With the right effective dose of medication, adherence to treatment, and a support network, as well as the commitment to developing and using coping skills, it's possible the long-term prognosis for someone diagnosed with schizophrenia will be good, and the hardship lessen.
If you look up information on the internet about the prognosis for those with schizophrenia, I think you will find studies that show that sz often gets a little better with age. It kindof eases off and stabilizes at a lower level. Not so many peaks and valleys. Best wishes.
