I think I've read somewhere that 80% of all the cases of schizophrenia can be accounted for by genes, which makes the progression of schizophrenia almost unavoidable (at least with current treatment options). At any rate I don't think you can understand schizophrenia well if you say it's a mainly psychological disorder like most cases of anxiety and depression, so I think they're over-emphasizing the psychological part here. But apart from that this was a good read, and I completely agree with what they're saying about therapy. Thanks!

PS: I have no doubts that what I have is more of a brain disease than a psychological disorder. Not saying it's like that for everyone though.
