Crystal Ball on Frailty?
The frail elderly are easy to spot: they tend to be thin and weak, with little energy and a slow and unsteady gait. first recognized as a medical condition in 2001, frailty is too often the beginning of the end.
Now a Johns Hopkins team has found that the amount of mitochondrial DNA in peoples’ blood directly relates to how frail they are medically. this DNA may prove to be a useful predictor of overall risk of frailty and death from any cause some 10 to 15 years before symptoms appear— giving doctors the head start they need to improve fitness in at-risk individuals with drugs or lifestyle changes.
"We don’t know enough yet to say whether the relationship is one of correlation or causation, but either way, mitochondrial DNA could be a very useful biomarker in the field of aging," says Dan Arking, associate professor of genetic medicine. the scientists reported on their work in the online Journal of Molecular Medicine.
