Leucoencefalopatía multifocal progresiva - All Information

Nombres alternativos

LEMP

Definición:

Es un trastorno raro que ocasiona daño al material (mielina) que cubre y protege los nervios en la sustancia blanca del cerebro.

Causas, incidencia y factores de riesgo:

El virus JC (VJC) causa la leucoencefalopatía multifocal progresiva (LEMP). Hacia la edad de 10 años, la mayoría de las personas han estado infectadas, pero casi nunca provoca síntomas.

Sin embargo, cualquier persona con un sistema inmunitario debilitado está en mayor riesgo de desarrollar LEMP. Las causas para que se presente un sistema inmunitario debilitado abarcan:

  • SIDA (menos común ahora debido a los mejores tratamientos para esta enfermedad)
  • Ciertos medicamentos empleados para tratar la esclerosis múltiple, la artritis reumatoidea y enfermedades conexas
  • Leucemia y linfoma

Síntomas:

  • Dolores de cabeza
  • Pérdida de la coordinación, torpeza
  • Pérdida de la habilidad del lenguaje (afasia)
  • Pérdida de la memoria
  • Problemas de visión
  • Debilidad en piernas y brazos que empeora

Signos y exámenes:

Los exámenes pueden abarcar:

Tratamiento:

En personas con SIDA, el tratamiento para fortalecer el sistema inmunitario puede llevar a la recuperación de los síntomas de la leucoencefalopatía multifocal progresiva. No se ha demostrado la efectividad de otros tratamientos para esta enfermedad.

Expectativas (pronóstico):

La leucoencefalopatía multifocal progresiva es una afección potencialmente mortal. Hable con el médico acerca de las decisiones sobre los cuidados.
