Somatoparaphrenia
Somatoparaphrenia (pronunciation: /soʊˌmætoʊˌpærəˈfriːniə/) is a type of monothematic delusion where one denies ownership of a limb or an entire side of one's body.
Etymology
The term "somatoparaphrenia" is derived from the Greek words "soma" meaning body, "para" meaning beside or near, and "phrenia" meaning mind.
Definition
Somatoparaphrenia is a neuropsychological disorder characterized by the patient's denial of ownership of one or more of their limbs, usually the left arm. Despite clear evidence of ownership, patients with somatoparaphrenia continue to disown their limbs. This condition is often associated with right hemisphere brain damage, particularly to the right parietal lobe.
Symptoms
The primary symptom of somatoparaphrenia is the denial of ownership of a limb or limbs. This can manifest in a variety of ways, such as the patient claiming the limb belongs to someone else, or that it has been replaced with a prosthetic. Other symptoms can include anosognosia (lack of awareness or denial of an illness), hemispatial neglect (neglect of space on the opposite side to the damaged hemisphere), and sometimes hallucinations.
