Effect of Brain Pill on working memory capacity will be accessed by improvement in mean response time and accuracy measured by working memory battery from baseline to end of the study. Effect of Brain Pill is also accessed on Neurophysiological improvement in working memory as measured by electroencephelogram (EEG) from baseline to end of the study. Also improvement in attention and concentration will be accessed from baseline to end of the study by Picture recognition test.
Systematic reviews and meta-analyses of clinical human research using low doses of certain central nervous system stimulants found enhanced cognition in healthy people. In particular, the classes of stimulants that demonstrate cognition-enhancing effects in humans act as direct agonists or indirect agonists of dopamine receptor D1, adrenoceptor A2, or both types of receptor in the prefrontal cortex. Relatively high doses of stimulants cause cognitive deficits.
