New blood test 'could detect dementia early'


SCIENTISTS have developed a blood test that could detect whether or not a person will develop dementia within three years.

Blood changes may signify Alzheimer's disease in its earliest stages, researchers found.

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

It is the first research which has been able to show differences in biomarkers in the blood between people with Alzheimer's disease before the symptoms occur and people who will not go on to develop the condition.

The finding has potential for developing treatment strategies for Alzheimer's earlier.

Georgetown University Medical Centre researchers found 10 molecules which appeared to "reveal the breakdown of neural cell membranes in participants who develop symptoms of cognitive impairment or Alzheimer's disease".
