Reduplicative paramnesia: neuroanatomical perspective on a psychiatric phenomenon
AI Summary
Sudden failure to recognise own house in a 76-year-old man was diagnosed as reduplicative paramnesia due to stroke of right anterior thalamic nuclei.
Reduplicative paramnesia is a delusional misidentification disorder frequently resulting from neurological disease and thus a neuropsychiatric phenomenon par excellence.
The case discusses clinical elements and neuroanatomical mechanisms that underlie reduplicative paramnesia, implicating right anterior thalamic dysfunction.
We describe an extraordinary case of a 76-year-old man who suddenly did not recognize his house as his own. This clinical phenomenon, a ‘reduplicative paramnesia’, turned out to be the consequence of a stroke in the anterior nuclei of the right thalamus. Reduplicative paramnesia, a delusional misidentification disorder, is often the consequence of a neurological disease and therefore a neuropsychiatric phenomenon par excellence. Through this case we further discuss the clinical elements and neuroanatomical mechanisms that underlie this phenomenon.
