A blood test predicts the possibility of Alzheimer's disease in the elderly In their study, this research team examined the blood samples of more than 1,000 cognitively healthy elderly people as well as people with cognitive impairment. During this research, they found that only those who had both amyloid markers (signs of brain pathology implicated in Alzheimer's) and their blood markers, abnormal activation or reactivity of astrocytes, were likely to develop symptomatic Alzheimer's disease in the future. or star-shaped cells. This finding is very important for the development of effective drugs to stop the progression of this disease. Tharick Pascoal, PhD and associate professor of psychiatry and neurology at the University of Pittsburgh, explained the results and implications of this research and stated: " Our studies show that the best way to screen people who are most at risk of developing Alzheimer's disease is to test for the presence of brain amyloidosis along with a blood test for markers of astrocytes or stellate cells. » This research has focused on astrocytes as the main agents in the progression of Alzheimer's disease, to challenge the notion that amyloids are sufficient to initiate Alzheimer's disease. more at Tehranlab
