Scientists from Spain under the command of Pedro Carmona discovered a new method of diagnosis Alzheimer   - A form of senile dementia . This method is based on the reaction leukocytes   to infrared light. Such data recently published in the journal Analitical & Bioanalitical Chemistry.

In the first test it was found that clusters squirrel at brain Peculiar to Alzheimer's disease, absorb a significant amount of infrared waves.

The method which has been described by the principal investigator, is non-invasive, rapid, and inexpensive. In addition, its high sensitivity makes it possible to capture even small differences between mild and moderate clinical stage of the disease. This is due to the increase in concentration of a specific protein in the body in the development of Alzheimer's disease.

In the second stage of the study involved 20 healthy people and 50 patients with Alzheimer's disease. Using spectroscopy Scientists from Madrid compared radiation in patients with different forms of the disease as well as the results of studies in healthy individuals.

The result revealed an appreciable difference leukocytes of healthy people in the emission of infrared light from similar cells from patients with dementia. And the more the disease has been developed, the greater were the differences in the test results.

How to evaluate a new method of testing the authors, it will soon be able to replace biochemical blood   the huge number biomarkers Which is currently used for the diagnosis of Alzheimer's disease.
