Researchers develop Alzheimer's disease diagnostic device

Medical Network October 26, South Korea's Future Creation Science Department said on the 23rd that a research team composed of Korean medical experts has developed a device that can analyze the level of beta-amyloid in the brain, allowing Alzheimer's disease (again The diagnosis of Alzheimer's disease is greatly accelerated.

Researchers have previously found that a large accumulation of beta-amyloid in the brain is a direct cause of Alzheimer's disease. In fact, all brain cells produce beta-amyloid, but this harmful protein only accumulates in the brains of patients with this disease .

Yonhap News Agency quoted officials from the Ministry of Science and Technology in the future. Under the leadership of Seoul University researcher Wen Renxi, the team developed an early diagnostic device for Alzheimer's disease. This device detects this condition in the early stages of the disease and even in the high-risk period before the disease by detecting the level of accumulation of beta-amyloid in human blood samples.

The clinical symptoms of Alzheimer's disease manifest as cognitive, memory, and language dysfunction. Because there is no effective cure, existing drugs can only relieve symptoms and slow progression. At present, the clinical diagnosis of this disease relies on magnetic resonance imaging scanning and other means, which is costly and time consuming, and can often be diagnosed when the patient enters the stage of development of the disease.

Wen Renxi said that this new technology is different from the existing diagnostic methods. "That is because we can diagnose the disease at a very early stage without any symptoms, and the accuracy rate is over 90%."
