HealthDay News — A blood test has been developed that can predict with 90% certainty whether a senior will suffer from dementia such as Alzheimer disease within the next few years, according to a study published online March 9 in Nature Medicine.
The test relies on levels of 10 lipids in the bloodstream to estimate the chances of either mild cognitive impairment or the beginnings of Alzheimer disease.
The study involved 525 healthy people aged 70 years or older who underwent a full blood exam and a battery of neurocognitive tests. The research team then followed the participants for 5 years. During the course of the study, 74 of the people developed dementia or mild Alzheimer disease.
