P008 - Capgras Syndrome and Criminal Behavior

• In Event: Poster Session & Ice Cream Social

Abstract

Capgras Syndrome is described as a delusional belief that loved ones, objects, animals, or places have been replaced by impostors or duplicates. It's an extremely rare condition, with available epidemiological data suggesting a prevalence of about 0.12% in the general population, with a female-to-male ratio of 3:2, while in the psychiatric population it rises to about 1.3%. This condition, which affects the perception of others' identity, also has significant criminological implications. Its association with criminal behavior highlights the need for legal and psychological depth to adequately support the judicial process in cases involving affected individuals. Distinguishing Capgras Syndrome from other disorders, such as schizophrenia spectrum disorders and dissociative disorders, is crucial for accurate diagnosis and targeted treatment. The most common comorbidities include schizophrenia, mood disorders, neurodegenerative disorders, and organic diseases. Etiological hypotheses proposed to date include functional, organic factors, and substance abuse. Exploring its criminological implications can offer important insights for intervention strategies and support in legal evaluation, requiring interdisciplinary collaboration among psychiatrists, psychologists, criminologists, and legal professionals for a holistic approach that considers the multiple dimensions involved in this complex syndrome.
