Schizophrenia: Is it preventable

Schizophrenia can be defined as the most severe psychiatric disorder which causes bizarre behavior, withdrawal from the reality, emotional instability and disorganized speech and thinking. Schizophrenia is a widespread issue because it does not only affect the individual itself but rather the family taking care of the person as well. Due to the fact that the person tend to suffer from disordered thoughts with the disease, they become ineffective in communicating with others. Schizophrenia is not dominant in any race or a particular sex in the population. It usually strikes the individual around the ages of fifteen and forty years which has a great impact on youth but never before fifteen or after the age of forty.
