[Epidemiologic study on the etiopathogenesis of multiple sclerosis].

A computer-aided evaluation of those affected with multiple sclerosis (n = 90) with regard to the actually discussed hypothesis on the aetiology of this disease results in 10 significant signs. These signs in their majority support the combined hypothesis of a disturbed regulation of infection and immunity. Frequently, as early as in childhood and youth the upper airways are affected, and this is coupled with a severe course of the disease. The incidence also shows familially and territorially frequent occurrences.
