简单血液测试可以预测阿尔茨海默症的发病时间
科学家们开发了一种血液测试，可以预测阿尔茨海默症的症状何时会出现。通过测量一种叫做p-tau217的蛋白质，模型可以预测症状的开始时间大约在三到四年内。这一蛋白质反映了大脑中阿米洛伊和tau的沉积，远远早于记忆丧失的出现。这一突破可…

ScienceDaily Simple blood test can forecast Alzheimer’s years before memory loss Scientists have created a blood test that can estimate when Alzheimer’s symptoms are likely to begin. By measuring a protein called p-tau217, the model predicts symptom onset within roughly three to four years. The protein mirrors the silent buildup of amyloid…
