Question:
What are the incidence and prevalence rates of ALS?
La epidemiología de la esclerosis lateral amiotrófica
En los últimos tres decenios, ELA ha desarrollado una distribución igual en todos los países importantes del mundo. La enfermedad tiene una tasa de incidencia de 2 por cada 100.000 personas. La aparición de la ELA es mayor en hombres que en mujeres, y 5.600 nuevos casos cada año en los Estados Unidos. Sin embargo, la tasa de prevalencia entre hombres y mujeres es casi idéntico, a medida que envejecemos. Se estima la tasa de prevalencia de la ELA en los Estados Unidos es de 5 por 100.000 de la población total. Esto significaría que si se habían reunido en una multitud de 100.000 personas, al menos cinco de estas personas serían diagnosticadas con ELA dentro de esta población específica, y durante este tiempo en particular.
El número de pacientes diagnosticados con ELA es alta en los Estados Unidos e Inglaterra en comparación con otros grandes países con la misma población. Países como Italia y Polonia fueron descubiertos a tener menores tasas de incidencia que en otros países como los Estados Unidos.
Sin embargo, durante la primera mitad de 1990, hubo una serie de agrupaciones casos diagnosticados en Japón, Micronesia, e Indonesia, con una tasa de incidencia local, al menos cincuenta veces más alta que la tasa de incidencia en todo el mundo.
Por lo general, las personas diagnosticadas con ELA son 40-70 años de edad, con una esperanza de vida media de 2-5 años. Veinte por ciento sobrevive por cinco años, y 10 por ciento de los pacientes con ELA va a vivir por lo menos diez años.
