THURSDAY, June 21 (HealthDay News) -- New research may help answer the age-old question of whether factors such as the weather or drinking red wine can set off a migraine.
According to research presented this week at the annual meeting of the American Headache Society in Los Angeles, both of these factors can trigger the excruciating headaches, but not for all people and not all the time.
One small study looked at 33 adults in Brazil who considered themselves regular red-wine drinkers and believed that the beverage had caused migraines in the past. All were asked to drink half a bottle (375 milliliters) of a Malbec, Tannat, Cabernet Sauvignon and Merlot wine from South America at least four days apart.
Although most participants reported having a migraine at least once within 12 hours of drinking wine, some wines were more to blame than others -- specifically Tannat and Malbec. Both varieties contain higher levels of flavonoids known as tannins, which provide red wine's rich coloring.
Although the study was not a controlled one, conceded study lead author Dr. Abouch Krymchantowski, "I concluded that the wines with the highest content of tannins -- Tannat and Malbec -- are those which triggered migraines more frequently."
People who point to red wine as a migraine trigger but still like to drink it should choose wines with the lowest tannin content, added Krymchantowski, who is director and founder of the Headache Center in Rio de Janeiro.
"It's a small study, but it confirms what we hear from patients: Wine can trigger migraines, but not necessarily all the time," said Dr. Brian Grosberg, an assistant professor of neurology at Albert Einstein College of Medicine and co-director of the inpatient headache program at Montefiore Headache Center in New York City.
Krymchantowski would now like to see data on whether wines from different regions -- Aus
