Lisa Mosconi and her associates administered PET scans to research participants to measure activity in the hippocampus. They found that participants with low hippocampus activity were more likely to develop neurocognitive disorders later in life. How accurate were their predictions?

over 70 percent accurate for mild neurocognitive impairment, and over 80 percent accurate for major neurocognitive impairment

Explanation:

Lisa Mosconi and her associates in a research titled "Hippocampal hypometabolism predicts cognitive decline from normal aging" reported that over 70 percent of participants with low hippocampus activity developed mild neurocognitive impairment, and that their predictions was over 80 percent accurate for major neurocognitive impairment.
