Also note that "schizophrenia" is not an illness but a family of illnesses (and even that definition is one of the less fuzzy ones). Finding a "universal cure" is as likely as finding a universal cure for cancer. That is, very unlikely.
Oh wow I didn't know that. I thought it was a neurotransmitter issue with unbalanced levels of various neurotransmitter and/or receptors, but I don't know much about it. Science will get there someday though! I guess for both cancer and complex mental illness and other types of complex illness, the trick would be to both find a workable solution to each sub-problem, and then use them to address the full complex. It would be cool if companies were working on these types of approaches. I wonder if any are?
