We present a patient who developed a left alien hand syndrome after a right frontal-temporal-parietal ischemic stroke. No lesion of corpus callosum or medial frontal lobe was detected. Left hemianopia, hemispatial neglect, slight hemiparesis and profound sensory loss were evident. The patient declared that the left hand "acts up as it wants". Only rarely we observed instances of intermanual conflict. During the rehabilitation training, the patient was taught to visually control the left hand: the frequency of alien hand movements gradually lessened. We hypothesize that the genesis of the alien hand syndrome in this patient could be due to coincidence of multiple factors: the profound sensory loss, the hemispatial neglect and a general attentional deficit could have been reduced the possibility of conscious perception and control of the hand, while estension of the lesion to basal ganglia could have been damaged the medial premotor system who controls voluntary movements.
