The article draws on scientific literature to provide a sociological explanation of society's attitude towards mental disorders, and the impact this has on access to mental health care systems. In this literature review, we examine the various sociological mechanisms that act as barriers to access to mental health care, and which inevitably give rise to a crisis of trust between the patient; who develops a disorder; and the system; that is supposed to treat him or her. The domino effect reaps dramatic consequences, the stinging example of which is the annual suicide figure of 700,000 human beings. In the course of this article, we will audit the sociological causes, from which we will draw the cultural link and its dominant beliefs, and then all the other barriers that can complicate each and every stage of access to adequate mental care. With a solid grasp of the sociological barriers, it will then be time to list the generic principles of an acceptable mental health care system we’re aiming for, before addressing the issues of trust and stigmatization and explaining the link between them. Finally, the article concludes with a summary of the situation and some suggested recommendations. We recommend a diversified range of services, including the possibility of home support; continuity and agility in treatment; a new methodology in the distribution of care; with an increase in the quality of either the informations and proximity services available; thus, we can’t stress enough the importance of adapting practitioner training to increase empathy.
