| Annotation | The epidemiology, aetiology, neuroanatomy and neuropsychology of the Capgras syndrome (CS) is reviewed in this article. CS is characterised by the delusional belief that one or a few highly familiar people have been replaced by impostors who are physically very similar to the original(s). The syndrome is relatively rare, and was traditionally considered to have its origins in psychodynamic conflict. More recently, however, it has been estimated that between 25 and 40% of cases are associated with organic disorders, which include dementia, epilepsy and cerebrovascular disease. Neuroimaging evidence suggest a link between CS and right hemisphere abnormalities. Neuropsychological research has provided empirical support for these findings by consistently reporting the presence of impairments in facial processing - an established right hemisphere function. The study of this symptom may lead to a greater understanding of the neurological basis of psychotic experiences and may provide a paradigm for how the psychoses should be investigated. (AKM). |
