[Clinical picture of transitional forms between multiple and diffuse sclerosis].

A female patient is described in whom the disease clinical picture, as regards the localization of the multiple lesions in the nervous system (optic nerves, pyramid and cerebellar paths), the undulatory course of the process, and the characteristic manifestations (epileptic seizures, intellect derangement) combined symptoms of both disseminated and diffuse sclerosis. This allowed the author to think that this patient had a transitional form between the disseminated and diffuse sclerosis.
