RESUMEN
Antecedentes: la enfermedad de Alzheimer la describió, a principios del siglo XX, Alois Alzheimer. Representa la primara causa de demencia en el mundo. Se desconoce su etiología pero en su génesis participan factores genéticos ampliamente estudiados y ambientales menos definidos.
Objetivo: investigar en la bibliografía los aspectos históricos y moleculares de vanguardia de la enfermedad de Alzheimer.
Método: búsqueda en libros de historia de la medicina europea mediante el buscador Goggle. Para la revisión de biología molecular se examinaron los servidores de Medline y Ovid con palabras clave: “biología molecular” ,“enfermedad de Alzheimer”, “fisiopatología enfermedad de Alzheimer”, “patología enfermedad de Alzheimer”, “genética enfermedad de Alzheimer” de los años 1989 a 2009. La búsqueda se restringió a: revisiones, investigaciones sólidas e investigaciones de líderes en cada uno de los temas mencionados.
Resultados: entre más de 10,700 artículos se seleccionaron 49 que cumplieron con los criterios señalados.
Conclusiones: El depósito del A-beta amiloide es la piedra angular en la patogénesis de la enfermedad a la que le sigue una cascada de cambios intra y extraneuronales que culminan con la muerte celular.
