Hi, Thanks for asking. In my opinion your child seems to have ADHD. If such a child comes in my clinic I would like to assess him for ADHD and put him on stimulant medications like Methylphenidate. I would also suggest parents to make some behavioural modification for him. Pre determined consequenses for his good and bad behaviour will help tackle his behaviour better. Also it needs to be assessed that is his poor school performance is due to ADHD or he has some associated learning disability. I hope I have helped you. Thank you.
