Scientists may have found a way to detect Alzheimer's disease earlier: a simple, midlife blood test.

Researchers at the University of Michigan have made a connection between two blood biomarkers and cognitive function in middle-aged women. To reach these findings, published in the Journal of the Alzheimer's Association, the scientists analyzed these two biomarkers in 192 middle-aged women. They also tested their neurological function.
