Patient discussion about separator

Q. I have adapted my 6 year old son. He stays separate and alone. I am suspecting him to be having autism? I have adapted my 6 year old son from an orphanage. He was looking great that I could not leave him there. He stays separate and alone, away from his other friends. He cannot make friendship. I have seen that he does not make any eye contact when we talk to him. Initially I thought that he will know me well then he will be ok. But it’s not happening after 3 years since I had brought him from the orphanage. Even he cannot talk well. I am suspecting him to be having autism?

A. He may have autism. You must take him to a doctor. Now his history and his parent’s information can reveal the genetic impact of his autism. In order to get all these information’s, try to get in touch with the orphanage. Tests taken by the doctor like behavior assessment and other tests will confirm about his autism. But don’t worry he can become well if you will work hard to help in his behavior treatment and learning. But don’t lose confidence in the kid though you have adapted him from the orphanage.
