Clinical Features of the Spinal Form of Multiple Sclerosis

Out of a data pool of 1271 patients with Multiple Sclerosis (MS) a total of 109 cases are selected having a sole spinal symptomatology throughout the course of the disease. This group differs in three particular features from the non-spinal forms of MS: In this group there is a higher percentage of females, the age at onset of the disease is higher, and the course of the disease is more often chronic progressive from the beginning. After the mean duration of 11 years, the spinal and the non-spinal cases show the same grade of disability. The ability to work is slightly better for spinal cases; office workers are able to keep their jobs longer after the onset to the disease than patients with any other occupation. The spinal form of MS is discussed in respect to its relationship to the classical form of MS and as a differential diagnosis to other spinal processes.
