Ipsilateral neglect in a patient following a unilateral frontal lesion.
Using a crossed-response task, it has been demonstrated that as a patient with unilateral frontal lesion recovers from visual inattention, he or she may inappropriately saccade to contralateral stimuli (visual grasp). We report a patient with a right frontal lesion who showed a similar phenomenon on sequential line bisection tasks. On day 1, he showed left-sided neglect on line bisections that enhanced with sequential trials. On day 5, he exhibited right-sided neglect (ipsilateral neglect) on line bisection tasks that also enhanced with repeated trials.
