Anomalous Presentation of Capgras Syndrome in an Adolescent: A Case Report and Literature Review

Capgras syndrome is a rare delusional disorder characterized by the belief that a close family member or acquaintance has been replaced by an identical impostor. Although it is typically associated with psychiatric disorders such as schizophrenia or neurological conditions like dementia, this syndrome usually presents in adults. We report a case of an adolescent female presenting with Capgras syndrome, which was not associated with any primary psychiatric or neurological disorder. This report aims to explore the rarity of this presentation, the diagnostic challenges it poses, and the implications for treatment. Additionally, this case highlights the importance of considering atypical presentations of psychiatric syndromes in young patients. The report concludes with a discussion on the existing literature, methodological considerations in psychiatric case studies, and directions for future research.
