Hi Doctor. Let me clarify the issue in detail. I have my cousin who is at the age of 33 now. He Was brilliant in studies and little shy till 15. He draw things beautifully on his school days. But after that he was weird. He speaks to himself or talking about some other things continously and making some noises, waves his hands simply, too much depressing himself for a value and invaluable reason. Because of that he failed in his 10th board exams. Till now he do the same things. He tried his 10th exams four times attempt, but he could not clear it. But his memory is strong enough that he could tell things that happen 10 or 15 years before.Now he cannot able to draw what he did before. His parents took him to doctor and they gave him becostar tablets. He uses once or twice a day. He is following this prescription since 7 years. But no kind of improvement. Doctor please tell me that do he have some solutons for it. Looking forward for your reply Doctor.
