Abstract:
In the psychiatric literature, the phenomenon of the doppelganger or double is characterized into different types of delusional misidentification syndromes and heautoscopic symptoms. Specifically, we focus attention on heautoscopy, which might also be named "dissociative" after excluding an organic etiology. We report a case of heautoscopy in a woman and discuss the clinical variability of this psychopathological phenomenon. Furthermore, a short treatment of the historical and literary implications of this delusion is presented.
