A common blood test can flag early Alzheimer's disease patients who are four times more likely to experience rapid brain decline, a new study says.
The test -- the triglyceride-glucose (TyG) index -- assesses a person's level of insulin resistance and can estimate their risk of developing Type 2 diabetes.
But the test also can help determine which people newly diagnosed with Alzheimer's might experience a faster decline in brain function, researchers reported at the European Academy of Neurology's annual meeting.
"Once mild cognitive impairment is diagnosed, families always ask how fast it will progress," lead investigator Dr. Bianca Gumina, a neurology resident at the University of Brescia's Brain Health Center in Italy, said in a news release.
