Test to detect dementia tendency

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

Changes in the blood may signify Alzheimer’s disease in its earliest stages, researchers found.

A new 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 disease.
