title: Mutism associated with buccofacial apraxia and bihemispheric lesions.
abstract: Mutism following brain trauma is quite common, is usually transient, and recovery of speech is essentially the rule. Lasting total absence of speech without aphasia is highly unusual. Three such patients, two of traumatic and one due to vascular origin showing buccofacial apraxia (BFA) and computerized tomography (CT) evidence of bilateral frontal lesions are reported. It is suggested that complete lasting mutism associated with BFA is a result of bihemispheric lesions affecting mainly the opercular part of the inferior frontal gyrus and immediate adjacent regions.
