Scientists have discovered four proteins that can predict the development of dementia almost 15 years before diagnosis.


This is reported by The Guardian with reference to a study published in the scientific journal Nature Aging.


Combined with traditional risk factors (age, sex, education, and genetic predisposition), protein profiles made it possible to predict dementia with an accuracy of 90% almost 15 years before people were officially diagnosed.


For the study, Chinese scientists used blood samples from more than 52 thousand healthy British adults from the UK Biobank database. They were collected and frozen between 2006 and 2010. More than 1.4 thousand of all participants developed dementia.
