Blood tests offer clue to dementia risk
Blood tests using biomarkers could be used to predict dementia risk
Scientists have developed blood tests that can predict dementia risk. The importance of blood-based biomarkers is that they can improve the identification of people at greatest risk of dementia through low-cost and minimally invasive screening.
These people can then be included in future trials to find ways to prevent the development of dementia.
The aim of this study was to investigate the use of plasma total tau as a blood biomarker for dementia and related endophenotypes – cognitive or physiological characteristics that can be measured but are not visible and may be detectable even if the disease is not present.
