Incidencia de la esclerosis múltiple en el área sanitaria de Alcoi. Estudio de 12 años (19861997)

This is the most prolonged study of the incidence of multiple sclerosis carried out in Spain. The figures found for incidence are in contrast to those found in previous years for prevalence and incidence. Analysis of the data suggests that the incidence of multiple sclerosis in the Alcoi district has changed and has increased since the second half of the 1980s.
