I'm less familiar with the psychiatric side of it, although I have done a project with a psychiatric team. Honestly, as far as I know, there has been very little advances in treating schizophrenia. Most treatment (involving medication) pretty much just blasts the brain and shuts it down (hence why a lot of patients eventually go off medication, the side-effects are terrible). One of the reasons for why so little advancement has been made is because we really still don't have a clear picture of what schizophrenia is. Lots of research teams investigate their own little topic, but not many connections have been made between those topics.
