself, your child or someone you care about, understanding AuDHD is an important step towards recognising strengths, identifying challenges and accessing the right support.
What Does AuDHD Mean?
The term AuDHD combines two neurodevelopmental conditions:
- Autism Spectrum Disorder (ASD)
- Attention Deficit Hyperactivity Disorder (ADHD)
Rather than describing a separate condition, AuDHD refers to individuals who meet the diagnostic criteria for both Autism and ADHD.
Historically, many people believed that Autism and ADHD were completely separate conditions. In fact, until relatively recently, clinicians were generally unable to diagnose both conditions in the same individual. As research evolved, however, our understanding of neurodevelopment also changed.
Today, healthcare professionals recognise that ADHD and Autism frequently occur together. Research has shown there is considerable overlap between the two conditions, with many individuals experiencing characteristics associated with both.
While every person is unique, people with AuDHD often describe experiencing a combination of characteristics that can sometimes seem to conflict with one another. For example, someone may thrive on routine and predictability while also craving novelty and stimulation. They may experience intense focus on topics they enjoy while simultaneously struggling to maintain attention on everyday tasks.
These experiences are not contradictory they reflect the complex interaction between two different neurodevelopmental conditions.
Is AuDHD an Official Diagnosis?
This is one of the most common questions people ask.
The short answer is no.
AuDHD is not currently recognised as a separate diagnosis within the Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR), which is the diagnostic framework commonly used by clinicians in Australia and internationally.
Instead, AuDHD is an informal term used to describe individuals who have both ADHD and Autism.
Although the term itself is relatively new, the concept is not. Research over the past decade has demonstrated that co-occurring ADHD and Autism are far more common than previously understood.
The growing popularity of the term reflects increasing awareness among clinicians, researchers and the neurodivergent community that many people experience both conditions simultaneously.
For many individuals, using the term AuDHD simply provides an easier way to describe their lived experience than repeatedly saying “I have both ADHD and Autism.”
Can Someone Have Both ADHD and Autism?
Yes.
Current clinical understanding recognises that ADHD and Autism can occur together, and many people receive diagnoses for both conditions.
In fact, studies have found that there is significant overlap between ADHD and Autism. Many individuals initially seek assessment for one condition before discovering that characteristics of the other condition have also been present throughout their lives.
This is particularly common among adults who may have developed effective coping strategies over many years.
For example, someone may seek an ADHD assessment because they experience difficulties with organisation, attention and emotional regulation. During the assessment process, clinicians may also identify longstanding differences in communication, sensory processing or repetitive behaviours that indicate Autism.
Similarly, an individual seeking an Autism assessment may discover that many of the executive functioning challenges they’ve experienced are more consistent with ADHD.
Understanding the interaction between both conditions is one reason why comprehensive assessments are so important.
Why Are More People Talking About AuDHD?
If you’ve only recently started hearing the term AuDHD, you’re not alone.
There are several reasons why awareness has increased significantly in recent years.
Improved Clinical Understanding
Researchers and healthcare professionals now have a much better understanding of how ADHD and Autism can coexist. Rather than viewing the conditions separately, clinicians increasingly recognise that they often overlap and influence one another.
This has led to more comprehensive assessments and greater awareness of individuals who may previously have received only one diagnosis.
Greater Public Awareness
Social media, podcasts, books and online communities have helped increase awareness of neurodiversity.
While online information should never replace a comprehensive clinical assessment, it has encouraged many people to seek professional advice after recognising experiences similar to their own.
As awareness grows, more individuals are learning about AuDHD for the first time and recognising that it may explain challenges they’ve experienced throughout childhood or adulthood.
Better Recognition in Adults
Historically, ADHD and Autism were more commonly identified during childhood.
Today, clinicians recognise that many adults reached adulthood without receiving an assessment, particularly women and individuals who developed strong masking or coping strategies.
As a result, more adults are now pursuing ADHD and Autism assessments after years of wondering why everyday tasks, relationships or workplaces have always felt more difficult than they seem for others.
ADHD and Autism: Understanding the Similarities and Differences
Although ADHD and Autism are distinct neurodevelopmental conditions, they share a number of characteristics that can make diagnosis more complex.
