Mental health literacy is the beliefs and knowledge about mental health issues and their remedies. Attitudes and beliefs of lay individuals about mental illness are shaped by personal knowledge about mental illness, knowing and interacting with someone living with mental illness, and cultural stereotypes. Mental health issues are increasing and are alarming in almost every part of the world, and hence compiling this review provides an opportunity to understand the different views regarding mental disorders and problems as well as to fill the gap in the published literature by focusing only on the belief system and perception of mental health problems among general population.
