One glass of wine a day can damage the brain

One glass of wine a day can damage the brain

Through these, the researchers were able to analyze the volunteers' brain functions.

The new long-term study by researchers at the University of Oxford and University College London, supports the UK's new guidance on alcohol consumption introduced previous year.

As part of this study, researchers studied a sample's alcohol intake from the Whitehall II study, which has been tracking ailments and social behavior of a group of British civil servants for the past three decades.

It was also found that people who drink more than seven units of alcohol per week showed a faster decline in language fluency compared to the non-drinkers.

The researchers note this is an observational study, so they can not draw any conclusions relating to cause and effect. Topiwala stressed, "I wouldn't recommend light to moderate drinking as a strategy to avoid cognitive decline". Even though the reduction is not as significant as that among heavy drinkers, it can still signal dementia. Those consuming more than 30 units of alcohol saw an nearly sixfold rise in their risk.

The researchers defined a unit as 10 millilitres (ml) of pure alcohol. Obviously, plenty of people regularly have more than this at happy hour or on the weekend, which makes these new findings more than a little freaky. "There is growing evidence that moderate alcohol intake may be a risk factor for atrial fibrillation, the most common heart rhythm disturbance in the world, but the mechanism by which alcohol may lead to atrial fibrillation is unknown", Gregory Marcus, researcher at the University of California, San Francisco was quoted by IANS.

The study found that 13.6% of the women and 20% of the men were over the safe limits and that even moderate drinkers' brains suffered long term effects from alcohol.

Rimm was not involved in the study.

"But the study needs to be replicated and, importantly, with women".

If you are a moderate drinker, he said, you don't have to give up the booze based exclusively on this report. They point out that this research did not take into account various lifestyle factors, including nutrition. "Eating whole grains and fruits and vegetables have been linked to slower cognitive decline".

Still, other researchers tend to disagree with the study results. In many studies, it includes former drinkers who likely quit for health reasons - whereas people who continued to drink as they aged were probably healthier to begin with. The team reports being surprised by the lack of "protective effects" of this habit.

Those who had between 14 to 21 drinks per week were three times as susceptible to the condition, the study found.

"These type of studies also can not account for all the (factors), and therefore they can not, and should not, conclude causation", Heneghan said.

Furthermore, there seemed to be a direct correlation between how much the participants drank and the level of shrinkage.

Heavy drinking is known to be associated with poor brain health, but few studies have examined the effects of moderate drinking on the brain, and results so far were inconsistent.