Both conditions can affect communication, executive functioning, emotional regulation and social interactions. However, the reasons behind these experiences are often different.
For example, a person with ADHD may interrupt conversations because their thoughts move quickly and they struggle with impulse control. An autistic person may interrupt because they are highly engaged in a topic or find conversational timing difficult to interpret.
Similarly, both conditions may involve difficulties with attention, but for different reasons.
Someone with ADHD often struggles to regulate attention, finding it difficult to maintain focus on tasks that are repetitive or uninteresting. In contrast, an autistic individual may demonstrate exceptionally strong attention to areas of personal interest while finding other environments overwhelming due to sensory input or cognitive demands.
When ADHD and Autism occur together, these characteristics can interact in unique ways.
For example, an individual may crave structure and routine while simultaneously feeling restless or seeking novelty. They may enjoy predictable environments but become bored by repetitive activities. They may experience intense interests while also finding it difficult to organise the tasks required to pursue those interests consistently.
These seemingly conflicting experiences are often what lead many people to first discover the concept of AuDHD.
Common Signs and Characteristics of AuDHD
Every person with AuDHD is unique. No two individuals will experience ADHD and Autism in exactly the same way, and the balance of traits can vary significantly from person to person.
Some people may experience stronger ADHD characteristics, while others find their autistic traits are more prominent. For many individuals, the interaction between the two conditions creates an experience that feels quite different from living with ADHD or Autism alone.
Because AuDHD combines two neurodevelopmental conditions, the characteristics often overlap, complement one another or even appear to conflict. This is one of the reasons many people spend years trying to understand themselves before receiving an accurate assessment.
Some of the most common characteristics of AuDHD include:
Differences with Attention and Concentration
One of the defining features of ADHD is difficulty regulating attention rather than simply having a lack of attention.
Many people assume ADHD means someone is unable to focus. In reality, individuals with ADHD often experience fluctuating attention. They may struggle to concentrate on routine tasks but become completely immersed in activities they find interesting, a phenomenon often referred to as hyperfocus.
When Autism is also present, this can become even more complex.
An autistic person may naturally develop deep, specialised interests and enjoy spending long periods learning about a particular topic. Combined with ADHD hyperfocus, this can lead to periods of exceptional concentration followed by difficulty returning to everyday responsibilities.
For example, someone may spend hours researching a favourite topic while forgetting to eat lunch, respond to messages or complete important work tasks. This isn’t due to laziness or a lack of motivation. Instead, it reflects differences in how the brain regulates attention and prioritises information.
Executive Functioning Challenges
Executive functioning refers to the brain’s ability to plan, organise, prioritise, remember information and manage daily tasks.
Many people with AuDHD experience executive functioning difficulties that affect almost every aspect of daily life.
This might include:
- Starting tasks but struggling to finish them.
- Feeling overwhelmed by large projects.
- Frequently losing important items.
- Difficulty estimating how long tasks will take.
- Forgetting appointments or commitments.
- Struggling to switch between activities.
- Feeling mentally exhausted after organising daily responsibilities.
These challenges often occur despite the individual wanting to complete tasks successfully.
Many adults with AuDHD describe feeling frustrated because they know what needs to be done but find it difficult to begin or maintain momentum. Others become overwhelmed by the number of small decisions involved in everyday life, leading to procrastination or burnout.
Understanding these executive functioning differences can be incredibly validating, as they reflect genuine neurological differences rather than poor motivation or a lack of effort.
Sensory Sensitivities
Sensory processing differences are commonly associated with Autism but are also experienced by many people with ADHD.
Individuals with AuDHD may notice heightened sensitivity to:
- Loud or unexpected noises
- Bright lighting
- Certain fabrics or clothing textures
- Food textures or flavours
- Strong smells
- Busy environments
- Multiple conversations happening at once
Everyday environments such as shopping centres, classrooms, workplaces or public transport can become overwhelming because the brain is processing significantly more sensory information than expected.
Some individuals also experience sensory seeking behaviours, enjoying movement, pressure, certain textures or repetitive activities that help regulate their nervous system.
Understanding sensory differences often explains why environments that seem manageable for others can feel exhausting for someone with AuDHD.
Social Communication
Autistic individuals often experience differences in social communication, while people with ADHD may experience impulsive communication styles.
