Large doses of B-complex vitamins could reduce the rate of brain shrinkage by half in elderly people with memory problems and slow the progression of dementia.
A two-year clinical trial in England has shown that B vitamins, including B-6, B-12 and folic acid, slow down mild cognitive impairment (MCI), a condition which is a major risk factor for Alzheimer disease and other forms of dementia. [continue reading…]

A new study shows that vitamin B12 may protect against Alzheimer’s disease, adding more evidence to the scientific debate about whether the vitamin is effective in reducing the risk of memory loss. The research will be published in the October 19, 2010, issue of Neurology®, the medical journal of the American Academy of Neurology. [continue reading…]
Although most people assume that tests are a way to evaluate learning, a wealth of research has shown that testing can actually improve learning, according to two researchers from Kent State University. Dr. Katherine Rawson, associate professor in Kent State’s Department of Psychology, and former Kent State graduate student Mary Pyc publish their research findings in the Oct. 15, 2010, issue of the journal Science.
“Taking practice tests – particularly ones that involve attempting to recall something from memory – can drastically increase the likelihood that you’ll be able to remember that information again later,” Rawson said. “Given that hundreds of experiments have been conducted to establish the effects of testing on learning, it’s surprising that we know very little about why testing improves memory.” [continue reading…]
