The first Alzheimer's disease AI screening applet, the elderly can self -test the risk of illness in ten minutes

On August 31, the China Elderly Health Association Alzheimer's Disease Branch (ADC) and Alibabada Institute launched the nation's first Alzheimer's AI screening applet. It has passed medical verification and can be used on mobile phones to self -help self -help mobile phones. It only takes about ten minutes to complete the screening. Experts expressed their hope to make up for the lack of grass -roots medical resources and promote the large -scale public welfare screening of Alzheimer's disease.

Alzheimer's disease has become a healthy killer for the elderly in China. A study in 2020 of the international medical magazine "Liuye Knife" showed that among the elderly 60 and above, there were 9.83 million patients with Alzheimer's disease. Because brain injury is irreversible, Alzheimer's disease is currently difficult to cure, but after discovery in advance, you can delay the process by intervention. Due to large -scale screening, a large number of medical resources are required, and many regions have limited conditions, especially at the grassroots and remote areas, far from 80%of the screening rates advocated by the National Health Commission.

On the occasion of the World Alzheimer's Cycles (September), the ADC and Aridham launched the AI ​​screening applet to reduce the screening threshold through technological innovation. The reporter's experience found that the mobile phone Alipay was turned on, searching for "ADC dementia screening", and simply filling in the information to start screening. Screening needs to complete the steps of voice answers, draw clocks, etc., about ten minutes. AI can automatically analyze the situation, and then artificially reviewed by experts. If the screening results are high risk, the system will also remind the hospital for further clinical diagnosis.

Example of screening results

"This is the first domestic AI screening applet in Alzheimer's disease. We have already done thousands of tests in the early stage. After passing medical verification, the sensitivity and specificity have exceeded 80%." ADC deputy chairman and secretary Sun Yongan, chief physician of the first hospital of Peking University, introduced that AI screening combines classic clinical cognitive screening tables and the latest artificial intelligence technology, which can quickly and effectively evaluate the risk of Alzheimer's disease. Taking the classic painting clock test as an example, it seems simple, but in fact, it tests the elderly's cognitive ability, especially the space positioning ability.

Sun Yongan said that offline screening costs time and labor, and the elderly need to go to the hospital in person, or rely on professional assistance, and now the mobile phone operation is easy and easy. He hopes that this tool will push away in the grassroots and remote areas where medical resources lacks and solve large -scale screening problems.

Xu Guohai, a senior algorithm engineer in Alida, introduced that Alzheimer's disease AI screening applies the industry's cutting -edge multi -mode AI technology, and uses voice semantics to evaluate the elderly's voice answers and avoid the deviation of the accent. They also focused on the problem of AI identifying the hand -painted clock of the elderly. Due to the extremely diverse hand -drawn of the elderly, it involved a variety of relative relationships such as contours, numbers, and pointers. Experts that need to be experienced to accurately judge. The Dharma Academy AI not only learned the results of expert judgment, but also learned the basis and knowledge of expert judgment, which formed an explanation of AI. Not only did they know it, but they must also know why they successfully transformed expert knowledge into AI capabilities.

All kinds of hand -painted clocks

According to reports, since 2021, the Dharma Academy began to study Alzheimer's AI screening, and the team of the School of Public Health of Zhejiang University conducted offline screening in Hangzhou. Through medical professional assessment. Furthermore this year, Dharma Institute and ADC jointly developed AI screening mini -programs, which manually assist in screening to online self -service screening from offline.

Experts remind: Screening is not equal to clinical diagnosis, please go to the doctor in time.
