An epidemiological study of multiple sclerosis (MS) in the district of Halle, Halle-Neustadt and the area near the river Saale was carried out. We found 178 patients with a definite diagnosis in a total population of 396,529, corresponding to a prevalence of 44.9/100,000. The annual incidence rate was 2/100,000. When probable but not definitely diagnosed(More)
The diagnostic value of CSF oligoclonal IgG bands, intrathecal IgG synthesis, cytology and markers of myelin breakdown in the cerebro-spinal fluid were evaluated in multiple sclerosis. None of the various immunological alterations were unique to MS. The diagnosis depends therefore mainly on course and clinical symptoms, but can be supported by CSF analysis.
In our opinion there is no specific germ for multiple sclerosis. The pathogenic process is developed after a clinically "silent" period and results in a demyelinization process. Partially genetical aspects have to take into account for certain disease processes. Up to now both, the theory of infection as well as the neuroallergetic theory are of importance.
There are neither specific cell investigations nor immunological tests for the diagnosis of MS. Various immunological alterations occur in the course of the disease, but none is unique to MS. Accurate diagnosis remains confined to the clinical field. The diagnosis can be supported by CSF analysis. Laboratory examinations can help to determine the particular(More)
The cerebrospinal fluid of 69 patients with tumors of the brain and the spine was examined for total protein content, IgG concentration, IgG total protein quotient, and electrophoretic protein pattern. There is no specific finding in the case of the central nervous system. At best characteristic constellations may be established.
