Which type of schizophrenia is the worst type?

Any Type Possible: The worst type of schizophrenia is the type that causes the greatest impairment in one's ability to function and does not respond to medical treatment. In the U.S. We recognize five sub-types of schizophrenia: paranoid, disorganized, catatonic, undifferentiated, and residual. Some studies show that the paranoid type may have a better prognosis for indepdent living than the other four.

All are bad: While any kind of schizophrenia is difficult, schizophrenia with a prominence of negative symptoms ca be more difficult to treat, and more disabling.

Schizophrenia: Prognosis is worst if schizophrenia is of the disorganized type with delusions of persecution, also in schizophrenias that are resistant to treatment and chronic.
