My brother is being extremely unbearable these days. He also had these symptoms of beating his head and speaking intensely rudely six months back. We took the help of a psychiatrist, where he was diagnosed and treated for schizophrenia, after which he became normal. He was taking Zisper and Zapiz. Two years later, after college admission, he started taking medicines on his own, but in the hostel, he again dropped into addiction. For three months, he has become extremely rude, not attending classes and not studying anything. What should we do? Should we consult a psychologist or psychiatrist?
