Fluoride damages memory, but selenium may help reduce the damage
Editor's Note: Eat 2-3 Selenium Rich Brazil Nuts a Day.
'A new study in Wei Shen Yan Jiu (Journal of Hygiene Research) suggests that taking selenium supplements or eating selenium rich foods may help reduce the damage to neurons and minimize memory loss induced by fluoride, which is added in drinking water in the U.S.
Z. Zhang of Zhejiang Normal University in Jinhua, China and colleagues conducted the study and found supplementation of selenium in a moderate dose can decrease the toxic effect of fluoride. High doses of selenium can also cause side effects, the researchers found.'

What Power Naps Do To Your Memory
'For decades researchers have studied the science of sleep. Sleep problems are common in North America so the need to understand the suspension of consciousness is huge. Today scientists say with confidence that sleep not only provides our bodies with the restorative rest it needs, it can help our memory.
Short Naps and Sleep Problems
Evidence continues to indicate that power naps can boost our memory. U.S scientists say that a short nap allows the brain to absorb new information.'

Are You Absent-Minded or Easily Distracted? You May Have A Better Working Memory
'Do you zone out a lot at work, school or anytime for that matter? We all do it. We've all been disciplined for not paying attention at one time or another. Although some of us more than others, and I'll admit I fall into this category. A new study investigating the mental processes underlying a wandering mind reports a role for working memory, a sort of a mental workspace that allows you to juggle multiple thoughts simultaneously.
In recent years a number of academicians have ventured into this previously unexplored territory, trying to figure out why our minds wander while we're supposed to be paying attention. They were probably spurred on by the blank faces of their students during their stimulating lectures. But despite considerable interest in determining precisely why we zone out so often, scientists have been a bit unclear why we do it.'

How sniffing rosemary could boost your brain power

'Dr Mark Moss said: ‘We were not surprised by the improvement in cognitive performance following exposure to rosemary aroma as this has been demonstrated previously. ‘What excited us was the demonstration that performance was linked to plasma levels of 1,8-cineole following exposure.’
Tests on 20 people showed the natural compound was absorbed through the nose and into the blood plasma. For Dr Moss, this means there is a more traditional biochemical explanation for the increased cognitive performances previously demonstrated.
‘This compound is present in rosemary but has not previously been demonstrated to be absorbed into blood plasma in humans,’ he added. ‘It is our view that the aroma therefore acts like a therapeutic drug, rather than any effects being a result of the more sensory properties of the aroma.’ '

Three Herbs That Help Fight Alzheimer's.
'Alzheimer's disease, the most prominent form of dementia, is a progressive illness for which there is no cure; but there are plenty of options for preventing it and for reducing symptoms. This story is about three herbal cures in particular that lead the pack in alternative medicine: ginkgo; huperzine A; and turmeric.'

Walking Just 1 Mile a Day Helps Save Your Memory
'Walking an average of just one mile a day appears to protect against brain shrinkage in old age, which in turn helps stem the onset of memory problems and cognitive decline, new research reveals.
"We have always been in search of the drug or the magic pill to help treat brain disorders," noted Kirk I. Erickson, an assistant professor of psychology at the University of Pittsburgh and the study's lead author.
"But really what we are after may be, at least partially, even simpler than that. Just by walking regularly, and so maintaining a little bit of moderate physical activity, you can reduce your likelihood of developing Alzheimer's disease and [can] spare brain tissue."
A report on the research, which was supported by the U.S. National Institute on Aging, is published online Oct. 13 in Neurology.'
