Well not to be too discouraging but they have basically shown that the meds cause a certain level of brain loss over time...a lot of that used to be attributed to the disease but now based on animal studies and medicated vs non medicated people they know it's the drugs...all those classic images that show differences between people which sz vs controls those were people on meds...still if I had to choose psychosis or meds I would choose meds even knowing the risk...it's a quality of life thing...I mean with full psychosis I could never hold down a job or probably even keep my friends because of the way I was thinking and interacting and you seem to develop more delusions over time so if one doesn't apply there is always another...

Have you ever tried any cognitive remediation with her to take advantage of neuroplasticity? She is still young so her brain should be pretty flexible. You might want to read about Barbara Arrowsmith....there are special schools that focus on people who think differently....arrowsmith was amazing she read about brain theory with some difficulty and designed work that would fix her own brain because she had a learning disability and now she does this for other kids some of the exercises seem weird like learning to read analog clocks or wearing an eyepatch over one eye but they are specifically designed to deal with certain brain connectivity issues. They have to be repeated to solidify the connections In the brain. She only vaguely discusses the techniques in her book but her techniques are so successful that she basically sells packages to schools to use the methods so it's possible you could convince a local school to pick it up you know.

Anyway check out her website...

Another thing to check out is posit...they are devolving software that was based on actual testing of people with sz and cognitive remediation...
Brain Training Software, Brain Fitness, Brain Games, BrainHQ - Posit Science | Your Brain Health Headquarters

Both of these types of programs are a lot of sort of boring work but seem to result in permanent gains to thinking and brain function...so there is natural modification of brain connectivity that can really improve things...
