Abstract
El Síndrome de Piernas Inquietas (SPI) es un trastorno sensitivo-motor que se caracteriza por la presencia de una necesidad de mover las piernas, acompañada o no por disestesias en las mimas, que aparece durante el reposo, con perfil circadiano vespertino/ nocturno y mejoría al mover las piernas. Su prevalencia es del 7,2-11,5%, mostrando un predominio femenino y tendencia a aumentar con la edad. Su fisiopatología es compleja, habiéndose demostrado la presencia de un estado hiperdopaminérgico e hiperglutamatérgico, favorecido por alteraciones en el metabolismo cerebral del hierro. Con frecuencia los pacientes presentan ferropenia sistémica, aunque los síntomas no se correlacionan con los niveles séricos de ferritina sino con la biodisponibilidad cerebral de hierro. Las donaciones reiteradas de sangre favorecen la ferropenia, por lo que podrían suponer un aumento del riesgo de SPI...
Restless Legs Syndrome (RLS) is a sensorimotor disorder primarily involving legs discomfort and motor restlessness, worsening of symptoms during evening and night, and relief with activity. The prevalence of RLS is 7,2 -11,5%, with a female predominance, and a trend to increase with age. RLS pathophysiology is complex. The existence of a hyperdomanergic and hyperglutamatergic status has been proven; there is probably an underlying brain iron metabolism disorder. Patients usually show systemic iron deficiency, although RLS symptoms do not show correlation with ferritin blood levels but with the availability of brain iron. Regular blood donations promote iron deficiency, possibly increasing the risk of RLS...
