PDA Autism or not???

Hi I was wondering if anyone could help me. My sons 5 and is currently awaiting a autism diagnosis. His school have raised concerns of possible PDA (pathological demand avoidance). I have raised this to the peadiatrician and CAHMS. Both have had opposite opinions on it, peadatrician says it's not a diagnosis and to forget about it basically. CAHMS on the other hand haven't dismissed it but haven't agreed either. My question now is can it be diagnosed in Hertfordshire and how does it get diagnosed if the peadatrician wont even acknowledge it???!!! 

  • Hi Marley,

    I'm not sure on the particular situation in Hertfordshire but you will find more information on PDA in the PDA section of the NAS website https://www.autism.org.uk/about/what-is/pda.aspx
