[Buccofacial apraxia without limb apraxia or aphasia after right premotor area contusion: a case report].

ABSTRACT

Facial apraxia, as well as aphasia, has been associated with lesions in the cerebral hemisphere contralateral to the dominant hand. We describe a patient with severe facial apraxia caused by contusion in the right frontal operculum, premotor area and primary motor cortex ipsilateral to the dominant hand. The patient had no aphasia or limb apraxia. Magnetic resonance images of the brain reveal no abnormality of the hemisphere contralateral to the dominant hand. Thus, in some individuals, facial praxis is controlled by the hemisphere non-dominant for both handedness and language.
