Autism Diagnosis for Adults

Our adult assessments involve taking a detailed developmental history with the patient’s parents or family members. This helps give us important information about symptoms and how they featured while growing up. We also carry out diagnostic testing using the Autistic Diagnostic Observation Schedule (ADOS). The assessment process may also include some or all of the following: 

  • Clinical interview
  • Review of school reports - if available
  • Multi-disciplinary clinical discussions
  • Detailed final diagnostic report
  • Feedback appointment with one clinician (face to face or telephone)


It may sometimes be necessary to undertake an additional cognitive assessment, this helps provide information about the strengths and weakness in an intellectual profile (1.5 hours).

The findings from all the sources described are then evaluated by our Clinical Psychologist, and/or Psychiatrist, in order to consider the final diagnosis.

A full and detailed report is produced, which can be discussed during a follow-up appointment for feedback. We aim to deliver reports within 2 weeks after having completed all the stages of our assessment. If a diagnosis is made, a full explanation will be given, as well as recommendations.

Details of assessment charges can be found on our fees page.
