Cerebral and Peripheral Perfusion Pilot Study

Summary

The purpose of this study is to evaluate the hypothesis that in middle-aged, asymptomatic, adult children of persons with Alzheimer's disease (AD), atorvastatin therapy will beneficially affect mechanisms thought to contribute to AD risk by improving blood flow in the brain, improving cerebral perfusion, increasing brain activity patterns, and improving blood vessel function.
