...second brain-function study, published in the same journal, scientists in Germany found that increased physical activity was associated with a lower incidence of dementia. In this study, researchers recruited 3,485 elderly residents in Bavaria and asked them about their physical activity.

Taken together, the two evaluations strongly suggest that ginkgo does little, if anything, to improve acuity in cognitive functions such as memory, language, and visual and spatial orientation...
