Alzheimer’s blood test could be used to screen even before symptoms: Study

A new study suggests that testing blood for a protein called p-tau217 can accurately screen for Alzheimer's disease before symptoms appear.
The blood test was found to be up to 96% accurate in identifying elevated levels of beta amyloid and up to 97% accurate in identifying tau.
This blood test could reduce the need for costly and invasive brain scans or spinal taps, providing a faster and more accessible method of diagnosing Alzheimer's.

Alexandra Ferguson (CNN) — Un nuevo estudio sugiere que un análisis de sangre para detectar un tipo de proteína denominada tau fosforilada o p-tau podría servir para detectar la enfermedad de Alzheimer con “gran precisión”, incluso antes de que se manifiesten los síntomas. En el estudio se analizó la sangre para detectar un biomarcador clave del Alzheimer llamado p-tau217, que aumenta al mismo tiempo que otras proteínas dañinas (beta amiloide y …
