Buccofacial apraxia without aphasia due to a right parietal lesion.

Buccofacial praxis in right-handers is thought to be mediated by the left hemisphere. We present the case of a right-handed man without family history of sinistrality who exhibited a buccofacial apraxia following a unilateral right parietal infarction. Other findings such as intact language, visuospatial impairment, and hemi-inattention are more characteristic of right posterior lesions.
