ADHD kind of symptoms to my son.

Hi My son is having below symptoms 1. Not able to focus on his studies for long time (not more than 15 to 30min mostly)  on any subjects either while his teacher teaching or during we are teaching in Home. If he ask to write his home work as well he hesitate a lot. 2.Running inside home or jumping from bed or sofa even aftet we cautioned him that he might get hurt if he do all these things. He says he will not do it But still  he is not control himself and repeat the same again. 3. With his brother or while xplaying anything mostly he is not playing softly. He is bit rough on any of his activities Kindly help us to provide some guidance on how to improve his behaviour and also make him focus on his studies like other kids. As a parent we are very much worried. Regards Jegan
