Abstract: Effectiveness of a Ginkgo Special Extract an Psychometric Parameters in Patients with Vascular Dementia: The efficacy of Ginkgo biloba extract an cerebral functional capacity and well-being was studied in a placebo-controlled double-blind trial including 52 ambulant patients with vascular dementia. Over a period of 3 months 3 x 20 ml of a drinking solution were prescribed, which was equivalent to a daily dosage of 150 mg of Ginkgo biloba special extract. Concerning improvement of the symptoms as well as psychometric tests an unexpected strong placebo effect was observed; the verum treatment was only tendentially superior, but not signifi-cantly. At a total study duration of 2 years stability of the drinking solution was possibly not sufficient, so that reserve concerning a longer application of such preparations is recommended.
