Schizophrenia: Symptoms may worsen over time. This can include social isolation, lack of self-care and cognitive decline.

Variable: COmpletely depends on the environment,and specific sx. We would say most often not a good choice. Treatment however should NEVER really be only meds, support , structure, being on a good routine with HEALTHY eating choices, Essential fatty acids and nutritional supplementation(if indicated) Can and Do help a LOT. Meds often do also , They are just another tool(Dig a hole-take a shovel)
