A joined up assessment pathway for adults where there are signs of both ADHD and autism

Combined Adult ADHD and Autism Assessment

A comprehensive Consultant Psychiatrist-led assessment for adults where there are indications of both ADHD and autism.
ADHD and autism can share similar characteristics, and many adults experience traits of both. Our combined assessment provides a thorough evaluation of both conditions within a single assessment pathway, helping you gain a clearer understanding of your experiences and, where appropriate, a diagnosis and personalised recommendations.

Is a combined assessment right for you?
A combined assessment may be appropriate if you:
  • Recognise characteristics associated with both ADHD and autism
  • Experience difficulties with attention, organisation or executive functioning
  • Find social communication or relationships challenging
  • Experience sensory sensitivities or rely on routines
  • Already have one diagnosis and wish to explore whether the other condition may also be present
  • Would benefit from one assessment that considers both conditions together.
What your assessment includes
Your assessment is carried out by an experienced Consultant Psychiatrist and includes:
  • A detailed clinical interview
  • Exploration of your developmental history
  • Assessment of ADHD symptoms and autism characteristics
  • Consideration of recognised diagnostic criteria
  • Review of relevant questionnaires and supporting information where appropriate
  • A comprehensive diagnostic report
  • Personalised recommendations, where appropriate
Our approach
  • Every assessment is Consultant Psychiatrist-led and follows recognised diagnostic criteria and current NICE guidance.
  • Your Consultant Psychiatrist considers how your experiences fit across both conditions, recognising where characteristics overlap and where they are distinct, to build a comprehensive understanding of your presentation.
  • Our aim is to provide a clear, evidence-based understanding of your strengths, challenges and any diagnoses that may be appropriate.
