Persistent Broca's aphasia after right cerebral infarct ion in a right‐hander

Abstract

A strongly right-handed man developed sudden mutism and left hemiplegia 2 days after a myocardial infarct. Evaluation 6 1/2 years later revealed persistent Broca's aphasia. There was no clinical, CT, or EEG evidence of left brain injury or disease. This case is another example of dissociation of cerebral dominance for speech and handedness. However, the severe and persistent language disorder is rare. The paucity of documented case reports supports the traditional view of strong interdependence of handedness and speech cerebral lateralization.
