Approximately 21% of children with ADHD are also autistic, with others having heightened autistic traits¹
While they are separate diagnoses, ADHD and Autism (ASD) frequently occur together with many people meeting the criteria for both, leading to the informal community term ‘AuDHD’.
Research suggests a significant number of autistic people also have ADHD⁴, and vice versa.
Both conditions begin in childhood and affect brain development, they often impact attention, executive function, and social life in similar ways. These overlapping symptoms can sometimes complicate a diagnosis, making a specialist assessment essential to untangle the two.
Clinicians often use the DSM-5 diagnostic manual when assessing ADHD and autism. In the past, older versions of this manual actually prevented a dual diagnosis, making it very difficult to identify both together.
This changed when newer guidelines removed that restriction. If you have ever wondered, ‘can you be diagnosed with ADHD and autism’ at once, the answer is now a clear yes, which is why more people are now discovering they have a combination of both.
Autism is primarily characterised by unique ways of communicating and experiencing the world. Many people find comfort in clear rules and predictable routines, often developing a deep, expert-level knowledge of specific interests.
Difficult concentrating can arise from ADHD, Anxiety or a combination of both.
becasue anxiety and ADHD influence attention in different ways, distinguihing between them often depends on understanding long term patterns rather than individual symptoms.
ADHD and anxiety rarely look like the “hyperactive child” stereotype in adults. Many people learn to hide the struggle by over-preparing, working late and using endless reminders, so from the outside they seem capable while feeling constantly behind inside.
When you also have anxiety or low mood, professionals can easily focus on those first and not ask about the lifelong pattern of focus, organisation and impulsivity. That’s why so many adults reach assessment feeling unseen and doubting themselves.
Treatment plans for ADHD and anxiety are individual. Clinicians usually look at which symptoms are causing you most difficulty and may focus there first, or work on both together using a mix of medication and talking therapies.
Support for ADHD can include stimulant or non-stimulant medication, psychoeducation, and practical strategies for organisation, time-management and planning.
Some people also benefit from coaching or CBT that is adapted to ADHD and focuses on building daily routines and managing impulsivity.
Anxiety is commonly treated with psychological therapies such as cognitive behavioural therapy (CBT).
Where appropriate, a GP or mental health team may also offer medication such as SSRIs, alongside lifestyle support around sleep, stress and physical health.
Some tools can ease both ADHD and anxiety at the same time, for example CBT, learning to break tasks into smaller steps, using structured planners, improving sleep, regular physical activity and reducing alcohol.
Following assessment, a clinician can explain which approaches may be most helpful and discuss appropriate next steps.
In a world where creativity flows like a river, the sun rises over the hills, casting golden rays on the vibrant flowers.
ADHD and anxiety together can make everyday life feel like constant firefighting. At work or in your studies, that might look like missed deadlines, last-minute rushing, performance nerves and a nagging fear you’ll be “found out” as less capable. At home, lateness and forgetfulness can be read as not caring, which can lead to arguments or you pulling away because you feel overwhelmed.
Over time, many people start to feel they are always “under-achieving” despite how hard they try, and that can slide into burnout. Small changes will not replace assessment or treatment, but they can make daily life a bit easier – for example keeping one central to-do list, using clear visual reminders for key tasks, and breaking larger jobs into smaller, manageable steps.

Yes. Many adults with ADHD also experience an anxiety disorder, so having both is common and means you may need support for two linked conditions, not just one.
