title: Multiple sclerosis in Europe.
abstract: At a symposium held in conjunction with the 13th World Congress of Neurology, epidemiological data were presented from 23 European countries. In addition to the confirmation of the well-known north-south gradient, new details emerged on the high-prevalence areas of the British Isles and Scandinavia and on high-prevalence areas in some of the eastern and Mediterranean countries requiring more intensive exploration and confirmation. It became evident that higher prevalences existed in some places in Southern Europe previously thought to be regions of very low frequency. Limitations in the evaluation and comparison of data presented were obvious in view of differences in concepts, techniques and the intensity of surveys carried out. There was general agreement that this first collaborative attempt to map the frequency of multiple sclerosis in Europe should be followed up by standardized procedures and more cooperation in epidemiological surveys.
