Prism adaptation improves egocentric but not allocentric unilateral neglect. A case study
BACKGROUND: Rehabilitation of unilateral neglect has focused on the ego-centric form of the disturbance. However, allocentric neglect is known to predict failure in the activities of daily life even more than egocentric neglect. CASE REPORT: We submitted a patient with severe egocentric and allocentric left-sided neglect to an extensive prism adaptation training. After treatment, the patient persisted in errors on the left side of targets (allocentric neglect) and actually it increased in parallel with her increased exploration of left space (egocentric neglect).
