Does Ginkgo "from the head" not help?

The extract of two-lobed gingko (ginkgo biloba, Ginkgo biloba), advertised almost as the most effective remedy for dementia associated with circulatory disorders and Alzheimer's disease, is not. A study conducted by scientists from the University of Pittsburgh showed that this drug does not help either "healthy" old people in prevention or "moderately ill" in the treatment of dementia.

Published in the influential Journal of the American Medical Association, the work was carried out on the basis of several clinics at once, so there is no doubt about the reliability of the data. In total, scientists observed 3,069 volunteers aged 75 years and older from 2000 to 2008, who were divided equally – half received an extract, half received a harmless drug. The experiment was conducted in accordance with the norms of a double-blind study, when neither those who take the drug, nor those who evaluate its effect, do not know whether they are dealing with a test substance or a placebo.

Taking 120 mg of the extract per day had no effect on the normal processes of aging and age–related degeneration of nervous tissue - at least according to magnetic resonance imaging and angiography (vascular mapping). The difference in the final result could not be demonstrated either – dementia developed in 277 patients in the ginkgo group, and in 246 in the placebo group; mortality also did not differ statistically significantly.

The authors of the article, who did not dare to enter into a dispute with pharmaceutical giants, cautiously noted that the effect may not have been noticed due to the relatively short follow-up period for studying such diseases.
