Este trabajo aporta datos de África Central, donde todavía hay poca investigación sobre envejecimiento cognitivo. Para un lector argentino, la lección es que una herramienta que funciona en un grupo no necesariamente sirve en otro, y que la diversidad en la investigación importa para que los diagnósticos sean justos. Es un estudio transversal, con datos de un momento puntual, así que no permite decir qué causa qué.","quienFirma":"medRxiv (estudio EVCD RDC, Kinshasa)","confianza":"preprint","consulta":null},"sello":{"hash":"129f7d14d2bffa7e317e8eb55d3b7f9b27369b2834dc7e4c9121b8a64751c236","sello":"a796db2af4ceef5acb12a99f984856da51bf27d0df3b3faf0c73f14c105d70ec","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6580831,"aleatorio":"262643bbe341b8c3807432fb78ff291db2ade17b0e7e9f0105cbe7bb43b6e923","tiempo":"2026-10-24T15:32:30.000Z"},"nist":{"cadena":2,"pulso":1997609,"salida":"DD72F75AE5AD3DE3C93AB6F4DBB917D4C339BAC6973F1AD21757A9E79F6A134FB9F3A46FE525113B7D5F609A7DDE1E3D6D7928B022174443C86BCA0D86345053","tiempo":"2026-10-24T15:32:00.000Z"},"noAntes":"2026-10-24T15:32:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 24 15:33:01 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Plasma Proteomic Correlates of Cognitive Function in Older Adults From Central Africa","descripcion":"Importance: Blood based proteomic biomarkers may support scalable dementia research, but their associations with cognitive phenotype remain poorly characterized in sub Saharan African populations. Objective: To examine associations between selected plasma proteins and multidomain cognitive performance in older adults in the Democratic Republic of Congo.

Setting: Community based prospective cohort in Kinshasa, Democratic Republic of Congo.