When both conditions occur together, social interactions can become particularly complex.
Some individuals may:
- Interrupt conversations unintentionally.
- Miss social cues.
- Talk at length about topics they enjoy.
- Struggle with small talk.
- Find group conversations overwhelming.
- Feel exhausted after social situations.
- Replay conversations afterwards, worrying they said the wrong thing.
Importantly, these experiences do not mean someone lacks empathy or wants to avoid relationships.
Many people with AuDHD deeply value friendships and meaningful connections but may find the social expectations surrounding communication confusing or mentally draining.
Emotional Regulation
Many children and adults with AuDHD experience heightened emotional responses.
Emotions may feel incredibly intense, and it can sometimes be difficult to regulate feelings once they become overwhelming.
This may include:
- Becoming frustrated quickly.
- Feeling overwhelmed by unexpected change.
- Difficulty calming after conflict.
- Increased anxiety.
- Feeling emotionally exhausted after busy days.
- Experiencing rejection sensitivity.
These emotional responses are not a sign of being “too sensitive.”
Instead, they reflect differences in how the nervous system processes stress, sensory information and emotional experiences.
Learning emotional regulation strategies can significantly improve wellbeing once someone understands why these reactions occur.
The Push and Pull Between Routine and Novelty
One of the most commonly described experiences of AuDHD is feeling pulled in two different directions.
Many autistic individuals find comfort in routine, predictability and familiar environments.
In contrast, ADHD often seeks novelty, stimulation and variety.
This can create an internal conflict.
For example, someone may carefully plan their entire week because routines help them feel calm.
Then, halfway through the week, they may suddenly become restless, bored and crave something completely different.
Likewise, an individual might desperately want structure but struggle to maintain routines because ADHD makes consistency difficult.
These seemingly contradictory experiences are often one of the strongest indicators that both ADHD and Autism may be present.
Why AuDHD Is Often Missed
Despite increasing awareness, many people spend years without recognising they may have both ADHD and Autism.
Historically, clinicians tended to focus on identifying one condition rather than considering both together. If an individual met the criteria for Autism, ADHD characteristics were sometimes overlooked. Likewise, someone diagnosed with ADHD may never have received a comprehensive Autism assessment.
This has changed significantly over recent years, but many adults today grew up before this improved understanding became common practice.
Another reason AuDHD is frequently missed is because the characteristics of one condition can mask or compensate for the other.
For example, ADHD may make someone appear highly social and talkative, while underlying autistic differences in communication or sensory processing remain unnoticed.
Conversely, an autistic person’s preference for routine may help compensate for ADHD-related organisation difficulties, making those challenges less obvious during childhood.
As life becomes more demanding through university, employment, parenting or independent living, these coping strategies may no longer be enough. Many people then begin seeking answers after experiencing increased stress, anxiety or burnout.
Receiving an accurate assessment later in life often helps explain experiences that previously felt confusing or difficult to understand.
AuDHD in Adults
Although awareness is improving, many adults are only now discovering they may have AuDHD.
For years, they may have been told they were disorganised, overly emotional, lazy, shy, sensitive or simply “different.”
Many learned to hide their struggles by developing sophisticated coping strategies known as masking.
Masking involves consciously or unconsciously adapting behaviour to fit social expectations. This might include rehearsing conversations before social events, copying other people’s communication styles, forcing eye contact despite discomfort or suppressing repetitive behaviours.
While masking can help someone navigate work, school or relationships, it often comes at a significant emotional cost.
Many adults with AuDHD describe feeling exhausted after social interactions, constantly analysing conversations or feeling as though they are performing rather than simply being themselves.
Others experience repeated cycles of burnout, particularly when trying to meet workplace expectations while managing executive functioning challenges and sensory overload.
For many adults, receiving a diagnosis can be an incredibly validating experience. Rather than changing who they are, it helps explain why certain aspects of life have always required considerably more effort.
An assessment can also open the door to practical strategies, workplace adjustments, psychological support and, where appropriate, medication or other interventions that improve day-to-day functioning and overall quality of life.
AuDHD in Children
Children with AuDHD often experience the world in ways that differ from their peers. While every child is unique, having both ADHD and Autism can influence how they learn, communicate, regulate emotions and interact with others.
