abstract = {Objective: Reduced awareness for motor or cognitive
impairments has mainly been studied in relation to
right-hemispheric deficits such as left-sided hemiparesis.
However, recent studies suggest that also left hemisphere
(LH) stroke can lead to reduced awareness for
neurological/neuropsychological deficits, for example,
aphasia. The aim of the current study was to characterize
reduced awareness for apraxic as well as aphasic deficits in
patients suffering from LH stroke. Method: After the
assessment of apraxia and aphasia, patients (n = 32) were
asked to rate their performance on a 1- to 5-point rating
scale. An unawareness score (UAS) was computed as the
difference between the examiners’ ratings and
self-ratings, resulting in negative scores for patients who
overestimated their performance in a given assessment, that
is, exhibited reduced awareness for their stroke-related
deficits. Results: Patients with apraxia (n = 14) and
aphasia (n = 16) significantly overestimated their
performance in the respective assessment. However, the level
of awareness was not generally related to the severity of
apraxia, and there were no group differences in other
variables between patients with full (n = 7) and reduced
awareness (n = 7) for apraxic deficits. The reduction of
awareness for apraxic deficits did not differ significantly
for buccofacial versus limb gestures. Conclusion: Data show
that LH stroke can lead to reduced awareness not only for
aphasic deficits but also for buccofacial and limb apraxia.},
