When done to excess , alcohol can be a risk factor for many diseases of the body . More recently , a new study found that middle-aged men who are heavy drinkers for years at risk of more rapid cognitive decline in old age .
The British study analyzed data on about 5,000 employees over a decade . The researchers found that male heavy drinkers two years earlier to experience a decreased ability to count and six years for the ability to remember faster than light or moderate drinkers .
The researchers admitted , this study is not the first study linking alcohol consumption with brain abilities . However , this study provides the age range the decline began to occur in heavy drinkers .
The study, published in the journal Neurology, also reveal the effects of cognitive decline occurs only in men . " However , the study participants consisted mostly of men . Thus , the number of women in the study may not be enough to make this conclusion is valid , " said Severine Sabia , the study researchers from University College London .
According to Sabia , there is no way to identify the specific minimum levels of alcohol consumption that can be risky for men . However , given the high risk , should limit everyone starts drinking alcohol since he was young .
The study uses data over 20 years . By using questionnaires , the researchers calculated the average consumption of alcohol daily for a decade until the man they hit the age of 56 years . Then, the researchers calculated a decrease in the ability of the brain every five years .
Acceleration of cognitive decline occurred in the group of heavy drinkers in the study amounted to 469 people . For information , the minimum amount that they drink is 385 milliliters 887 milliliters of wine or beer . Three times the maximum amount of it .
Meanwhile , Sara Jo Nixon , researchers from the University of Florida in Gainsveille who was not involved in the research , said the study did show an association between alcohol consumption and accelerating decline in the ability of the brain , but does not prove that alcohol was the only factor responsible . That is , there is no causal relationship between the two.
" However , studies to raise awareness for the young or middle-aged to their drinking habits , " he concluded .
