Answer

Answer

Issues with neglect are commonly seen with a right hemisphere infarct. Patients with neglect have significant impairment in functional mobility. Multiple theories have been advanced on the neurophysiological basis of neglect. These theories include the attention-arousal theory, [57] hemispheric specialization, [58] disengagement theory [59] , and interhemispheric interaction and inhibition. [60]
