[Explanation] Recently, Jia Jianping's team from Xuanwu Hospital of Capital Medical University published a paper and discovered for the first time biomarkers that can predict Alzheimer's disease 5-7 years in advance, with an accuracy rate of 87%-89%. On August 14, a reporter from China News Agency interviewed Jia Longfei, the first author of the paper.
[Explanation] Jia Longfei introduced that Alzheimer's disease is commonly referred to as senile dementia. There is currently no effective treatment and diagnosis is not easy.

Usually, in our clinic, the more certain diagnostic marker that everyone can accept is cerebrospinal fluid, but this requires a lumbar puncture. But this examination is traumatic, and sometimes there will be some pain to a certain extent, pain or some problems later. So our current research is that we can draw blood normally, and then we go to the later stage of examination, and then we can provide a diagnosis before the symptoms of AD (Alzheimer's disease) appear.
[Explanation] Jia Longfei said that the Alzheimer's disease biomarkers discovered this time exist in venous blood and can be easily detected.

We take blood routinely, for example, take a blood routine, just like this.
[Explanation] Jia Longfei told reporters that the pathological changes related to Alzheimer's disease have occurred before symptoms appear. Therefore, by detecting biomarkers, the occurrence of Alzheimer's disease can be predicted several years in advance, and the disease can be evaluated. Effective prevention.

Our method is that we can detect some traces of pathological changes before the symptoms appear, and then we can predict in advance that the disease may be acquired. And its great significance is that at this time when there is no effective medicine that can cure AD, if we can find it in advance, we can take some measures. For example, the control of some risk factors and the control of some living habits can reduce the incidence of AD. This is on the one hand, on the other hand, can we use some medications to treat patients without symptoms? Give it to the patient at that time, so that his disease can be controlled?
[Explanation] Jia Longfei said that in the next step, they plan to further optimize testing methods and reduce costs so that preventive screening for Alzheimer's disease will benefit the general public as soon as possible.
