Brain shrinkage, declining function and memory loss had been thought to be irreversible. They used a technique known as deep brain stimulation - applying electricity directly to regions of the brain.
Overview: Ginkgo (Ginkgo biloba) is one of the oldest living tree species and its leaves are among the most extensively studied herbs in use today. In Europe and the United States, ginkgo supplements are among the best-selling herbal medications. It consistently ranks as a top medicine prescribed in France and Germany. Ginkgo has been used in traditional medicine to treat blood disorders and enhance memory. Scientific studies throughout the years have found evidence that supports these claims.
no ta, i have that one already, its why exams and the like have never posed a problem to me, i remember in video (or thats the best way i can describe it) if i want to remember where i put something for example i just run the bit where i had it last and i know where it is if that makes sense at all, until i was about 12 i imagined it was how everyone remembered, it amazed me when people told me that it wasnt and i still dont quite know how other people get by in life without it strangely sound is not so clear, i can remember seeing someone say something to me but not often all the words, and some parts of my earlier memories have no colour, i can still see the "video" but its all in a kind of greenish tinted greyscale, a strange old thing that grey matter 3/05/11 1:05am <p style="text-align:right;color:#A8A8A8"></p>
An Alberta Heritage Foundation for Medical Research Senior Scholar, Poulin finds that physical activity benefits blood flow in the brain , and, as a result, cognitive abilities. "Being sedentary is now considered a risk factor for stroke and dementia ," says Poulin, a scientist in the Faculties of Medicine and Kinesiology at the University of Calgary. "This study proves for the first time that people who are fit have better blood flow to their brain.
A French study estimates the percentage reduction in incidence of dementia that would be obtained if specific risk factors were eliminated. Karen Ritchie, from the French National Institute of Health and Medical Research (INSERM), and colleagues assessed lifestyle data collected from 1,433 men and women, average age 72.5 years, who were followed for 7 years to track the onset of dementia. The researchers found that reducing the rate of depression would slash dementia by 10.3%, and eliminating diabetes would result in a 5% reduced dementia rate. As well, completing more education was associated with an 18.1% reduced rate, while increasing fruits and vegetable consumption cut dementia by 6.5%.

Dec. 24, 2008 — All that chocolate might actually help finish the bumper Christmas crossword over the seasonal period. According to Oxford researchers working with colleagues in Norway, chocolate, wine and tea enhance cognitive performance. The team from Oxford’s Department of Physiology, Anatomy and Genetics and Norway examined the relation between cognitive performance and the intake of three common foodstuffs that contain flavonoids (chocolate, wine, and tea) in 2,031 older people (aged between 70 and 74).
Feb. 9, 2009 — Researchers at the Swedish medical university Karolinska Institutet have shown for the first time that the active training of the working memory brings about visible changes in the number of dopamine receptors in the human brain. The study, which is published in the journal Science , was conducted with the help of PET scanning and provides deeper insight into the complex interplay between cognition and the brain's biological structure. "Brain biochemistry doesn't just underpin our mental activity; our mental activity and thinking process can also affect the biochemistry," says Professor Torkel Klingberg, who led the study.
"The benefit is roughly equivalent to having the learning and memory skills of someone three years younger," he said. The study was one of two into the affect of DHA presented at the international Alzheimer's Association meeting in Vienna, Austria. The first found that it did nothing to slow memory declines in people with mild to moderate Alzheimer's disease, but the second in healthy people with slight memory complaints did show promise. The second group also showed a "significant decrease" in heart rate.
