[Psychiatric doppelganger phenomena with special consideration of the Capgras syndrome]  .
The present paper classifies and analyzes the experience of the "double" in depth. Main focus is on the Capgras experience--certainly the best known phenomenon of the double--and its possible etiology is examined. Moreover, a few other delusional experiences of mis-identification of person are also considered, such as the Frégoli phenomenon, the syndrome of subjective doubles, intermetamorphosis as well as other variants described in the literature.
