Participant gender:
All
Summary
The purpose of this study is to examine the effects of blood pressure medications on cognition and blood flow in hypertensive elderly patients with cognitive impairment. The hypothesis is that treatment with an angiotensin receptor blocker (ARB) or an angiotensin-converting enzyme inhibitor (ACEI) will be associated with a slower rate of further cognitive decline, improved cerebral blood flow and its regulation, and preserved physical function as compared to treatment with a diuretic (HCTZ), independent of blood pressure level.
