Abstract

Mental health is a private matter, which refers to an individual’s cognition and emotion; more precisely, it describes the condition of one’s mind. The slogan “no health without mental health” has been proposed by the world health organization (WHO) for a few years (1). According to statistics, almost 450 million people suffer from mental or neurological diseases.
