[Drug therapy of disorders of cerebral performance. Randomized comparative study of dihydroergotoxine and Ginkgo biloba extract].

In a randomized trial lasting six weeks and involving 80 elderly patients with cerebrovascular disorders, the effectiveness and tolerance of dihydroergotoxine was compared with an extract of Ginkgo biloba. On the basis of psychometric tests and assessment scales, it was shown that treatment with either substance improved the condition of the patients. While, for the most part, intergroup comparison revealed no major statistically significant differences, such changes, affecting various parameters, were found during follow-up--more frequently within the dihydroergotoxine group than within the group treated with Ginkgo biloba extract.
