(How can PDA be diagnosed if it’s not in the diagnostic manuals?)

Whilst PDA is not mentioned in the diagnostic manuals that many clinicians refer to, a PDA profile can be identified as part of an autism assessment and terminology such as “Autistic with a PDA profile” used. This use of ‘specifiers’ to personalise and contextualise a diagnosis and helpful support approaches is encouraged by the European Society for Child & Adolescent Psychiatry and The Lancet Commission on Autism. Further details can be found in the Identifying & Assessing a PDA Profile Practice Guidance.
