La identificación de la enfermedad de Alzheimer antes que se manifieste, podría hipotéticamente permitir otro tipo de tratamiento con carácter incluso preventivo.
Investigadores de NYU School of Medicine han dado un paso más en este sentido. Mediante una nueva técnica que mide el volumen del cerebro fueron capaces de identificar individuos sanos que posteriormente desarrollarían un deterioro intelectual severo.
La metodología utiliza la RMN y una fórmula computarizada que se utilizó para medir el lóbulo témporo medial con un seguimiento durante 2 años y luego un seguimiento a los pacientes de 6 años. Encontraron que la pérdida de masa de esta región es notoriamente superior en aquellos individuos que desarrollarán problemas de memoria. La técnica presentó un valor predictivo positivo del 90% y similar valor predictivo negativo. Es decir, logra discernir entre quienes desarrollarán un problema de memoria y quienes no lo sufrirán.
El Profesor de Leon, responsable del proyecto, comentó que cree que esta técnica abre una nueva era en el diagnóstico precoz de la enfermedad de Alzheimer.
