Many researchers have studied Ginkgo biloba effects in supporting cognitive capacity in patients with dementia. A a small six-month controlled, double-blind trial found marked improvement in verbal recall in patients with memory impairment associated with aging. The researchers used a 3D imaging technique called positron-emission tomography to look at brain wave activity and found improvements in activity in portions of the brain associated with memory in patients taking ginkgo supplements.

The researchers concluded that ginkgo's effects may be due to improved blood flow to the brain and antioxidant activity of the herb.
