A pilot study suggests infrared analysis of white blood cells is a promising strategy for diagnosis of Alzheimer's disease. Spanish researchers, led by Pedro Carmona from the Instituto de Estructura de la Materia in Madrid, have uncovered a new promising way to diagnose Alzheimer's disease more accurately.
