José María Morelos y Pavón facing a case of shared psychotic disorder: Nocupétaro, Intendance of Valladolid, New Spain (1799-1801)

Abstract

The shared psychotic disorder or folie à deux is a psychiatric syndrome more common than it was traditionally thought or believed until a few years ago. Two major factors have contributed in a decisive way for it to be reconsidered as a clinically significant entity: A) A better family and social environment assessment of the patients diagnosed as psychotic, and, b) the precise identification of cases, many of which are rescued from literature and history, sometimes more anecdotal than scientific. It's important to note that the more it delves into the past, it has been found that is as old as humanity itself can be. In the present research work it is describe a case that witnessed one of the most significant heroes of the American continent and the western world. The importance lies not only in the transcendence of the character involved, but about the very little described clinical variant called induced hallucinatory psychosis.
