What Is The Cure For Schizophrnia Disease?

Hi, Sir, Good Morning. Its abount my mother who is at her 65 years of age, staying in Bangalore, Karnataka. She is suffering schizophrenia (i feel) for last 22 years. We have consuled famous dctoers in Bangalore like Dr.HS Narayana, Dr. Chandrashekhar of NIMHANS, Bangalore, All are Allapathy treatment. Nothing is working out. Tabs like sizopin, qutipin etc given. Shocktreatments many times given by the doctors but no vain. She hates ladies of any age, keeps on talking herself, tablets/food stopped taking. Won t take home food. Very suspicious about others, especially about ladies of my home. She loks very normal, even talks very normal with outer people. Some time people will get doubt whether she has this type of deases? Now a days she is going out of the house, and don t wants to come back. She loves a lot to my father.
