Prevalence of multiple sclerosis in Valladolid, northern Spain Tola Arribas, Miguel Ángel Yugueros Fernández, María Isabel Fernández Buey, Nieves Fernández Herranz, Rosario Esclerósis múltiple Producción Científica The aim of this study was to ascertain the prevalence of multiple sclerosis (MS) in a northern Spanish region and to compare it with that from the most recent epidemiological studies in the country. MS prevalence was studied for a period of 2 years using multiple sources of information in the province of Valladolid, with a sample comprising a total population of 92,632. Patients were classified according to the Poser criteria. The crude prevalence of definite and probable MS was 58.3 per 100,000 (95% confidence interval: 43.7–75.7). The same methods have been used in ascertaining similar prevalence rates in Vélez-Málaga, Osona, and Gijón and a slightly lower rate in Teruel. Our survey confirms Spain as a high-risk area for MS, with prevalence rates over 50 per 100,000 2015-02-04T08:36:14Z 2015-02-04T08:36:14Z 1999 info:eu-repo/semantics/article Journal of Neurology, (1999), vol.246, n. 3 p.170-174 0340-5354 http://uvadoc.uva.es/handle/10324/8127 10.1007/s004150050329 170 3 174 Journal of Neurology 246 eng Attribution-NonCommercial-NoDerivatives 4.0 International info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0/ application/pdf Steinkopff Verlag https://uvadoc.uva.es/bitstream/10324/8127/6/Tola%202-PD%20185.pdf.jpg Hispana TEXT http://creativecommons.org/licenses/by-nc-nd/4.0/ UVaDOC.
