Dementia

Many of us are likely to suffer from dementia as we drink, breathe and wallow in an ever more poisonous environment (SAsians more than most). It is imperative to be able to predict this condition in advance. Once the tell-tale signs are confirmed, we can go out and have a gala party, sign off on the will (please do that anyway), take a boat out to the sea and...jump in with the fishes.

Only one small question: 90% accuracy sounds very impressive (also likely to improve over time), but is it??

...
A study, published in the journal Nature Medicine, identified 10 molecules in blood could be used to predict with at least 90% accuracy whether people will go on to develop mild cognitive impairment or Alzheimer's.

"The lipid panel was able to distinguish with 90% accuracy these two distinct groups: cognitively normal participants who would progress to MCI or AD within two to three years, and those who would remain normal in the near future," said one of the study's authors, Professor Howard Federoff.

Dr Doug Brown, director of research and development at the Alzheimer's Society, added: "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.
