NCT ID NCT04601038

First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time

Summary

This study tests whether a drug called CORT108297, which blocks a stress hormone, can improve memory and thinking in people with mild cognitive impairment or those at risk for Alzheimer's disease. Participants take the drug or a placebo for two weeks, then complete memory and attention tests after a stressful task. The goal is to see if reducing stress-related brain changes can help protect cognitive function.
