A group of rare but fascinating neuropsychiatric conditions in which a person misidentifies people, places, objects—or even themselves. These misidentifications are not due to memory loss or confusion but are held with delusional conviction, meaning the belief persists despite clear evidence to the contrary.
🧠 Key Subtypes:
- Capgras Syndrome:
The belief that a loved one has been replaced by an identical impostor. - Fregoli Delusion:
The belief that different people are actually one person in disguise. - Intermetamorphosis:
Belief that people around the patient have swapped identities with each other physically or psychologically. - Reduplicative Paramnesia:
The belief that a familiar place exists in multiple locations simultaneously.
