Patient blood samples reveal biomarkers for dementia risk

March 6 (UPI) — It may be possible to predict risk for dementia based on biomarkers in blood samples, according to a new study by researchers in Texas. Small molecules called metabolites in blood samples drawn from 22,623 individuals in eight cohort studies in five countries, including 995 people who went on to develop dementia, seem to show risk for developing dementia. High-density lipoprotein, known as HDL, and a VLDL lipoprotein subclass, on the other hand, were linked with increased dementia risk.The Glenn Biggs Institute hopes to develop a diagnostic exam, such as a blood test, to assess each patient’s molecular signature of dementia risk. “It is exciting to find new biomarkers that can help us identify persons who are at the highest risk of dementia.”
