Is a process schizophrenia curable ?

No cure: "process" schizophrenia is an older term for what we now think of as chronic schizophrenia. Although a variety to interventions, including medications, supportive therapy, and family work, can greatly improve quality of life and markedly reduce symptoms, we do not have a true cure of the illness, nor do we seem to be close to finding one. It tends to wax and wane & treatment adherence is key.
