RT Journal Article SR Electronic T1 Opticosensory ataxia and alien hand syndrome after posterior cerebral artery territory infarction JF Neurology JO Neurology FD Lippincott Williams & Wilkins SP 1094 OP 1094 DO 10.1212/WNL.36.8.1094 VO 36 IS 8 A1 Levine, David N. A1 Rinn, William E. YR 1986 UL http://n.neurology.org/content/36/8/1094.abstract AB A right-handed woman developed left homonymous hemianopia and left hemianesthesia from infarction due to right posterior cerebral artery occlusion. Ataxia of the left arm and leg was severe and was not improved by vision. The patient often interpreted spontaneous movements of the left arm as alien in origin. The ataxia may have been caused by a combination of sensory ataxia, resulting from right thalamic infarction, and crossed-optic ataxia, resulting from posterior disconnection of the hemispheres due to right temporo-occipital infarction. This opticosensory ataxia was associated with a new form of “alien hand” syndrome.
