Scientists are therefore still searching for an accurate predictive test that is cheaper, quicker, and less invasive than PET scans or lumbar punctures. This year, two small studies of blood tests seemed to predict Alzheimer’s 1-3 years before it occurred, but the tests are complicated and require the measurement of ten or more substances.
因此，科学家仍在寻找比PET扫描或腰椎穿刺更廉价、更快速、更加不痛苦的准确预测测试方法。今年，两项小型血液测试研究似乎可以在阿尔茨海默症出现前1—3年作出预测，但测试很复杂，需要测量十种或以上物质。
