Vieron que, en algunos casos, el riesgo de demencia bajaba notablemente, aunque en el conjunto general antes no se había encontrado ese efecto.","fuente":"sciencedaily","fuenteNombre":"ScienceDaily","color":"#0b6ea8","autor":"","url":"https://www.sciencedaily.com/releases/2026/10/261024222026.htm","imagen":"/hoy/portada/7b388a64c95b0e72","tema":"salud","subtemas":["demencia","aspirina","genetica","prevencion","adultos mayores"],"entidades":["Universidad de Yale"],"formato":"dato","entretenimiento":false,"pubTs":"2026-10-25T10:21:48.000Z","indexTs":"2026-10-25T12:37:35.110Z","hash":"de43200a04c686473ca05440647789d34a720a5018b30f7053b19486ad73eda0","tsa":{"time":"Oct 25 12:38:11 2026 GMT","provider":"freetsa.org","sobre":"sello"},"stats":{"views":0,"likes":0,"clicks":0,"dwell":0},"tipo":"motor","registro":"hallazgo","porQueImporta":"El dato clave es que el beneficio aparece solo en personas con cierta genética, por eso estudios anteriores no lo detectaban. Para quien tiene más de 60 años, la pregunta deja de ser si la aspirina sirve y pasa a ser quién la necesita. Eso no alcanza para recomendarla sin consultar: el estudio es observacional y el sangrado sigue siendo un riesgo real.","quienFirma":"Universidad de Yale","confianza":"revisado","consulta":{"pregunta":"¿Tomarías aspirina para prevenir demencia si tu genética lo justificara?"}},"sello":{"hash":"de43200a04c686473ca05440647789d34a720a5018b30f7053b19486ad73eda0","sello":"690d01c75c7307d8ade679dc9c2b36342843817a5e84bdbd0fee2087235b840a","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6583362,"aleatorio":"9d20ff7d43c8e3fe5e9508c31365e99bf7c6ed51dcd7601d9e105871c644dc16","tiempo":"2026-10-25T12:38:00.000Z"},"nist":{"cadena":2,"pulso":1998874,"salida":"6E2DD3FF27CDB528959E4008BB8061B458D149C4A4DB74FCB38F4716BC4B5D5BB755F51E5669DEC372601B493BF762D1547A6CC1F014FB1ED5988F3248B6D729","tiempo":"2026-10-25T12:37:00.000Z"},"noAntes":"2026-10-25T12:38:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 25 12:38:11 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Low-dose aspirin linked to 70% lower dementia risk, but there's a catch","descripcion":"A common, inexpensive medication could hold an unexpected clue to preventing dementia. Researchers found that older adults with a specific genetic profile had a 70% lower relative risk of dementia when taking low-dose aspirin, even though previous studies found no overall protective effect. The discovery suggests that genetics could help explain why some people benefit while others do not.","pubDate":"Sun, 25 Oct 2026 06:21:48 EDT","url":"https://www.sciencedaily.com/releases/2026/10/261024222026.htm"},"indexado":"2026-10-25T12:37:35.110Z"}}
