Evaluate the Effect of Atorvastatin on Cerebrovascular Reactivity in Mild Cognitive Impairment (MCI)

This Phase 2 trial is testing whether atorvastatin, a common cholesterol-lowering drug, can improve how well blood vessels in the brain respond and regulate blood flow in people with mild cognitive impairment. Phase 2 means researchers are exploring whether it works and that it is safe in this group — it is not proven or approved for this purpose yet.
