Summary of "The dynamic nature of the sense of ownership after brain injury. Clues from asomatognosia and somatoparaphrenia."

The sense of ownership is the feeling that a body part belongs to ourselves. Brain damage may disrupt this feeling, leading to somatoparaphrenia (SP), i.e., the delusion that one's limbs belong to someone else. This delusional feeling is typically associated with profound motor and somatosensory deficits. We reviewed the cases of SP reported so far in the literature outlining the clinical and neuroanatomical profile of SP. We then investigated and reported three new peculiar cases of SP that allow new insights into the theoretical framework of this neuropsychological condition. We thus propose an innovative theoretical account that integrates previous evidence and the new cases described. We suggest that a defective update of the ongoing dynamic representation of the body finalised to perception and action, may be the key for the disownership feelings of patients with SP. The erroneous spatial representation of the limb contralateral to the lesion would have the logical consequence of delusional misattribution of the seen own arm.

Medical and Biotech [MESH] Definitions

Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.

Prolonged unconsciousness from which the individual cannot be aroused, associated with traumatic injuries to the BRAIN. This may be defined as unconsciousness persisting for 6 hours or longer. Coma results from injury to both cerebral hemispheres or the RETICULAR FORMATION of the BRAIN STEM. Contributing mechanisms include DIFFUSE AXONAL INJURY and BRAIN EDEMA. (From J Neurotrauma 1997 Oct;14(10):699-713)

Conditions characterized by persistent brain damage or dysfunction as sequelae of cranial trauma. This disorder may result from DIFFUSE AXONAL INJURY; INTRACRANIAL HEMORRHAGES; BRAIN EDEMA; and other conditions. Clinical features may include DEMENTIA; focal neurologic deficits; PERSISTENT VEGETATIVE STATE; AKINETIC MUTISM; or COMA.

An injury in which the damage is located on the opposite side of the primary impact site. A blow to the back of head which results in contrecoup injury to the frontal lobes of the brain is the most common type.

A form of acquired brain injury which occurs when a sudden trauma causes damage to the brain.
