Delirium e confusão mental no século XIX: Uma história conceitual

Abstract

Delirium remained a stable psychiatric category until the early 19th century when it underwent aetiological and phenomenological redefinition, precipitating the transformation of the functional insanities into psychoses. Confusion, introduced by the French during the second half of the century, referred to a syndrome wider than (but including) delirium. It emphasized chaotic thinking and cognitive failure. The notion of clouding of consciousness (and tempora-spatial disorientation) established a common denominator for the two concepts, while Chaslin and Bonhoeffer redefined confusion and delirium asthe stereotyped manifestations of acute brain failure. © 2009 Associação Universitária de Pesquisa em Psicopatologia Fundamental.
