Scientists are celebrating a revolution in blood testing for Alzheimer’s disease



Researchers on Tuesday said the blood test performed during the experiment was very accurate in detecting Alzheimer’s disease – a promising breakthrough that could make the diagnosis simple, accessible and widely available.

The test found out whether people with dementia had Alzheimer’s disease instead of another disease, the New York Times reported. It also found signs of Alzheimer’s disease for 20 years, while memory and thinking problems were expected in people with a genetic mutation that causes a degenerative, deadly disease, the conclusion said.

“This blood test is a very accurate predictor of who has been diagnosed with Alzheimer’s disease in their brains, including people who look normal,”

; Dr. Michael Weiner, an Alzheimer’s researcher at the University of California, San Francisco, told The Times.

The study was announced at the JAMA Network Open and presented at an international conference of the Alzheimer’s Association.

A blood test that has been performed as accurately as invasive methods such as MRI brain scans, PET scans, and spinal nipples is a much simpler and more accessible way to diagnose whether people with cognitive problems had Alzheimer’s rather than other types of dementia. .

Such a blood test can be used in the long run to predict whether someone is suffering from the disease, writes The Times.

“It’s not a cure, it’s not a cure, but you can’t cure a disease without being able to diagnose it. And an accurate and inexpensive diagnosis is really interesting, so it’s a turning point, “said Weiner, who did not participate in the study.

Experts said the test could be used clinically in two or three years.

Nearly six million people in the United States and about 30 million people worldwide suffer from Alzheimer’s disease. According to the report, by 2050 That number will more than double.
