Drink any quantity of Liquor Be able to Increase the risk of development of dementiaNew research has shown.
Studies, led by researchers at Oxford University, Yale University and The University University of cambridgeData analyzed From more than 559,000 people In the UK Biobank and US Million Veteran Program. In the follow -up period, 14,540 participants developed dementia.
Result of Data on observation Were striking. Those who drink heavy alcohol are defined as 40 or more drinks a week, as well as 41 percent higher risk of developing dementia than those who had less than seven drinks a week. The risk for those who depended on alcohol increased to 51 percent.
But researchers also made genetic analysis using Genome-Wide Association Studies (GWAS) of 2.4 million people, causing the correlation to reject the correlation. He assessed three measures: self-reported weekly drinks, risky drinking and alcohol dependence.
In each case, a high genetic risk for alcohol consumption was associated with high risk of dementia. The authors said that this evidence reduced the idea that low levels of alcohol could protect the brain.
Researchers have previously suspected conclusions that groups that do not drink alcohol show worse health results in observation studies. This is due to the so-called “sick quality” effects, where people stop drinking alcohol due to illness, they are grouped with lifelong non-drinking.
A 2016 Analysis It was also found that once the former drinkers were excluded, the clear protective effect of lighting disappeared to a great extent.
The Oxford Population Health and Advisory Psychiatrist Senior Clinical Researcher Dr. Anya Topiwala said that these latest conclusions “challenge the common belief that low levels of alcohol are beneficial for brain health”.
He said: “Genetic evidence does not support for a protective effect, in fact, it suggests the opposite.
“Even drinking mild or medium may increase the risk of dementia, indicating that reducing alcohol consumption in the population can lead to an important role in the prevention of dementia.”
Professor of Yale University and senior writer of the study, Dr. Joelle Galenter said: “There was a time when it seemed to support medical knowledge that drinking light would be beneficial for brain health, and this task adds to the evidence that it is not correct.”
Cambridge Statistics Dr. Stephen Burges said: “Our findings not only hold for those who have a special genetic tendency, but whoever chooses to drink, our study shows that more alcohol consumption leads to a high risk of dementia.”
Alzheimer’s Research UK stated that the work was added to the evidence connecting alcohol to dementia, although it was insisted that more research was required.
According to the Alzheimer’s Society, around 982,000 people are currently living with dementia in the UK, a figure estimated to increase by about 1.4 million by 2040.
