Blood test that can show if someone gets Alzheimer’s is within reach | Right away
American scientists announced Tuesday that a new blood test that will almost certainly determine whether a person will develop Alzheimer’s disease in the future will be available in a few years. This is particularly important for the development of a drug for the most common form of dementia, Deputy Director Marco Blom of Alzheimer’s Netherlands said on Wednesday NU.nl.
The test can distinguish whether people with dementia get Alzheimer’s or another memory disease. According to the researchers, this can be seen in the blood for 10 to 15 years before a person develops symptoms.
“The new blood test is an important step because it can lead to a new drug. Therefore, early detection of the disease can also lead to early treatment of the disease in the future,” says Blom.
Within science, there is an enthusiastic reaction and the blood test is considered a step forward. Current Alzheimer’s patients, however, have not been helped, he agrees.
Amsterdam misses Congress over Corona crisis
- The Alzheimer’s test is the biggest news at the Alzheimer’s Association’s International Conference, which is taking place this week. The largest conference for dementia researchers from all over the world was to take place at the RAI in Amsterdam, but because of the coronavirus, which “neurological party” did not advance. Instead, dementia scientists now participate virtually in lectures and presentations.
96 percent chance of correct test results
The probability that the blood test will produce the correct result is Researchers Nine-six percent. That sounds fantastic, “but if you treat 100 people with medication, four people won’t be able to do that in this case,” Blom says.
He believes more research is needed to get this 100% certainty.
Nor is it a question of benefiting him, it does not harm. The treatment is too expensive and too stressful because of the risk of side effects, Blom explains.
Do you even want to know if you get Alzheimer’s?
As with other dementias, there is no cure for Alzheimer’s disease. Still, scientists in the United States are already far from developing a possible cure for Alzheimer’s disease. They hope to get this drug on the U.S. market within a year.
The chances of such a drug being caught in someone with an advanced stage of dementia are slim, blom says. “Simply put, there are already too many holes in the head. That’s why it’s important to recognize the disease as early as possible,” he says. The new Alzheimer’s test could play an important role in this.
Finally, the test also raises an ethical question. “Because she and your family want to know if you get Alzheimer’s? If so, you can adjust your life to it. At the same time, you are just as entitled not to know. These are complex compromises that need to be carefully considered,” says Blom.
Correction: NU.nl first erroneously created the image that the blood test predicts whether someone will develop analzheimerism within 15 years or not. It’s a little more nuanced. With the test, the researchers can only distinguish Alzheimer’s disease in people with dementia.
