Schizophrenia is one of the most persistent and disabling mental illness that an individual can suffer from. It is generally accepted that a certain defect in brain- chemical or structural, or both- causes a predisposition to Schizophrenia, which may then be brought on by external causes such as stress or emotional upheaval.
The illness is not inherited but rather the tendancy to get it can inherit. Scientist generally agree that Schizophrenia is a group of conditions rather than one simple disease. A cure for it is to be discovered. Although a cure has not yet been found, it may be successfully treated.
