  Purpose

The purpose of this study is to determine if a reduction in systolic blood pressure induced by anti-hypertensive medication results in changes in cerebral perfusion and cognition in hypertensive elderly. Hypertensive elderly will be treated using open-label anti-hypertensive medication for 8-12 weeks. Changes in cerebral perfusion and cognition will be assessed before and after treatment.
