What is a Combined Autism and ADHD Assessment?

A combined Autism and ADHD assessment explores whether an individual meets the diagnostic criteria for both:

  • Autism Spectrum Condition (ASC)

  • Attention Deficit Hyperactivity Disorder (ADHD)

Because these conditions often overlap, mask one another, or present differently when experienced together, individuals may go undiagnosed or receive incomplete diagnoses. A combined assessment ensures both neurotypes are considered together for a more accurate clinical understanding.

What is AuDHD?

AuDHD is an informal term used to describe the combined experience of being both autistic and ADHD. While not a formal clinical diagnosis, it is widely used to reflect the lived experience of having both neurotypes.

People who identify with AuDHD may experience a unique combination of strengths and challenges, including differences in:

  • Attention and focus

  • Executive functioning (planning, organisation, time management)

  • Sensory processing

  • Social communication

  • Emotional regulation

  • Energy levels and burnout cycles

A combined assessment can help clarify whether both autism and ADHD are present and how they interact in daily life.

Our combined Autism and ADHD assessment follows structured, evidence-based clinical practice and is informed by NICE guidance for both autism and ADHD assessment.

The assessment includes:
