How efficient is a simple copying task to diagnose spatial neglect in its chronic phase?
Twenty-five patients with spatial neglect were tested in the acute phase and about 1.3 years after a right-hemisphere stroke. Ten patients had developed chronic spatial neglect. We investigated how sensitive a simple copying task is in detecting spatial neglect in the chronic phase. When the stroke was acute, all 10 patients omitted a considerable number of contralesionally located items in the copying task. In the chronic phase, 60% of the chronic neglect patients still demonstrated noticeable neglect in the copying task. The data indicate that a simple task such as the copying of a multi-object scene is a helpful tool to detect residual symptoms of spatial neglect even more than 1 year after the stroke.
