Hello, this is our first post, parents of a 12 yr old AS boy, diagnosed 2 years ago (which didn't help). Over the past 12 months we have noticed a change in his skills, mainly loss of language skills, mobility and immaturity. i.e. he said "this is raw" meaning that his water he was drinking was warm, "we have run out of bed" meaning bread, "don't forget the jam" meaning gel, and not knowing what "incorrect" meant. Also in school, he left yr 6 on level 2, (after just reading Harry Potter and the Philosophers Stone all by himself and understanding it) he is now at a level of 1/2 across the board. Does anyone else or has anyone had this happen to them at all?
