“Administration of Ginkgo produced a number of significant changes on the performance measures. The most striking of these was a dose-dependent improvement of the 'speed of attention' factor following both 240 mg and 360 mg of the extract, which was evident at 2.5 [hours] and was still present at 6 [hours].” See full study.

“Overall, the results from both objective, standardized, neuropsychological tests and a subjective, follow-up self-report questionnaire provided complementary evidence of the potential efficacy of Ginkgo biloba...in enhancing certain neuropsychological/memory processes of cognitively intact older adults, 60 years of age and over.” See full study.

“[Gingko biloba] at 240 mg/day is able to stabilize or slow decline in cognition, function, behavior, and global change at 22-26 weeks in cognitive impairment and dementia, especially for patients with neuropsychiatric symptoms.” See full study.

Changes from baseline in Appointments Test scores were less than 0.5 in the placebo group and over 2 in the Ginkgo group. See full study.

“Statistical analysis indicated significant improvements in speed of information processing working memory and executive processing attributable to the EGb.” See full study.

“After 6 months of treatment, the scores of the logical memory test and nonsense picture recognition were increased significantly in the treatment group (P<0.01, P<0.05), while the scores of the two tests from the control group had no statistically significant difference (P>0.05).” See full study.

“This study suggests that GBE poses a protective role from the various pathologies associated with high-fat diets, unpredictable chronic mild stress, and depression, possibly via improving peripheral immunity and reducing cardiac and brain inflammation.” See full study.

“Therefore, it is suggested that Ginkgo biloba extract is an effective agent against trimethyltin-induced hippocampal neuronal loss owing to its antioxidative as well as anti-inflammatory properties.” See full study.

“The results suggest that G. biloba biflavones could inhibit the activity of leukocyte elastase. This in turn implicates G. biloba as a functional food for the treatment of airway inflammation.” See full study.
