Hi! My name is Rituraj and I am currently staying in Bangalore. I have a friend whom I have know for more than 3 years. He used to be a guy who was always filled with energy and he used to be very helpful. But after his father passed away in January 2011, he has completely changed. As of now, he does not socialize with anyone. He loves to stay alone. His through process is somewhat weird and he does not seem to be a normal person anymore. He is also on substance abuse and he hallucinates some times. My friends and I have tried speaking with him, but to no avail. I read an article on Schizophrenia recently, and I have seen that my friend has similar symptoms to that of a schizophrenic patient. I am not sure of it though! I want to help my friend and I would really appreciate if you could kindly advice on what needs to be done. Thanking you!

Hi, I appreciate your concern for your friend. You guess right that he may have schizophrenia. But for me, it is difficult to say confirm diagnosis without evaluation. He may have depression also. You can do one thing for him. Convince him to consult a psychiatrist and take him to SIMIANS, Bangalore or any private psychiatrist. Psychiatrist will evaluate and reach to diagnosis and start the treatment. If he is not ready to come, you can go to psychiatrist and narrate his situation. If any family member of him who is aware about him in detail, you can also take him/her to the psychiatrist for detail evaluation. If feasible, then psychiatrist can do home visit on request of relative. After that treatment can be started. If he is in condition where his physical and mental health in so danger that survival is the issue, he can be forcefully treated according to law. For that psychiatrist can guide you more in detail. All the best. Regards, Chat Doctor.
