Nice To Talk To U Doctor. My Sister Was Diagnised

Nice to talk to u doctor. My sister was diagnised with paranoid schizophrenia in 2001. Then doctor suggested her Oleanz and rispond plus. Till date she is taking those medicines regularly. But she was not perfectly cured. Mainly she had hallucinations that she was continuously scolded by a neighbouring family of us at that time. Later we shifted that house. Still she is saying the same thing. Moreover 6 years back she started saying that she was loved by a man. But she dont know him. She will marry only him. Later she started saying that that boy relatives are chasing her and they are commenting her to marry him. Some times she is very normal. Sometimes she says that she will marry any boy whom we suggest. But sometimes she says she will marry only that boy who loves her.If u see her U say that I am telling lies. what is the solution for this? My mail id is YYYY@YYYY . I am waiting for ur reply. Thank You Very Much Doctor.
