Can an acute dosage of Bacopa Monniera (brahmi) improve cognition, cardiovascular function and stress in an elderly population

This research project is aiming to determine the effects of Bacopa on cognitive function, cardiovascular function and stress. Bacopa is a herb found in wetlands and muddy shore lines that has been used in traditional Indian medicine as a treatment for epilepsy and asthma. Russo & Borrelli (2005) claim that it has been used for over 3000 years as a memory and intellect enhancer. There is also evidence to suggest that Bacopa is an antioxidant, playing an important role in reducing the oxidation of fats in the bloodstream. This study will investigate the cognitive, cardiovascular and stress effects of two doses of bacopa compared to placebo. Participants will be required to attend three testing sessions (and one practice session). Each session will see participants taking one of three interventions (administered in capsules); (1) Bacopa Monniera – 300mg (2 x 150mg capsules, 2 x placebo capsules) (2) Bacopa Monneria – 600mg (4 x 150mg capsules) (3) Placebo (4 x capsules) On the testing days participants will complete baseline testing (consisting of the cognitive battery, cardiovascular measures and stress testing) after which they will be administered their randomly assigned treatment. Two hours post dose participant will complete the testing again (cognitive battery, cardiovascular measures and stress testing). There will be a seven day washout period and the process will be repeated again. Over the course of the investigation, participants will complete all three treatments with treatment order being randomised and counterbalanced across participants. Russo, A. and F. Borrelli (2005).
