Aphasia in multiple sclerosis.

In a 17-year-old woman, motor aphasia developed during her second bout of multiple sclerosis, characterized by absent spontaneous speech, paraphasias in naming and repetition, and marked orofacial apraxia, with relative preservation of written language and intact auditory comprehension. A mild right hemiparesis was associated. Bilateral cerebral lesions were demonstrated on a computerized tomographic brain scan. The aphasia remitted over 1 month.
