Alzheimer’s Information: Do Dietary Supplements Really Make a Difference in Alzheimer’s or Dementia? (Part 1)
Gingko Biloba – Gingko has been marketed extremely successfully as a memory aid and treatment for Alzheimer’s disease and is the most popular of the purported memory enhancing dietary supplements. The evidence of its effectiveness is conflicting, at best. Small-scale studies have shown minor memory improvement for patients taking the supplement, but other studies have shown that Gingko has no effect whatsoever on improving memory or slowing the progression of Alzheimer’s.
A recent study of 200 men and women with dementia and Alzheimer’s showed Gingko to be of no use to memory impaired patients. In the study, the participants were divided into two groups, testing for to determine their cognitive abilities, and then one group was given Gingko and the other group took a sugar pill. After 12 weeks, the testing was repeated, and then the Gingko group was divided in half again, with half of those patients now receiving a sugar pill as well. At the end of the study, it was determined that Gingko did not offer an improvement to memory, and that the amount of time a patient took the Gingko was irrelevant as well.
In addition to the lack of proof that it is effective at all, Gingko Biloba can be harmful to some patients, especially those taking blooding thinning medications, including aspirin, or antidepressants (which Alzheimer’s patients typically take). There is also no data on what is a safe dosage of Gingko.
