Abstract

Crossed aphasia refers to disturbances of language following a purely right-hemisphere lesion in right-handed individuals. In right-handed individuals, aphasia is almost invariably related to a left cerebral lesion and crossed aphasia occurs in only 1 percent who developed a sudden left hemiparesis with global aphasia. He has neither family history of left-handedness or ambidexterity. Brain MRI showed an acute large infarct of the middle cerebral artery territory on the right side and brain SPECT disclosed extensive areas of hypoperfusion in the right hemisphere and no abnormal finding in the left hemisphere. The sensory component of language function was almost improved, but the motor component has been changed. Further studies of crossed aphasia may supply more data on the functional organization of the brain for speech and language.
