Assessing visual extinction in right-hemisphere stroke patients with and without neglect

Introduction: Visual neglect and extinction are two common neurological syndromes in patients with right-hemispheric brain damage. The question of how these two syndromes are associated is still a matter of debate. Since – contrary to the diagnosis of neglect – no standardized tests exist for the assessment of visual extinction, we aimed to investigate the relationship between the two syndromes in right-hemispheric stroke patients by using a novel standardized experimental task. Methods: Sixty patients with right-hemispheric stroke (including 18 patients with spatial neglect) and 18 healthy controls performed a…
