As noted in Anatomy of an Epidemic, the prognosis for someone experiencing psychosis is far better in developing countries than in industrialized countries. Robert Whitaker and others posit that this is due to the treatment models used in the developing world, as well as to debility and chronicity caused by psychiatric drugs themselves. I think it's also important to explore traditional tribal and village based models of helping people experiencing psychosis and examine why they may be effective. Do these traditional societies know something we don't?
