Head Injury from falling down. Happened.

My uncle fell down from stairs & hurt it's back side of the head. He was rushed to the hospital. Blood was clotted in the back side & above the ears. The doctor suggested operation of back side to pull out the clotted blood & hence conducted it successfully. But the clotted blood above ears was said to be treated with the help of medicine. The medication is under process. He opened his eyes after two days of the operation & was able to recognize the people present there. The problem started after 4-5 days when he was recovering & has started to speak few things. After this on one day he suddenly became a bit impatient & started requesting his family member that he wants to go home. The situation started to become worse , now most of the time he is in anxiety & have started to throw few punches towards his own son & relative for not letting him go to his home. Abusive words , facial expressions make him look as if some great tragedy has happened.
