How long do schitzophrenics have what is called a “psychotic episode” normally and how frequently they reoccur?
Without medications a person who has Schizophrenia is usually in a psychotic state all of the time, this is the voices and the hallucinations. A paranoid Schizophrenic is the dangerous one without medications. They may act on what the voices are telling them to do what they hear is always negative, there is no way of telling how long an episode of acting out dangerously can last. But there is no reason for this behavior or the voices, hallucinations, etc to occur as there are very good medications that prevent the symtoms the voices, etc. I hope that whoever you are asking about is getting treatment and taking medications as ordered.
