Abstract

In this paper, we report the case of a man in his 30s with a first-episode psychosis, characterised by a subtype of delusional misidentification syndrome in which the delusion of doubles is exclusively of the patient’s own self. This subdivision can be termed ‘syndrome of doubles of the self’ or ‘syndrome of subjective doubles’. Additionally, an examination of the patient’s mental state showed paranoid delusions. After being evaluated in the emergency department, the patient was hospitalised, and medicated with antipsychotic drugs. One week later, he was discharged with total remission of psychotic symptoms. This is a rare and curious presentation of a psychotic episode, with very few similar cases described to date.
