7 yr old could he have autism

[poppy2008]

Hello
My 7yr old is very difficult at the moment he will not listen when I give him a row he cannot keep eye contact when talking to him. He is kicking off about anything even very little things and cries over anything, he has no space awareness and is frequently getting naked at inappropriate times. He seems to find it difficult to play in groups? And he as went back to putting things in his mouth.Help not sure why he's doing this

Thank you I have got an appointment tomorrow at Gps this will be the first time I have fully raised my concerns. We thought he may have been going through puberty early due to his emotions and other signs but that was ruled out and he was signed of from the hospital

Would the consultants you saw at the hospital refer for assessment? They have obviously logged and investigated behaviours and found no cause so can now refer onto another department who can investigate.
I would think it's helpful for you that behavioural issues have already been recognised and logged.

If the behaviour is out of the blue I would ask for a blood test.
It my be a deficiency of some sort. A boy in our village had a sudden onset of asd symptoms with no history of that behaviour from being a toddler, he was found to have an iron and b12 deficiency.
He was put on supplements and recovered over a few months.

Of course that may not be the case of all, but might be worth checking.
