Who can join

Age: 55 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• age: 55 years or older;
• Hypertension: SBP≥140 mm Hg or DBP≥ 90 mm or receiving antihypertensive medications.
• Executive MCI will be defined using these criteria:
• The Montreal Cognitive Assessment (MoCA) score less than or equal to 26
• Executive dysfunction: A performance at the 10th percentile or below on at least one of four screening tests for executive function: Trail Making Test, Part B (TMT-B), modified Stroop interference, Digit Span and Digit Sequencing, and Letter fluency.
• Minimal Functional limitation as reflected by the Functional Assessment Questionnaire (FAQ)≤7

You may not qualify if…

• Intolerance to study drugs;
• SBP >200 or DBP >110 mm Hg;
• Renal disease or hyperkalemia
• Active medical or psychiatric problems
• Uncontrolled congestive heart failure;
• History of stroke in the past 3 years;
• Inability to perform the study procedures
• Women of childbearing potential
• diagnosis of dementia
• In those who lack decision capacity, a study surrogate who can sign on their behalf will be required. Since we are enrolling only those with MCI, we anticipate that most participants will have decision capacity
• Current use of Lithium, as most antihypertensive classes may lead to increased lithium toxic levels.