Some children may appear highly energetic, impulsive and constantly on the move, while also finding comfort in routines, becoming overwhelmed by changes to their environment or experiencing sensory sensitivities. Others may have intense interests, struggle with transitions, find it difficult to manage friendships or become emotionally overwhelmed more easily than expected for their age.
At school, children with AuDHD may experience challenges such as:
- Difficulty maintaining attention during lessons.
- Forgetting instructions or losing belongings.
- Becoming overwhelmed by busy classrooms or noisy playgrounds.
- Difficulty understanding social expectations.
- Strong emotional reactions to unexpected changes.
- Challenges with planning, organisation or completing tasks.
- Feeling exhausted after masking throughout the school day.
It’s important to remember that these behaviours are not simply “bad behaviour” or a lack of effort. They reflect genuine differences in how a child’s brain processes information, emotions and their environment.
Early identification allows children to better understand themselves while also giving families, educators and healthcare professionals the opportunity to implement strategies that support learning, emotional wellbeing and healthy development.
For many families, obtaining an assessment provides reassurance and clarity. Rather than focusing solely on challenges, it helps identify a child’s strengths while ensuring they receive the support they need to thrive both at school and at home.
Why an Accurate Assessment Matters
Living with undiagnosed ADHD, Autism or AuDHD can be frustrating.
Many individuals spend years questioning why everyday tasks seem more difficult than they appear for other people. They may blame themselves for struggling with organisation, relationships, communication or emotional regulation without realising these experiences may be linked to underlying neurodevelopmental differences.
A comprehensive assessment can provide answers.
Receiving a diagnosis isn’t about applying a label. Instead, it provides a clearer understanding of how an individual’s brain works and why they experience the world differently.
An accurate assessment can help:
- Better understand personal strengths and challenges.
- Identify appropriate supports and interventions.
- Inform school learning plans or workplace accommodations.
- Improve relationships through greater self-awareness.
- Access evidence-based therapies where appropriate.
- Explore medication options for ADHD if clinically recommended.
- Reduce feelings of self-blame by providing a clearer explanation for lifelong experiences.
- Build confidence through greater understanding of neurodiversity.
For parents, an assessment can also provide valuable guidance on how best to support their child’s learning, emotional development and overall wellbeing.
How Are ADHD and Autism Assessments Completed?
Every assessment is tailored to the individual.
At Invictus Health, our clinicians undertake comprehensive neurodevelopmental assessments designed to build a detailed understanding of each person’s experiences, developmental history and current presentation.
Depending on the individual’s age and circumstances, an assessment may include:
- Clinical interviews.
- A detailed developmental history.
- Standardised assessment tools.
- Behavioural observations.
- Cognitive and functional assessments where appropriate.
- Parent or caregiver interviews.
- Teacher questionnaires or school reports for children.
- Review of previous medical or psychological information.
Because ADHD and Autism frequently overlap, clinicians carefully consider whether characteristics of one or both conditions are present.
Rather than focusing on a single symptom, the assessment examines the individual’s overall pattern of strengths, challenges and developmental experiences.
Following the assessment, the clinician discusses the findings in detail and provides recommendations that may include ongoing psychological support, educational strategies, workplace adjustments, referrals or, where appropriate, medical treatment.
The goal is not simply to determine whether diagnostic criteria are met, but to provide meaningful information that helps individuals better understand themselves and confidently move forward.
When Should You Consider an Assessment?
Many people wonder whether their experiences are simply part of their personality or whether they may reflect an underlying neurodevelopmental condition.
While everyone occasionally experiences distraction, forgetfulness or social challenges, it may be worth considering an assessment if these experiences have been present for many years and are having a significant impact on daily life.
You may wish to seek an ADHD or Autism assessment if you or your child:
- Frequently struggles with attention, organisation or completing everyday tasks.
- Experiences sensory sensitivities that interfere with daily activities.
- Finds social interactions confusing, exhausting or overwhelming.
- Has intense interests alongside executive functioning difficulties.
- Experiences emotional regulation challenges or frequent overwhelm.
- Has always felt “different” without understanding why.
- Has previously been diagnosed with ADHD or Autism but believes characteristics of the other condition may also be present.
