Caffeine and Cerebrovascular Reactivity
NCT04730193 · Status: COMPLETED · Phase: EARLY_PHASE1 · Type: INTERVENTIONAL · Enrollment: 10
Last updated 2022-08-09
Summary
Caffeine is the most commonly used stimulant drug with well documented effects on cerebral vascula-ture. Caffeine is known to non-specifically bind to adenosine receptors in the brain and to reduce resting blood flow while improving attention and cognitive function, which suggests that it may allow a more efficient dynamic blood flow regulation through neurovascular coupling. This study will use standardized dose of caffeine to test its effect on NVC responses in cerebral and retinal arterioles.
