The risk of Alzheimer's disease and mild cognitive impairment in the future can be estimated by measuring the level of specific proteins in the blood, a new Japanese study has found The team believes that this will help to detect such diseases as early as possible and take interventions Alzheimer's disease is believed to be related to the excessive accumulation of β - amyloid protein in the brain At the beginning of 20 years before the onset of the disease, β - amyloid protein will gradually accumulate in the brain β - amyloid protein can cause damage to nerve cells and affect the function of synapses which are responsible for memory and cognition Human beings have the mechanism of keeping β - amyloid from accumulating in healthy state Researchers from the University of Tsukuba in Japan found that complement protein, apolipoprotein and thyroxin play an important role in the process of excreting β - amyloid protein and curbing its toxicity After analyzing the data of cognitive disease survey, the research team found that the content of these three proteins in the blood of the elderly with mild cognitive impairment and dementia was gradually reduced compared with the elderly without disease The team's experiment confirmed that taking a few milliliters of blood to test the content of these three proteins can determine the cognitive health level of the tested person and the future risk of disease with an accuracy of about 80% (reporter LAN Jianzhong)
