[Cerebrospinal fluid diagnosis of multiple sclerosis]

Abstract

Starting from the knowledge accumulated with respect to the etiopathogenesis and the components of immunoreaction a minimal to maximal program by steps has been developed for the cerebrospinal fluid (CSF) in multiple sclerosis (MS). It is based on fundamental methods (I), special supplementary methods (II), and relatively specific immunological methods (III). For MS five possible conditions of the CSF could be determined from alterations of cells and variations in protein: a (1) typically complete and (2.) typically incomplete immunoreactive encephalomyelitic (encephalitic) syndrome, a (3.) nonspecific CSF-syndrome of low degree and less typical character (in the sense of an acute or subacute irritation syndrome) an (4.) atypical syndrome of a considerable degree, and a (5.) normal condition of the cerebrospinal fluid. The significance of immunoreactive cerebrospinal fluid syndromes to the diagnostic criteria of multiple sclerosis as well as further relatively disease-specific methods (such as the MEM test and MSF assay) of determining cellular immunity, are discussed.
