Speech suppression without aphasia after bilateral perisylvian softenings (bilateral rolandic operculum damage).

The authors describe a patient who suffered two successive, right and left, strokes that caused bilateral rolandic operculum damage. The clinical picture was characterized by selective impairment of volitional facio-pharyngo-glosso-masticatory movements with sparing of automatic and reflex motor activity (Foix-Chavany-Marie syndrome). Though completely speechless, the patient was not aphasic. This dissociation is discussed in the light of the peculiar localization of lesions evidenced by CT-scan.
