From Alzheimer's Daily News:

(Source: Springer Select) - Spanish researchers, led by Pedro Carmona from the Instituto de Estructura de la Materia, have uncovered a new promising way to diagnose Alzheimer's disease more accurately. Their technique, which is non-invasive, fast and low-cost, measures how much infrared radiation is either emitted or absorbed by white blood cells. Because of its high sensitivity, this method is able to distinguish between the different clinical stages of disease development, thereby allowing reliable diagnosis of both mild and moderate stages of the disease.

The researchers used two-dimensional infrared spectroscopy to measure and compare the infrared radiation emitted or absorbed by white blood cells of healthy controls, versus those of patients with mild, moderate and severe Alzheimer's disease. A total of 50 patients with Alzheimer's and 20 healthy controls took part in the study.

The authors found significant differences in the range of infrared wavelengths displayed between subjects, which were attributable to the different stages of formation of amyloid-B structures in the blood cells. The results showed that, with this method, healthy controls could be distinguished from mild and moderate sufferers of Alzheimer's disease. The method is being explored as a tool for early diagnosis.
