B vitamins found to slow

Daily tablets of large doses of B vitamins can halve the rate of brain shrinkage in elderly people with memory problems and may slow their progression toward dementia, data from a British trial showed on Wednesday,
Scientists from Oxford University said their two-year clinical trial was the largest to date into the effect of B vitamins on so-called "mild cognitive impairment" -- a major risk factor for Alzheimer's disease and other forms of dementia. click here for cheap dvds
Experts commenting on the findings said they were important and called for larger, longer full-scale clinical trials to see if the safety and effectiveness of B vitamins in the prevention of neurodegenerative conditions could be confirmed.
"This is a very dramatic and striking result. It's much more than we could have predicted," said David Smith of Oxford's department of pharmacology, who co-led the trial.
It is our hope that this simple and safe treatment will delay development of Alzheimer's in many people who suffer from mild memory problems." click here for cheap dvds
Mild cognitive impairment (MCI) affects around 16 percent of people aged over 70 worldwide and is characterized by slight problems with memory loss, language or other mental functions.
People who had the highest levels of homocysteine at the start of the trial benefited the most from the treatment, with their brains shrinking at half the rate of those on the placebo.
Although the trial was not designed to measure cognitive ability, the researchers found those people who had lowest rates of shrinkage had the highest scores in mental tests.
