Evidence Map

What The Sources Report

• As such, caffeine can enhance concentrations of important neurotransmitters such as dopamine, the result of which prevents alertness and attention decrements associated with low arousal. [Hearris Mark A. (2026); evidence level 4]
• The effects of caffeine on cognitive performance are, however, largely restricted to improved alertness and enhanced concentration or attention and do not typically extend to other cognitive domains such as working memory and executive function. [Hearris Mark A. (2026); evidence level 4]

How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

Practical Interpretation

For cacao flavanols cognitive performance randomized trial, the current source set is useful for orientation, but it is not yet broad enough for strong claims. Use cautious language and keep conclusions close to the cited sources.

Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
