Been back to CAMHS and have formal diagnosis of ADHD and informal diagnosis of PDD and been referred on to get assessment for ASD. Only found out about informal diagnosis of PDD because i asked to see a copy of file and in it dr has clearly stated DS has PDD but wont formally diagnose PDD till assessment for ASD is done incase he is wrong.
So now i have all these questions about PDD that need answering becasue i always assumed PDD was autism.
