Researchers from the University of California San Diego have found a blood-based biomarker that can predict a woman's risk of developing dementia up to 25 years before symptoms appear. The study, published in JAMA Network Open, analyzed data from 2,766 participants in the Women's Health Initiative Memory Study and found that higher levels of phosphorylated tau 217 were strongly associated with future mild cognitive impairment and dementia.
A novel blood test can predict dementia in women up to 25 years before symptoms begin. The test measures levels of phosphorylated tau 217, a protein linked to brain changes seen in Alzheimer's disease. Researchers analyzed data from 2,766 participants in the Women's Health Initiative Memory Study. They found that higher levels of the protein were associated with future mild cognitive impairment and dementia. The study's findings suggest that earlier prevention strategies and targeted monitoring may be possible. The research was conducted by the University of California San Diego and published in JAMA Network Open.
