hi by the sounds of it he is just like my friends son he is 10 he has ADHD and aspergus . if he has got ADHD then he would play up where ever he is at school,home,out and about, anywhere kids that do have ADHD dont like change and need to have a routine. like for instance if they ask when is dinner going to be done and you say at 4 o.clock then they would expect to have it at that time and if they dont get it a 4 then they will get very aggitated and play up alot. ADHD children also say very hurtfull things sometimes , but they dont meen it. take him to the doctors and see what they suggest . they will prob want school reports as your child would spend half their time at school . hope this helps youout a bit ..
i am not a dr but it doesnt sound like adhd. i have adhd and i was diagnoised unfortunately at age 34 back in the days they were clueless on what adhd was. do you feed him alot of sugar or addtive colors and dye food. try gettng him evaluated for adhd. there are several searches you can do yourself to see if he has it but your best bet is to get him evaluated for it. i hope that helps. usually adhd is related to poor focus, concentration hyperactivity, restlessness and i can go on. google adhd for children. hope it helps.
