Risk increases with more years of drinking.
People in their 20s and 30s who drink moderate to heavy amounts of alcohol may be more likely to have a stroke as young adults than people who drink low amounts or no alcohol, according to a study published in the November 2, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology. The risk of stroke increased the more years people reported moderate or heavy drinking.

“The rate of stroke among young adults has been increasing over the last few decades, and stroke in young adults causes death and serious disability,” said study author Eue-Keun Choi, MD, PhD, of Seoul National University in the Republic of Korea. “If we could prevent stroke in young adults by reducing alcohol consumption, that could potentially have a substantial impact on the health of individuals and the overall burden of stroke on society.”
The study looked at records from a Korean national health database for people in their 20s and 30s who had four annual health exams. They were asked about alcohol consumption each year. They were followed for an average of six years.
They were asked the number of days per week they drank alcohol and the number of standard drinks per time. People who drank 105 grams or more per week were considered moderate or heavy drinkers. This is equal to 15 ounces per day, or slightly more than one drink per day. A standard drink in the United States contains about 14 grams of alcohol, which is equivalent to 12 ounces of beer, five ounces of wine or 1.5 ounces of liquor.
