taking high doses of vitamin B tablets a day can halve the rate at which shrinks the brain in older people with memory problems and slow the progress of the problem to dementia, data showed a British study.
Scientists at the Oxford University clinical trial indicated that their two-year project is the largest to date on the effect of B vitamins in the "mild cognitive impairment, an important factor risk of Alzheimer's disease and other forms of dementia.
Experts who commented on the results of the study described as important and urged that more frequently than large-scale trials to see if you can confirm the safety and effectiveness of B vitamins in the prevention of neurodegenerative conditions.
"This is a very dramatic result (...) It is much more than we could have predicted," said David Smith, the department of pharmacology at Oxford, who co-directed the study.
"We hope this simple and safe treatment delayed the development of Alzheimer's in many people suffering mild memory problems, "added Smith.
Mild cognitive impairment (MCI) affects about 16 percent of people older than 70 years and is characterized by mild problems with memory loss , language and other mental functions.
Although MCI does not usually interfere with daily life, about 50 percent of people diagnosed advancing Alzheimer's disease, more severe, in some five years.
Alzheimer's is a neurodegenerative condition that affects 26 million people around the world and for which there are few treatments and no cure option at the moment.
Smith and his colleagues studied 168 volunteers with MCI who received a pill with high doses of folic acid, vitamin B6 and B12 or a placebo pill.
These B vitamins are known to control blood levels of an amino acid called homocysteine. Huge amounts of homocysteine \u200b\u200bin the blood is linked with an increased risk of developing Alzheimer's disease.
Helga Refsum, who also worked on the study, said that were handled extremely high doses of vitamins. "This is a pharmacological intervention, no vitamins," he said.
pills called "TrioBe Plus", contained about 300 times the recommended daily intake of B12, four times the recommended levels of folic acid per day and 15 times the scheduled amount as the daily limit for Vitamin B6.
The results, published in the journal PLoS One, showed that on average, the brains of those who took vitamins shrank at a rate of 0.76 percent annually, while among those taking placebo had an average of brain shrinkage was 1.08 percent .
People with higher homocysteine \u200b\u200blevels at baseline benefited most from treatment because their brains were cut in half the rate than did those who took the fake pills.
