My own son, now aged 19 was a SEN child, it took me years to get his school to help him and they always labelled him 'restless', he wasn't overly naughty just didn't like to be told off for things he didn't do, he hates injustice still now. Eventually at the age of 13 in a different wonderful school, they finally realised something was needed and he got fully tested and is on the autistic spectrum, with small ADHD tendencies. I was so tempted to go to his junior school headmistress and say, stick that in your pipe and smoke it as it were and it breaks my heart that they failed him so much. It also gave many in my larger family circle a realisation that there is autistic tendancies in many, reaching as far as grandparents etc. My own hubby also being told he was probably autistic too. But as my sons psychiatrist said, you don't grow out of it, you learn to adapt, as my hubby and son have done and they have had to re learn how things are done differently, which is sad really. My son is now at uni doing computer science and still struggles but he does the best he can.
Still some people in our life don't know this about him and I have never claimed benefits and hate it when people make light of this kind of thing and don't understand.
