Prism-adaptation Therapy for Unilateral Neglect: from the Facts to a Bottom-up Explanatory Model

Unilateral neglect is defined as the patient’s failure to report, respond to, or orient toward novel and/or meaningful stimuli presented to the side opposite to the brain lesion [1, 2, 3]. This syndrome is frequently consecutive to the damage of the right brain hemisphere. It often is in association with contralesional hemiplegia, hemianesthesia and hemianopia. Several types of motor deficits have been described in unilateral neglect, ranging from motor neglect or extinction to perturbations of intentional aspects of action.
