Notes
grade-b Minor Very High See all 9 studies
Appears to preserve working memory during acute stressors. Acute stressors include temperature changes, psychological, and sleep deprivation. It's not clear if it has inherent memory-improving effects, as most research doesn't examine this, and what research we do have is mixed.
grade-b Minor Very High See all 5 studies
An improvement in working memory is noted in most persons tested, even otherwise healthy and nonfatigued controls.
grade-b - Very High See all 3 studies
Despite the improvement in short term memory and recall, there does not appear to be a significant improvement in working memory.
