[Reduplicative paramnesia: neuroanatomical perspective on a psychiatric phenomenon]
Abstract:
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.

Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
