[Dyslexia of digits and numbers in multiple sclerosis].

In a 32-year-old man with remitting-progressive multiple sclerosis a right-side hemiparesis and alexia of digits of numbers developed during an exacerbation. While reading aloud the patient changed digits, left them out or transposed. No changes were observed in reading of letters, words and no agraphia was present. Alexia persisted for about one month. The location of alexia in the occipital lobe and its association pathways with the left parietal lobe are discussed.
