New blood markers could predict dementia risk
Published 7 March 2014
A set of 10 molecules in blood could be used to predict with 90 per cent accuracy whether people are at greater risk of developing dementia within the next few years, according to researchers at Georgetown University Medical Center, USA.
'Right now we do not have a blood test that is currently available to predict the risk of someone getting dementia. Having such a test would be an interesting development, but it also throws up ethical considerations. If this does develop in the future people must be given a choice about whether they would want to know, and fully understand the implications.
'This research could also give clues on how Alzheimer's Disease occurs and warrants further study, but as such a small number of people showed dementia symptoms there need to be larger studies with different populations before it could be turned into a blood test for Alzheimer's Disease.'
