In a comprehensive review of current scientific data, a clinical neuropsychologist has found that gingko biloba not only improves declining memory, but also offers considerable benefits for other cognitive functions.
Dr. Reiner Kaschel of the University of Osnabrueck, Germany, analyzed the findings of 29 published clinical trials and found that patients who took gingko extract showed significant positive effects compared to those who took a placebo.
The study concluded that the compound improved memory, concentration, attention and executive functions of respondents showing the first signs of cognitive decline.
Kaschel estimated that those who took gingko extract were between four and eight times more likely to experience improved brain function when compared to those in the control group.
He concluded that "there is consistent evidence that chronic administration [of ginkgo extract] improves selective attention, some executive processes and long-term memory for verbal and non-verbal material."
Gingko biloba has also been used to help patients recover from eye problems including glaucoma, diabetic eye disease and age-related macular degeneration.
Gingko extract has been linked to the improvement of blood circulation, which may help the brain, eyes, ears and legs function properly.
