title: Reduplicative paramnesia.
abstract: A striking behavioral abnormality is described in three individuals who had severe head trauma. At a point when general mnestic capabilities had returned to a near normal level, the patients persistently relocated the hospital at another geographical site, even in the face of compelling counter-evidence. The strong parallels in the etiology and course of the three cases justify the positing of a syndrome, here termed reduplicative paramnesia. A neuropsychologic analysis of the disorder stresses the cognitive operations entailed in geographical localization and confabulation. Clinical-pathologic considerations underline the role of right hemisphere and frontal lobe structures in the syndrome.
