Forget using Ginkgo biloba for dementia.

A recent study found that ginkgo biloba did not improve cognitive function compared to placebo. This was a well-designed, 6 year randomized controlled trial. This proves my usual skepticism for dietary supplements. An interesting study to do would be to compare ginkgo biloba and Forrest's Namenda (memantine), and see how both do against placebo. In the meantime, better going back to using post-its and refrigerator notes.
