Este estudio sugiere que una parte de esos efectos atribuidos al trastorno se explica por factores que la familia comparte, como el ambiente en el que crece el chico. Para padres y docentes, esto cambia la pregunta: no alcanza con diagnosticar, hay que mirar también el entorno. El trabajo usa datos genéticos y compara hermanos, pero las asociaciones no prueban por sí solas cuánto del efecto es genético ni cuánto es causal.","quienFirma":"Universidad de Bristol y colaboradores (preprint; institución principal probable)","confianza":"preprint","consulta":null},"sello":{"hash":"00aecff13be04828ab802b6edf079e6ff3dbac828c48cfb5c181617325ebb6f0","sello":"f8a67e2d4216d16ca1e45103ad6e462d0bd7264bf60c8e37ebdfe8dd8a61c614","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6589557,"aleatorio":"074102cb3486d8030e85bccc146ee3d40bd144f9cae3dc815e4783f75ca0035b","tiempo":"2026-10-27T16:15:30.000Z"},"nist":{"cadena":2,"pulso":2001772,"salida":"0E703280D2ECB99CF237148891BE4B05125CA4A9FA93BA99C93DE108693398FC1C1436A917C2E942D3FD99D4FACCDDC40E70589522F4EEDE9B18514294B0BD55","tiempo":"2026-10-27T12:55:00.000Z"},"noAntes":"2026-10-27T16:15:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 27 16:15:55 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Familial factors inflate the estimated effects of genetic liability to ADHD on behavioural outcomes","descripcion":"Background: People with ADHD have worse health, behavioural and social outcomes, widely interpreted as evidence that ADHD causes these harms, justifying early identification and treatment. But ADHD clusters in families, and conventional studies cannot separate the effect of a person's own ADHD from the family environment in which it arises. We used a family-based genetic design to distinguish the two. Methods: We used up to 22 genome-wide significant variants associated with ADHD (38,691 cases, 186,843 controls) to estimate effects of genetic liability to ADHD on 16 health and behavioural outcomes. We compared population-based estimates with family-based estimates from within-sibship analyse","pubDate":"2026-10-27","url":"https://www.medrxiv.org/content/10.64898/2026.10.27.26366008v1?rss=1"},"indexado":"2026-10-27T16:14:26.625Z"}}
