Abstract Somatoparaphrenia is a condition in which an individual has a delusional belief that a paralyzed body part contralateral to a lesion belongs to someone else. In this report, we review the literature on the lesions and concomitant symptoms of somatoparaphrenia. The lesions responsible for somatoparaphrenia have been presumed to be in the insula, the thalamus and surrounding white matter, or the medial frontal lobe. Typically, the condition is characterized by anosognosia for hemiplegia, personal neglect, and severe somatosensory disturbance. However, a recent study noted the possibility of double dissociation of anosognosia for hemiplegia and somatoparaphrenia. Moreover, there were some cases of somatoparaphrenia without personal neglect and without severe somatosensory disturbance. We also report a case of somatoparaphrenia with very mild somatosensory disturbance and absence of anosognosia for hemiplegia and personal neglect.
Keywords somatoparaphrenia, anosognosia for hemiplegia, personal neglect, somatosensory disturbance
