Multiple sclerosis (MS) has recently been classified according to its clinical course. Despite relapses and remissions, its course is invariably progressive, and the observed progression from the remitting-relapsing to the secondary progressive form represents the accumulation of permanent damage to the nervous system. Discussions of the nomenclatural position of Schilder's, Marburg's, and Baló's diseases, ignore the fact that the unique, pathognomonic, sharp-edged plaque of MS, is also the pathologic end-result in the three variants. ⋯ The genetic determinant was also crucial in the marmoset in which EAE uniquely resulted in a chronic relapsing-remitting (RR) disease characterized by the classic sharp-edged lesions of MS. The question 'ADEM: distinct disease or part of the MS spectrum?' can be answered with a resounding no. A new classification is proposed separating the different forms of MS from the various types of DEM.

Biography Historical ArticleDiagnostic criteria for multiple sclerosis: an historical review.
Starting with Charcot, diagnostic criteria for multiple sclerosis (MS) have evolved to reflect advances in our understanding of the disease and the development of new diagnostic techniques, and from purely clinical considerations to increasing dependency upon imaging of the central nervous system. The MS diagnostic process was revolutionized by the 1981 introduction of magnetic resonance imaging (MRI), but the increasing reliance upon this technique has led to a surge in erroneous diagnoses, mostly because of the failure to distinguish between MS and disseminated encephalomyelitis (DEM), as well as mounting disregard for the data obtained from the traditional history and physical examination. ⋯ The choice will have to be made by the neurological community between basing the diagnosis of MS on the MRI alone, or to use it as one aspect of a comprehensive clinical diagnostic algorithm. There will never be a substitute for the experienced and astute clinician's 'feel' for the patient.
