Do we know years in advance if dementia will develop later? British and Chinese researchers have identified at least eleven proteins in our blood that can predict dementia very accurately.

A breakthrough, that’s what researchers from the University of Warwick and Shanghai Fudan University call their discovery. The eleven proteins they identified were found in blood plasma, the liquid component of blood without blood cells or platelets. Proteins are so-called biomarkers or indicators of biological changes that occur in dementia or Alzheimer patients. According to a study that appeared in a scientific journal Naturethe presence of proteins indicates dementia in nine out of ten cases.

Researchers analyzed blood samples from more than 50,000 healthy Britons between 2006 and 2010. More than 1,400 of them developed dementia in the next 10 to 15 years. By analyzing the proteins in their blood and using artificial intelligence, the researchers found that these eleven proteins can predict dementia up to fifteen years before diagnosis.

And having this information so early is very helpful because it allows patients to start medications at a very early stage that slow the progression of the disease, which also improves the effectiveness of these medications.

“It’s still very early days and we still have a lot to do, but this could lay the groundwork for early prediction of dementia and teach us more about its early and accurate diagnosis,” said Richard Oakley of Alzheimer’s UK. society Independent.

More than 55 million people worldwide suffer from dementia. The number is expected to rise to 78 million by 2030. About 70 percent of all dementias are caused by Alzheimer’s disease.