- Is experiencing ongoing difficulties at school, university, work or within relationships.
Seeking an assessment is not about finding something “wrong.” It is about gaining a better understanding of how your brain works so that appropriate supports and strategies can be put in place.

Final Thoughts
Understanding AuDHD has helped many people finally make sense of experiences they’ve lived with for years.
While ADHD and Autism are distinct neurodevelopmental conditions, they frequently occur together. Recognising how these conditions interact allows individuals, families and healthcare professionals to better understand strengths, identify challenges and develop strategies that support long-term success.
Whether you’re exploring AuDHD for the first time, seeking answers for your child or considering an assessment as an adult, remember that every neurodivergent experience is different.
The most important step is seeking accurate information and, where appropriate, a comprehensive assessment from qualified healthcare professionals.
With the right understanding and support, individuals with ADHD, Autism and AuDHD can thrive in education, employment, relationships and everyday life.
Frequently Asked Questions About AuDHD
What is AuDHD?
AuDHD is a commonly used term that describes someone who has both Attention Deficit Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). Although it is not a formal medical diagnosis, it is widely used by clinicians, researchers and the neurodivergent community to describe co-occurring ADHD and Autism.
Is AuDHD an official diagnosis?
No. AuDHD is not listed as a separate diagnosis in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR). Instead, it refers to individuals who meet the diagnostic criteria for both ADHD and Autism.
Can someone have both ADHD and Autism?
Yes. Current clinical evidence shows that ADHD and Autism can occur together. Many children and adults meet the diagnostic criteria for both conditions, and comprehensive assessments help clinicians identify how these neurodevelopmental conditions interact.
What are the most common signs of AuDHD?
Common characteristics may include executive functioning difficulties, sensory sensitivities, emotional regulation challenges, differences in social communication, fluctuating attention, hyperfocus, impulsivity and a combination of seeking both routine and novelty. Every individual experiences AuDHD differently.
Can adults be diagnosed with AuDHD?
Yes. Many adults receive an ADHD and Autism diagnosis later in life after recognising lifelong patterns that were previously misunderstood or masked. An adult assessment can provide valuable insight into workplace challenges, relationships, emotional wellbeing and executive functioning.
Can children have AuDHD?
Yes. Children can experience both ADHD and Autism simultaneously. Early assessment can help families better understand their child’s strengths and challenges while supporting access to appropriate educational, psychological and therapeutic services.
Why is AuDHD sometimes missed?
Because ADHD and Autism share overlapping characteristics, one condition may mask the other. Many individuals also develop coping strategies or masking behaviours that make characteristics less obvious, particularly during childhood. Comprehensive assessments help clinicians identify the full neurodevelopmental picture.
How is AuDHD assessed?
There is no separate AuDHD assessment. Instead, clinicians complete comprehensive ADHD and Autism assessments using clinical interviews, developmental history, standardised assessment tools and information from parents, caregivers, teachers or other healthcare professionals where appropriate.
Do I need a referral for an ADHD or Autism assessment?
In many cases, no. At Invictus Health, individuals can self-refer by contacting our team directly. Referrals from GPs, paediatricians or other healthcare professionals are also welcome and may provide useful background information during the assessment process.
What should I do if I think I have AuDHD?
If you recognise characteristics of both ADHD and Autism and these experiences are affecting your daily life, consider speaking with a qualified healthcare professional about a comprehensive neurodevelopmental assessment. An accurate assessment can provide greater understanding, personalised recommendations and access to appropriate supports where needed.
Does a diagnosis mean I need medication?
No. Medication is one option among several, and many people manage well without it. Following assessment, we can provide psychological therapy, practical strategies for executive functioning, emotional regulation and sensory needs, and recommendations for school or workplace adjustments – all available through Invictus Health.
Can Invictus Health prescribe ADHD medication?
No. Our assessments are conducted by psychologists and clinical neuropsychologists, who do not prescribe medication. In Victoria, ADHD medication is prescribed and managed by psychiatrists and, for children, paediatricians. From late 2026, a small number of specially trained GPs will also be able to diagnose ADHD and prescribe. If medication is something you wish to explore, our comprehensive assessment report can support and streamline your referral to a prescriber.
