[The stigma mental health bears. A challenge for the 21st century].

The authors make an in-depth study about the reasons why a mental health stigma perseveres in our society by means of a conceptual analysis, a summary of recent historical development in psychiatry and mental health in Spain, and diverse evidence obtained from recent studies in this field. The authors emphasize the usefulness of critical documentation to contrast traditional academic interpretations and requisite interest of research studies which lead to reflection and a guide for professional nursing practice.
