    Abstract

    Foreign Accent Syndrome (FAS) is a well-known neurological deficit Whose underlying cause has remained obscure despite almost a century of study. Combining structural and functional imaging, our Studies suggest that FAS represents a compensatory response to impaired motor regulation of speech. We describe a patient who acquired FAS as a result of an ischemic stroke in the left basal ganglia. In addition to this case being exceptionally clean, we were able to confirm a specific lesion location as well as provide strong evidence that impaired motor speech regulation resulted in compensation by other areas of the cortical motor speech network.
