A protein in the blood of older women is associated with an increased risk of cognitive decline and dementia
A new study conducted over 25 years with data from 2,766 older women, who were in good cognitive health at the start, shows that high blood levels of the p-tau217 protein were strongly associated with future mild cognitive impairment and dementia. In its press release, the University of California (United States), where the authors work, stated that ‘a new blood biomarker can predict a woman's risk of developing dementia up to 25 years before symptoms appear.’ The study is published in the journal JAMA Network Open.
