Researchers are developing Alzheimer's blood test for early diagnosis
An early diagnosis is particularly important in Alzheimer's, since a cure is still not possible, but only a delay in the course of the disease can be achieved. Scientists from the Ruhr University Bochum (RUB), the University and the German Center for Neurodegenerative Diseases (DZNE) Göttingen have now developed a reliable, easy-to-use diagnostic option in the form of a blood test that they believe “potentially also enables early detection. "

According to the researchers, a major problem with Alzheimer's diagnosis is that “when the first clinical symptoms appear, massive irreversible damage to the brain is already present.” For this reason, medical diagnosis is often clearly too late. "If we want to have a drug in the future that can significantly slow down the further course of the disease, we urgently need blood tests that can detect Alzheimer's disease in its pre-essential phases," emphasizes Professor Dr. Klaus Gerwert, head of the chair for biophysics at RUB. Here, the researchers have obviously taken an important step in the development of such a blood test.

Alzheimer's diagnosis is usually too late
In view of the fact that Alzheimer's disease is often diagnosed too late, the RUB researchers, together with the scientists from the University of Göttingen and the DZNE, looked for ways to diagnose it early. They developed an Alzheimer's blood test based on an immunochemical process in the form of an infrared sensor, according to the RUB. The researchers explain the highly specific antibodies on its surface "fish biomarkers for Alzheimer's disease from the blood or nerve water that can be taken from the lower part of the back". The infrared sensor measures "whether the biomarkers have already changed pathologically, which can be the case more than 15 years before clinical symptoms appear." The test is thus also potentially suitable for the early detection of Alzheimer's.

Significance for future treatment options
The process of the newly developed Alzheimer's blood test was presented in the internationally renowned journal "Biophotonics" and the researchers published the clinical trial results in the specialist journal "Analytical Chemistry". They emphasize the importance of such a test procedure for the possible uses of medicines to be developed in the future. Only with a corresponding early diagnosis can the use of such drugs either prevent the onset of dementia or at least extend the period of time until it occurs, according to Professor Dr. med. Jens Wiltfang, director of the Clinic for Psychiatry and Psychotherapy at the University Medical Center Göttingen and coordinator of clinical research at the DZNE-Göttingen. (fp)
