A blood test aimed at identifying the first signs of Alzheimer’s was developed by a team of Australian and Japanese scientists.
We had already written about a blood test to identify the risk of Alzheimer’s. The test tries to identify the presence of Amyloid Beta, a toxic protein found in people with Alzheimer’s. The test was performed on 373 Japanese and Australian patients. Other teams, (like that of the  Washington University School of Medicine in St. Louis.) worked on similar tests with good results.
An abnormal number of proteins such as amyloid beta and tau appear to be an important factor in concomitance with the presence of Alzhemier. This type of protein begins to conglomerate long before the symptoms of the disease (such as memory loss) occur (even the accumulation of these proteins cpuò begin twenty or thirty years before the onset of symptoms).
It is not yet clear how exactly Alzheimer’s starts and there is no specific cure, but early detection can lead to a change in the patient’s lifestyle, also intensifying the checkup, to reduce the impact of the disease.
