Foreign accent syndrome in a patient with multiple sclerosis.

BACKGROUND

Foreign accent syndrome is a speech disorder which leads listeners to perceive the patient as having a foreign accent. It has been recognized previously after stroke, brain injury or unknown causes.

CASE REPORT: A 52-year-old woman with clinically definite relapsing remitting multiple sclerosis (MS) presented with episodes of what was perceived as a Dutch accent along with other neurologic symptoms that would resolve simultaneously. She was assessed by a speech therapist both during an episode and after complete recovery. Speech and MRI changes (showing deep white matter lesions in the corpus callosum, left pariental lobe and left frontal lobe) were consistent with previous reports of foreign accent syndrome.

CONCLUSIONS

This patient's episodes of foreign accent are thought to be due to her MS.
