This thesis proposes to discuss the social representations of the madness and the social place of the individual with a mental disorder, whose objective is articulated with the evaluation of Paulo Amarante (2007) on the importance of the sociocultural dimension related to the developments of the Brazilian Psychiatric Reform for the process of deinstitutionalization, which provides for the social reintegration of people with mental disorder. The Theory of Social Representations for its procedural approach, with Serge Moscovici, Denise Jodelet and Angela Arruda, supports the understanding and the approximation of the object worked. The Cartography of Deleuze and Guattari, also accessed through the reading of Virginia Kastrup and Roberta Romagnoli, and the Content Analysis of Bardin (2011) are the theoretical-methodological tools used to follow the process and the analysis of the material produced by the 29 interviewees in the two fields of research. Content analysis shows the social representations of the individual with a mental disorder with simultaneous and polar characteristics of agitation and aggressiveness or tranquility and docility, and also as someone who is not normal. The house and the family were pointed out as a social place to be occupied by the same, and not the psychiatric hospitals. Madness was represented as a disease, disorder, requiring medication for its control and facilitation of social interaction, but also the therapies were pointed out as an essential part of the treatment. The community still offers resistance to living with people with mental disorder for fear of violence and material loss, asking them to be hospitalized. Institutionalization was represented as necessary in times of crisis or outbreak of the individual with a mental disorder. The finer and / or singular contours related to the mapping of social representations can be identified in the cartographic exercise from three chosen interviews and, in the expression of the images produced by the researcher, using the visual language to approach aspects of the object and the process as one all.
