AuDHD in Teenagers: Understanding the Overlap Between Autism and ADHD
The term AuDHD is increasingly being used to describe young people who experience traits of both autism and ADHD, although it is not currently a formal clinical diagnosis
In this week’s Let’s All Talk Mental Health session, host Tara Dolby was joined by resident clinical psychologist Dr Sarah-Jane Knight to explore how autism and ADHD can overlap in teenagers, why adolescence can be a particularly challenging time for neurodivergent young people, and how parents can focus on practical and appropriate support, rather than getting too caught up in labels.
“AuDHD”
One of the first points Sarah-Jane made was that AuDHD is not currently a formal diagnosis. Clinically, autism and ADHD are separate neurodevelopmental conditions, although it is common for them to appear together.
If a young person has a diagnosis of autism, the likelihood of also having ADHD is significantly higher than in the general population. Equally, someone with ADHD may show autistic traits such as sensory sensitivities or difficulties with social processing. Rather than focusing too heavily on labels, Sarah-Jane emphasised that it’s more helpful to understand the individual profile of the young person:
What are the areas they struggle with most?
What situations overwhelm them?
What helps them regulate and cope?
Diagnosis can be important for accessing support and services, but ultimately it is the support plan around the individual that will make the greatest difference.
Why Adolescence Can Be Difficult
Adolescence is a period of huge developmental change for any young person. Hormonal changes, social pressures and increasing independence all place greater demands on emotional regulation and executive functioning. For teens with autistic and ADHD traits, this stage can feel particularly intense. School environments often require students to:
Sit still for long periods
Manage multiple subjects and classrooms
Navigate complex social situations
Handle increasing academic pressure
For some neurodivergent teens this level of demand can be exhausting. Sarah-Jane reassured parents that adolescence can sometimes be a particularly intense phase, but it does not define the future. Young people who seem unsettled at 13 or 14 may look very different by their early twenties as their brains mature and the right support strategies take effect.
The Challenge of Everyday Demands
One of the biggest areas of difficulty for many neurodivergent teens is executive functioning which are the set of skills that help us organise, plan and manage daily life.
This includes things like:
remembering homework
organising school materials
planning tasks
managing time
initiating work
In mainstream schools these skills are often assumed rather than taught, which can leave some students feeling overwhelmed. Parents may need to provide more structure and practical support than expected for their teen’s age. Helping with things like packing a school bag, organising tasks or planning revision can reduce stress significantly while those skills are still developing.
Recognising Signs of Burnout
When demands exceed a young person’s coping capacity, burnout can occur. Burnout can look like:
increased emotional reactivity
withdrawal or shutdown
reduced resilience to everyday stress
exhaustion after school
a drop in coping skills
Many parents see this most clearly after school, when their teen finally releases the pressure they have been holding together during the day. Allowing some emotional decompression with clear boundaries can help. For example:
offering quiet recovery time after school
reducing unnecessary demands
building predictable routines
supporting emotional literacy
Emotional Literacy Matters
One area Sarah-Jane encouraged parents to focus on is emotional literacy to help teenagers recognise and name what they are feeling. Some young people naturally develop this skill, while others need more support. Simple suggestions included:
naming emotions in everyday conversation
reflecting feelings back to your teen
discussing what helps when they feel overwhelmed
identifying triggers and coping strategies together
Developing these skills gives young people tools they can use throughout their life, not just during adolescence.
Adjustments That Can Help
Many of the strategies that support neurodivergent teens are actually quite simple and can include:
quiet spaces for regulation
movement breaks during the day
predictable routines
sensory adjustments at home
regular opportunities to reset after school
Sarah-Jane mentioned that some of these adjustments are already common in specialist schools but can be harder to implement in mainstream environments. Even small changes, however, can significantly reduce stress for a young person.
Talking to Your Teen About Their Profile
When discussing neurodiversity with teenagers, Sarah-Jane suggested avoiding complicated terminology where possible and instead focusing on understanding their personal profile. A helpful suggestion was to create a simple mind map together:
What situations feel stressful?
What triggers overwhelm?
What helps them regulate?
What strategies have worked before?
This approach shifts the focus from diagnosis to problem-solving and empowerment.
What We Know as Parents
Perhaps the most reassuring message of the session was that parents already hold an important advantage: they know their child better than anyone else. While diagnoses can be helpful, parents often know their child better than anyone else, and that understanding can be just as important when working out what support will help most. By focusing on what helps their individual child regulate, cope and thrive, parents can help build support mechanisms that go beyond adolescence.
Takeaway
Neurodevelopmental labels can sometimes feel confusing or overwhelming, especially when new terms appear in online conversations. Rather than becoming too focused on labels, parents can make the greatest difference by:
understanding their child’s individual profile
identifying triggers and supports
building practical strategies together
supporting emotional literacy and regulation
Every young person’s neurodevelopmental profile is unique. With patience, structure and supportive relationships, many teenagers gradually develop the skills they need to navigate the world in their own way.
