Abstract: Problem: The effect of ginkgo biloba extract EGb 761 on basic parameters of mental performance. Patients: Seventy-two outpatients with cerebral insufficiency at three test centers. Study design: Double-blind, randomized placebo-controlled study of 24 weeks duration. Test parameters: Psychometric computer-aided examination of the short-term memory and basic learning rate. Results: Statistically significant improvement in the shortterm memory after 6 weeks and of the learning rate after 24 weeks in the test substance group, but not in the placebo group (longitudinal analysis). The difference between the test substance and placebo groups (horizontal analysis) reached statistical significance in the 24th week. Conclusions: Treatment with ginkgo biloba extract EGb 761 improves mental/mnestic performance.
