The purpose of this research is to present multidisciplinary and relevance of Thanatology in coping of addictions and other mental disorders.

The aim of this paper is to analyse the scientific connections that thanatology establishes with other knowledge. With this postulate we present the thanatology and its relations with other disciplines, especially psychiatry, considering that addictions and mental disorders often have as triggering events of loss, death and mourning.

To develop this research we use the systematic literature review, following the process of research, cataloging, careful evaluation and synthesis of the documentation.

Thanatology is multidisciplinary shares and receives information from other sciences or sectors of knowledge without these modified or enriched. It is interdisciplinary because it originated disciplinary specialty of a mother discipline: Anthropology; and it is transdisciplinary, thence its relevance in research on the realities that revolve around mental disorders and addictions (Fig. 1).

It is important to research on thanatology position in the scientific panorama, given the emergence of this reflection and the relevance of research for its interrelationship with other disciplines.
