 THURSDAY, Jan. 29, 2015 (HealthDay News) -- Too much alcohol in middle age can increase your stroke risk as much as high blood pressure or diabetes, a new study suggests. 
  
 People who average more than two drinks a day have a 34 percent higher risk of stroke compared to those whose daily average amounts to less than half a drink, according to findings published Jan. 29 in the journal Stroke. 
  
 Researchers also found that people who drink heavily in their 50s and 60s tend to suffer strokes earlier in life than light drinkers or non-imbibers. 
  
 "Our study showed that drinking more than two drinks per day can shorten time to stroke by about five years," said lead author Pavla Kadlecova, a statistician at St. Anne's University Hospital International Clinical Research Center in the Czech Republic. 
  
 The enhanced stroke risk created by heavy drinking rivals the risk posed by high blood pressure or diabetes, the researchers concluded. By age 75, however, blood pressure and diabetes became better predictors of stroke. 
  
 The study involved 11,644 middle-aged Swedish twins who were followed in an attempt to examine the effect of genetics and lifestyle factors on risk of stroke. 
  
 Researchers analyzed results from a Swedish registry of same-sex twins who answered questionnaires between 1967 and 1970. By 2010, the registry yielded 43 years of follow-up, including hospital records and cause-of-death data. 
  
 Almost 30 percent of participants had a stroke. They were categorized as light, moderate, heavy or nondrinkers based on the questionnaires, and researchers compared the risk from alcohol and health risks such as high blood pressure, diabetes and smoking. 
  
 The researchers found that for heavy drinkers, alcohol produced a high risk of stroke in late middle age, starting at age 50. By comparison, light drinkers' or nondrinkers' stroke risk increased gradually with age. 
  
 Among identical twins, siblings who had a stroke drank more than their siblings who hadn't had a stroke, suggesting that midlife drinking raises stroke risks regardless of genetics and early lifestyle, the researchers said. 
  
 Midlife heavy drinkers -- those in their 50s and 60s -- were likely to have a stroke five years earlier in life, irrespective of genetic and lifestyle factors, the study found. 
  
 The findings are consistent with national guidelines that recommend a maximum of two drinks a day for men and one for women, said Dr. Irene Katzan, a staff neurologist and director of the Center for Outcomes Research and Evaluation at the Cleveland Clinic. That translates to a daily maximum of about 8 ounces of wine for a man and 4 ounces for a woman. 
  
 "It's a nice study that corroborates what we've known about alcohol and stroke, and it corroborates the recommendations that are in the national guidelines," Katzan said. 
  
 It's not clear exactly how alcohol affects stroke risk, but some theories center on the fact that alcohol thins your blood. This could increase your risk of hemorrhagic stroke, in which a blood vessel breaks inside the brain, Katzan said. 
  
 "The more you drink, the more risk you have of bleeding in the brain," she said. 
  
 At the same time, it's also well-known that alcohol contributes to high blood pressure and can increase the chances of atrial fibrillation, two other health-related risk factors for stroke, she added. 
  
 "Who knows what combination of factors are at play in any particular person?" Katzan concluded. 
  
 People who imbibe should consider cutting back their intake if they are having two or more drinks a day on average, Katzan and Kadlecova said. 
  
 "It is okay to drink in moderation," Katzan said. "The ideal is consuming less than two drinks per day for men, and for non-pregnant women the maximum should be no more than one drink per day."

 Background and Purpose—Although alcohol–stroke association is well known, the age-varying effect of alcohol drinking at midlife on subsequent stroke risk across older adulthood has not been examined. The effect of genetic/early-life factors is also unknown. We used cohort and twin analyses of data with 43 years of follow-up for stroke incidence to help address these gaps. 
  
 Methods—All 11 644 members of the population-based Swedish Twin Registry born 1886 to 1925 with alcohol data aged ≤60 years were included. The interaction of midlife alcohol consumption by age at stroke was evaluated in Cox-regression and analyses of monozygotic twins were used. Covariates were baseline age, sex, cardiovascular diseases, diabetes mellitus, stress reactivity, depression, body mass index, smoking, and exercise. 
  
 Results—Altogether 29% participants developed stroke. Compared with very-light drinkers (<0.5 drink/d), heavy drinkers (>2 drinks/d) had greater risk of stroke (hazard ratio, 1.34; P=0.02) and the effect for nondrinkers approached significance (hazard ratio, 1.11; P=0.08). Age increased stroke risk for nondrinkers (P=0.012) and decreased it for heavy drinkers (P=0.040). Midlife heavy drinkers were at high risk from baseline until the age of 75 years when hypertension and diabetes mellitus grew to being the more relevant risk factors. In analyses of monozygotic twin-pairs, heavy drinking shortened time to stroke by 5 years (P=0.04). ||||| You may want to keep that third beer of the night stashed in your fridge. 
  
