Análisis de sangre p-tau217 predice riesgo de Alzheimer hasta diez años

Análisis de sangre p-tau217 predice riesgo de Alzheimer hasta diez años

Según AP News, investigadores informaron que niveles elevados de la proteína p-tau217 en sangre predicen una probabilidad del 38 % de deterioro cognitivo en cinco años y del 78 % en diez años en adultos mayores sin síntomas. El New York Post replicó esas cifras de riesgo. Neuroscience News señaló que la asociación se mantiene independiente de los hallazgos de PET de amiloide y del genotipo APOE4, lo que indica un valor predictivo autónomo del biomarcador.

ABC News informó que expertos advierten que la prueba aún no está lista para su uso clínico rutinario. Posteriormente, Fox News y AOL. com reiteraron las conclusiones del estudio liderado por Harvard, subrayando el riesgo elevado y el potencial del análisis sanguíneo, aunque también resaltaron sus limitaciones actuales.
