I lived with it for ten years and now please do not insult my intelligence. My sister is an RN in charge of a whole wing in SW Wa. med center in Vancouver Wa. and was very inept at understanding what my nieces' doctors were saying and was very clear in explaining it to me.
She actually had other disorders also that that complimented her schizophrenia. We as a family supported her and when she bucked the law she paid the price and it was during her stay that she defeated her illness. Now how or why or who did it I really do not care but this I do know is that she did have it and now she does not. It is curable. You should explore the spiritual aspect of your sons illness. Putting your faith in drugs is a poor treatment choice and a last resort that leads to more drugs and so on and so on...
How wonderful for your niece that she was one of the rare few who can recover from such a debilitating illness. Sadly schizophrenia does not affect all people the same way and most are not able to recover completely. Most are lucky if medications have any effect at all, and if they can remember or know to take them (say if they have trouble with reality). What few know is that even medications are not a "cure" or even that effective. While I think it is wonderful that your family had a success story, the stats show that schizophrenia is a lifelong disorder for most diagnosed with it, so we need to come up with better options for treatment than leaving them to their own devices so they end up on the street or in prison.
You are right. It really is wonderful.
