The neural basis of anosognosia for spatial neglect after stroke
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 …

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.
