Multiple sclerosis in Chile

Acta Neurol Scand. 1992 Jan;85(1):1-4. doi: 10.1111/j.1600-0404.1992.tb03986.x.


So far as we know this series of 68 cases is one of the first clinical accounts of multiple sclerosis in South America. Average age of onset was 30.7 years and female:male ratio was 2:1. The most frequent initial symptom was motor impairment and less frequent was visual loss. Most affected site of involvement in established cases was the optic nerve. There were no familial cases. The severity of the disease in Chile proved to be the same as elsewhere. No characteristic clinical pattern peculiar to the region emerged.
