Scientists have developed a new genetic test that could predict the age you're likely to develop Alzheimer's disease.

科学家开发了一种基因测试新方法,可预测一个人可能罹患上阿尔茨海默症的年龄。

How does it work?

如何进行检测?

The test, which could use DNA from blood or saliva, was developed using genetic information collected from more than 70,000 people with Alzheimer's.

从血液或唾液提取DNA的检测技术,是采用阿尔茨海默症患者70,000多名基因信息开发而成的。

Previous genetic testing for Alzheimer's has largely relied on looking for defects in a just one gene called APOE, which is known to raise the risk of the disease. But this new method has the ability to check for deficiencies in 26 different genes – all of which were found in participating patients – in order to calculate an individual's 'hazard score'.

阿尔茨海默氏病基因检测过去一直是寻找称为APOE基因变异。大家知道,这种基因会增加阿尔茨海默氏病患病风险。但是,现在技术方法能检测26个不同基因——在阿尔茨海默病患者中存在这些基因变异。该项技术就是通过26个不同基因变异检测给出“危险评分”预测个人患病风险。
