INFRARED ANALYSIS OF PERIPHERAL BLOOD FRACTIONS OBTAINED TO INDICATE COGNITIVE DEVELOPMENT ASSOCIATED WITH ALZHEIMER'S DISEASE

摘要

The invention relates to a method for transmission infrared spectroscopy for determining the degree of global cognitive deterioration associated with Alzheimer's disease, on the basis of analysis of the 3100-1300 cm-1 region of the infrared spectrum of a previously obtained and fractionated blood sample. The fractionated blood sample to be analyzed is preferably a leucocyte fraction. Likewise, the invention relates to the use of said method to obtain an indication of the status of the Alzheimer's disease and/or an indication of the degree of cognitive deterioration associated with said disease.
