Spaniards scientists have developed a new blood test can identify early stages of Alzheimer's disease. Under this test could show scientists under the red lights in white blood cells to seventy people, which identified the levels of a protein called beta amyloid-related disease, which affects the brain.
And scientists in particular are keen to develop this blood test to detect the disease early, because this can be affected by the intake of drugs which have proven to slow the progression of the disease and existing.
It is noteworthy that the techniques currently approved for control of early Alzheimer's disease include the withdrawal of small amounts of cerebrospinal fluid in the spine. But that lumbar puncture is often painful, which means that it is not practical as a way to examine a large number of people.
Researchers have discovered now that the remnants of amyloid beta protein can be detected in the blood.
Using a method called "infrared spectroscopy two-dimensional" scientists can measure and compare the wavelength of light emitted from the white blood cells to fifty people living with different stages of Alzheimer's disease and twenty healthy volunteers.
The researchers found a strong correlation between the type of light emitted from the cells and the severity of Alzheimer's. This was due to the different stages of the remains of a so-called amyloid beta-peptide (a compound consisting of two or more amino acids).
This is not the first blood test for Alzheimer's is a possible consideration. There are British researchers at Kings College London are currently working on the examination depends on the levels of a protein called Klstran, while looking scientists in America and examine other ways of Finland.
Said Dr. Laura Phipps of the Center for Research of Alzheimer's in Britain that the technical Spanish can carry useful information to detect the disease, but warned that this work is still in its infancy, and it takes many years to develop a diagnostic test that can be used in clinics, and it needs more Search to find out the possibility of this method.
She said Dr Anne Corbett of the Alzheimer's Association that the British do not know whether a change in proteins is the cause of the disease, or view, or is it possible to detect the disease before symptoms develop.
