title: Delusional reduplication following closed-head injury.
abstract: Somatic delusions following brain injury are not uncommon, and have been well documented in the literature. This study documents a case of somatic delusion which was seen in a patient following a head injury secondary to a motorcycle accident. Although perhaps not typical it serves to illustrate an interesting example of a somatic delusion following head trauma. On recovery from coma this patient reported the existence of a 'third arm' adjacent to the limb that had received the greatest impact in the accident. The patient was unreceptive to any counter-persuasions and in fact remained largely unconcerned about this addition to his anatomy. A thorough neuropsychological evaluation was carried out in an attempt to seek an explanation for this phenomenon. The results suggest that the phenomenon has at least a partly psychiatric aetiology rather than a purely neurological foundation.
