[Subacute sclerosing panencephalitis. Report of 31 cases (author's transl)].

We present 31 cases of subacute sclerosing panecephalitis from the epidemiologic, clinical, electroencephalographic, laboratory and anatomopatological point of view. Psychical disorders (51,59%) and generalized convulsive fits (19,45%) stand out as a first cause of consultation. A high visual hallucinatory incidence (35,48%) was observed. Repeated complexes were of great value for the early diagnosis as well as the high titers of measles-virus antibody in the serum and cerebrospinal fluid for the diagnosis corroboration.
