Mental Illness:
In the core term, mental illness is a type of psychological anomaly or disturbance that is mostly reflected in the behavior and not a part of the normal or common development of a person’s culture.

Although the understanding and the recognition to such mental condition have changed and evolved in the course of time and within different cultures, there are still different variations in the classification, assessment, and also the definition of the ailment itself.
