schizophrenia doesn’t have an exact known cause, however family dysfunction can be one of them. for instance, the environment where the individual grows up in or lives in can have an effect on whether someone develops this disorder. a person’s environment should be stable and healthy, but if that’s not the case and the family is dysfunctional, then there’s high levels of stress in the household and this might cause neurotoxic reactions within the brain that eventually leads to these individuals being vulnerable and developing this order or making it harder for them to maintain and deal with the disorder
