Délire de jalousie et syndrome de Capgras : à propos d’un cas de paranoïa

Abstract

Capgras syndrome or Capgras delusion is part of the psychiatric classification of delusional misidentification syndromes. The patient is able to identify the facial features of his close relations but is maintaining that they have been replaced by double (identical substitutes) that are absolutely identical. This syndrome associates, as Capgras and Reboul-Lachaux stressed it, a feeling of strangeness and a feeling of familiarity. The patient perceives the similarity with his close relation but cannot recognize the identity. Using a clinical case of paranoia, which associates jealousy delusion and Capgras syndrome, and a study of the concept of double, we will underline the relevance of psychodynamic theories.