 People in their 50s and 60s who down more than two alcoholic beverages daily have a 34 percent higher risk of stroke compared to lighter drinkers — and are more apt to suffer a stroke five years earlier in life regardless of their genetics or their other health habits, asserts a study released Thursday. 
  
 In fact, sipping beyond a two-drink maximum each day may boost a middle-aged person's stroke risk more than even traditional health dangers like high blood pressure and diabetes, say researchers who base their findings on tracking more than 11,000 Swedish twins for roughly half their lives. 
  
 "We are seeing more and more people who are having strokes at younger ages and we don't necessarily appreciate how much alcohol use may be contributing to that," said Dr. Shazam Hussain, head of the Cleveland Clinic stroke program. He is not associated with the study, which was published in the American Heart Association journal Stroke.

 The rise in strokes among increasingly younger patients, as documented by doctors at the Cleveland Clinic, has long been linked to more modern Americans being diagnosed earlier with high blood pressure, diabetes or obesity, Hussain said. But the new, alcohol-consumption finding gives physicians another potential risk factor to monitor. 
  
 Will Hussain advise his patients to always call it a night after two cocktails? Not quite yet. There's too much conflicting science, he said, on how many sips of wine a night may be beneficial versus how many glasses of wine may be harmful over the span of many years. 
  
 "We know that the more you drink, the worse off you're going to be. Whether no alcohol versus a little bit of alcohol is any different, that's tough to say," Hussain said. "I'm a little hesitant to just recommend anything particularly about drinking." 
  
 Knocking back more than two drinks per day was defined by the study's authors as "heavy" drinking — certainly, a subjective term for some Americans. But those findings are consistent with the American Heart Association's recommended limit of two drinks a day for men and one for women. That's equals about eight ounces of wine (two drinks) for a man and four ounces (one drink) for a woman. 
  
 The scientists drew that hard line at three or more daily drinks by dissecting the lifestyle choices and health accounts of 11,644 middle-aged twins who were followed for 43 years as part of the the Swedish Twin Registry. Participants answered questionaries for several years. All were under 60 when they joined the registry. Almost 30 percent of participants suffered a stroke. 
  
 At about age 75, blood pressure and diabetes seemed to re-emerge the main influences on having a stroke, researchers said. 
  
 "This study ... is extremely interesting, because they were able to follow these people for a long period of time. It was done in twins, which allows you to eliminate a lot of factors," said Dr. Demetrius Lopes, a neurosurgeon and director of cerebrovascular surgery at Rush University Medical Center in Chicago. 
  
 "The question is: How much is too much alcohol? ... The amount defined as 'heavy drinking' doesn't mean you're drunk every day," Lopes said. 
  
 In fact, many Americans with a European heritage routinely have some wine with dinner every night, Lopes said. 
  
 "But it's important to be aware that it's not as benign as we thought. Its protective range is only within the two drinks for men and one for women. That range is definitely not harmful, and some studies have even shown protective effect at this level of drinking. 
  
 "This study points to the importance of the upper limit of alcohol," Lopes added. "It is a misconception that if a glass of red wine is good, more is even better. That's a fine balance." |||||

Looking forward to kicking back a few beers during the Super Bowl? And on Saturday? And tonight? Here's some news that could give those who have more than two drinks a day on a regular basis pause. Using 43 years of data on 11,644 same-sex Swedish twins, researchers report in the American Heart Association journal Stroke that "heavy" drinking raises one's risk of stroke as much as diabetes and high blood pressure. And it didn't take much to reach the "heavy" label, defined as exceeding two drinks a day. Those who average more than two daily saw a stroke risk 34% higher than those who averaged less than half a drink a day, reports HealthDay News. "Our study showed that drinking more than two drinks per day can shorten time to stroke by about five years," the lead author said. This was true regardless of genetic and other lifestyle factors. "It's important to be aware that [drinking is] not as benign as we thought," a neurosurgeon not involved in the study tells NBC News. "Its protective range is only within the two drinks for men and one for women." It remains unclear precisely how alcohol increases one's risk of stroke, but alcohol is known to elevate blood pressure and thin blood; the latter could up the risk of hemorrhagic stroke.
