Ginkgo biloba

I have in the past written about the potential of Ginkgo Biloba in the prevention of memory loss.  In the interest of fairness, I need to tell you about the latest research findings in this regard.  In a study recently published in the Journal of the American Medical Association, 240 milligrams per day of the dietary supplement Ginkgo Biloba was found to be statistically ineffective in reducing the development of dementia and Alzheimer’s disease in older people.

3,069 people age 75 or older were followed by the study for an average of 6 years each.  They started out with normal cognition or mild cognitive impairment.  People who already had dementia were excluded from the study. Study participants were given twice-daily doses of either 120 milligrams of ginkgo extract or a placebo. The study was primarily designed to find out whether ginkgo would decrease dementia, especially Alzheimer’s disease.  A second purpose was to evaluate ginkgo for its effects on generally cognitive decline, such as memory loss, disability, cardiovascular disease, stroke, and total mortality.

Dr. Steven T. DeKosky was the lead researcher on the project.  At the conclusion of the study, he said, “The results of this study confirm the importance of randomized trials in the development of new therapies for dementia and Alzheimer’s disease and in determining therapeutic benefit not only for conventional therapies but also complementary therapies like ginkgo… If older patients are considering using ginkgo for preventing dementia, I urge them to speak with their health care providers about the results of this study and work together to create the best treatment plan.”

523 of the participants were diagnosed with dementia during the study.  246 of them were in the placebo group and 277 were in the ginkgo group.  Therefore, the conclusion was that ginkgo showed no ability to reduce dementia or Alzheimer’s disease. However, the study did not find significant adverse effects from ginkgo either.  The next step is to analyze the data for conclusions about the other factors studied.  According to Kr. DeKosky, “Future analyses will provide us with additional information on ginkgo’s possible effects on cardiovascular disease, cancer, depression and other age-related conditions.”

It is important to emphasize that the only conclusions of the study thus far are related to dementia and Alzheimer’s disease.  People have been taking Ginkgo for many years, and it has been reported effective for the treatment of many conditions.  You shouldn’t go beyond the conclusions of the study to decide whether Ginkgo is effective in other ways.  I don’t take it but I know that many respected people do.  The use of any dietary supplement should be based on discussion with medical professionals.

Book Review: Welcome to Your Brain

by Bob McCluskey on January 25, 2010

Subtitle: Why You Lose Your Car Keys But Never Forget How to Drive And Other Puzzles of Everyday Life

by  Sandra Aamodt, Ph.D and Sam Wang, Ph.D
Paperback edition, 2009, 256 pages

I  have mentioned this book on several occasions. I have enjoyed it so much over the past few months that I decided to do a review of it. If you have any interest in the study of human psychology, human nature or how things work in general, you may want to read this book. Or, you may want to recommend it to someone.

The authors of the book are neuroscientists. In this book they attempt to explain some things about the human brain, with its 10 billion neurons. They are dealing with the very complex processes by which the brain coordinates sensory information and thoughts, regulates our emotions and forms memories.  They manage to pull it off with humor and clarity.

Aamodt and Wang take on some of the controversial issues related to human psychology. They discuss whether men and women have different brains. Their answer is “Yes,” but they are not sure how much difference it makes in terms of behaviors and capabilities. They also tackle the never ending debate about whether intelligence stems mainly from nature or nurture, heredity or environment. They conclude that heredity establishes some limitations around intelligence, but that environment, such as child rearing, significantly affects the degree to which individuals reach their genetic potential. The authors discuss the differences between humans and other mammals.  They reveal what is happening in the brain when we dream. Other topics include jet lag, and the effect of your brain on your religion.

I really enjoyed the numerous sidebars devoted to exploding brain myths. For example, it is not true that we only use 10% of our brain’s capacity. In fact, we use almost all of its capacity. The book was especially appealing to me because of its emphasis on how to protect the brain as we age. It is a lively and humorous work, with lots of illustrations, quizzes, trivia and charts. All in all, this is a book that is fun and practical at the same time. I know I will return to it time after time as a reference source and as a source of entertaining reading. The book is available at a discount from Amazon.com by clicking the image on this page. Let me know what you think of it!
