Delusional misidentification syndromes
Capgras Syndrome	Hypofamiliarity	The belief an individual, often a spouse or family member, has been replaced with an identical body double. In rare cases, the imposter can replace inanimate objects or animals. Reverse Capgras syndrome: Individuals believe they have been replaced by an imposter, most commonly a revered or famous individual while maintaining their original physical attributes.
Fregoli Syndrome	Hyperfamiliarity	Patients often believe a stranger is a known individual (frequently a spouse or family member) in disguise. Reverse Fregoli syndrome: The belief that others, known to the individual, cannot recognize them.
Intermetamorphosis	Hyperfamiliarity	The belief is that people, usually familiar to the patient, are swapping identities although maintaining appearance. Reverse intermetamorphosis: The belief that one has morphed identities while maintaining physical appearance.
Syndrome of Subjective Doubles	Hyperfamiliarity	The belief is that there is a body double of the patient living and functioning independently of the patient.
Asomatosognosis	Hypofamiliarity	The belief is that part of their body is missing or has disappeared from the person's awareness. Somatoparaphrenia: A subtype where patients exhibit hemiplegia with delusional misidentification and confabulation.
Cotard Syndrome	Hypofamiliarity	The belief is that one is dead or dying, including a sense of rot or loss of organs.
Delusional Companion Syndrome	Hyperfamiliarity	Patients believe objects, often inanimate, possess the ability to feel emotions, have independent thinking, and have a consciousness.
