Researchers at the UCLA Neuropsychiatric Institute found Gingko Biloba triggers significant improvement in verbal memory in subjects with age-associated memory impairment compared to placebo.

Many earlier studies with Ginkgo Biloba have produced conflicting results. According to this article, however, most previous studies involving Gingko lasted less than 3 months. The current study is felt to be rather unique because of its longer duration (6 months). The UCLA is also notable in that it tracked brain changes via PET scans.

Unfortunately, however, the study size was quite small (10 patients).
The dose utilized was 120mg of Ginkgo twice a day.
