Alzheimer’s Disease and Non-Alzheimer’s Dementia The scientific record for ginkgo in these conditions is extensive and impressive. According to a 1992 article published in Lancet, over 40 double-blind controlled trials had been performed by that date, evaluating the benefits of ginkgo in treating severe age-related mental decline.2 Of these studies, which involved about 1,000 participants, eight were rated of good quality and all but one produced positive results. Most of these studies were performed prior to a full recognition of the identity of Alzheimer’s disease, but they are presumed to have involved both Alzheimer’s and non-Alzheimer’s cases. The authors of the Lancet article felt that the evidence was strong enough to conclude that ginkgo extract is an effective treatment for severe age-related mental decline.
