BACKGROUND AND PURPOSE: The present study investigated the lesion anatomy of anosognosia for visuospatial neglect resulting from right hemispheric stroke.
METHODS: In 63 patients, self-ratings of performance in paper-and-pencil tests were contrasted with external performance ratings. Lesion analysis was conducted on patient subgroups with different degrees of anosognosia but comparable visuospatial impairment.
RESULTS: Independent of the severity of visuospatial neglect per se, damage to the right angular and superior temporal gyrus was associated with higher levels of anosognosia.
CONCLUSIONS: Using a novel assessment of anosognosia for spatial neglect, the present study relates stroke-induced self-awareness deficits to inferior parietal and superior temporal brain damage.
