The patient declares these doubles to be both psychologically and physically completely identical to him, and he believes ‘them’ to be in fact women.

The strong parallels in the etiology and course of the three cases justify the positing of a syndrome, here termed reduplicative paramnesia, and a neuropsychologic analysis of the disorder stresses the cognitive operations entailed in geographical localization and confabulation.
