[Analysis of 228 cases of multiple sclerosis (author's transl)].

: The authors report some observations about 228 cases of multiple sclerosis with secure diagnosis subdivided in severe (34,6 %), common (29,8 %) and benign after the tenth year of illness (35,6 %). These observations are in agreement with classical statistic reports concerning the natural disease history : higher female incidence (64 %), average age at onset about 29,5 years, 4 main first signs (ocular [42,5 %], motor [41,5 %], ataxia [36,3 %], sensory [35 %] and remitting course [82,5 %]). Follow up study of 81 "benign" forms after the tenth year of the disease allows us to look at the freqwuency of "secondarily worsening" forms (25,7 %) and "benign remaining" ones until the twentieth year (10,1 %).
