EGb 761 is a particular extract of Ginkgo biloba used in Europe to alleviate symptoms associated with numerous cognitive disorders.Its use in dementias is based on positive results from only a few controlled clinical trials,most of which did not include standard assessments of cognition and behavior.EGb was safe and appears to be capable of stabilizing and,in a substantial number of cases,improving the cognitive performance and the social functioning of demented patients for 6 months to 1 year.Although modest,the changes induced by EGb were objectively measured by the ADAS- Cog and were of sufficient magnitude to be recognized by the caregivers in the GERRI. |
