Ginkgo shows cognitive benefits after a stroke

In this study, 333 men and women who had had a stroke due to a blockage of blood flow to the brain within the past seven days took 100 mg of aspirin per day, with or without 450 mg of ginkgo biloba extract in three divided doses per day, for six months.

Doctors measured cognition at 12, 30, 90 and 180 days and found those taking aspirin plus ginkgo biloba had higher scores at all four points compared to aspirin alone. The ginkgo group showed a significant slowdown in cognitive decline, and showed better attention, working memory, and cognitive flexibility—the ability to switch between two concepts.
