A group of Georgetown University researchers, led by Howard Federoff, has developed a blood test that can diagnose Alzheimer's disease three years before it occurs. The accuracy of the new technique reaches 96%.
The object of analysis was the concentration of 10 chemicals directly related to this serious disease. The study, which lasted 5 years, involved 525 elderly people over 70 years old. All this time, they recorded in detail their state of health. 28 study participants developed Alzheimer's disease and other cognitive impairments usually preceding it. After carefully examining their blood tests, the researchers concluded that fats (lipids) are the best indicator of a dangerous illness.
Studies have shown that people who are prone to Alzheimer's have significantly lower blood lipids than those who are not. The fact is that a decrease in lipid concentration leads to disruptions in the interaction of neurons in the brain.
According to the project participants, the next step should be to bring the prognosis of the disease from 10 to 20 years, and in the future, the development of appropriate drugs, which are not yet available, as well as there is no method of treating Alzheimer's disease. In the meantime, a diagnosis made and announced in advance will allow a person to inform his family members about it, put financial and legal matters in order, and organize future care.
