Can somebody help me? I'm trying to fill in the PIP form for my 16 year old son who has aspergers syndrome. I don't know what to use as evidence or who to put down as a health professional. The school senco said I couldn't put down her when I asked, the GP hasn't seen him since he was about 10 and the paediatrician who diagnosed him hasn't seen him since his diagnosis aged 9. I haven't got any paperwork since his diagnosis letter and he is currently on a long term DLA award that he's had since 2015.
