Job and school issues - can a person with schizophrenia go back to work?

Probably. With appropriate medications, many paople with schizophrenia are able to work.
Yes. Schizophrenia doesn't need to be disabling. There's folks with schizophrenia in all walks of life, even doctors. The most important thing one can do for themselves if he or she has schizophrenia is to stay on the medicine. Often, the person with schizophrenia stops taking the medication once they are better, thinking they no longer need it. Each time the person becomes psychotic, it can be worse.
