[Crossed buccofacial apraxia].

Praxis and language are considered right hemisphere functions. Buccofacial apraxia, except few occasions, are seen in right-handed patients with left hemisphere lesions with aphasia. We present a right-handed patient with buccofacial apraxia due to an ischaemic lesion of the right hemisphere seen by MRI. Language was normal and there was not limb apraxia in our patient. It is possible that in some individuals the control of voluntary movements of facial muscles is not associated neither to the control of language neither to the learning of complex movements of limbs.
