Abstract

Anosognosia for hemiplegia (AHP), i.e., unawareness of motor deficits and associated disorders, has been frequently reported, predominantly followingright hemispheric lesions. To a smaller extent, there are case reports of patients who give accounts of a feeling of strangeness concerning the contralesional limbs and sometimes attribute them to other persons. This "positive-variant" of AHP has been labeled "somatoparaphrenia" (SP). We report a case of SP in a 85-year-old woman with infarction of the rightposterior cerebral artery and posterior parts of the right thalamus. She showed AHP and described her left side alternatively as her handicapped nephew and a clumsy cat. Misidentification of her daughter also occurred. With respect to the literature the predominant neuroanatomical features involvedare lesions including right parietal cortex and/or posterior parts of the thalamus. Theories concerning the pathogenesis of this phenomenon comprise a denial of the illness, a lack of awareness caused by reduced sensory feedback and neglect, a misidentification or disturbance of the active discovery process considered necessary for realizing one's disorder.
