Unilateral neglect syndrome: clinical and topographic study of 20 subjects

Twenty patients with unilateral neglect syndrome were studied. They were 10 males and 10 females, and they ranged from 29 to 76 years of age. All were submitted to a CAT scan of the brain. Based on the findings in our sample we drew the following conclusions: the extinction phenomenon was a constant manifestation of unilateral neglect; the line crossing test proved to be most efficient for the identification of visual neglect; the right parietal lobe was the anatomical region most often involved in the unilateral neglect syndrome.
