They compared alcohol consumption in the day, and the hour, before the beginning of stroke symptoms and their usual habits with alcohol consumption over the previous year before their stroke.
Of the total number of participants, 390 people, 64% (248) reported alcohol consumption in the previous year before their stroke. Of those 390 people, 104 reported drinking alcohol within 24 hours of their stroke and 14 within 1 hour of their stroke.
The researchers found that in the first hour after consuming alcohol people have a 2.3 times higher risk (230%) of having a stroke than do people who do not consume alcohol.
They concluded, 'The risk of stroke onset is transiently elevated in the hour after alcohol ingestion.'
During the second hour the risk was 0.6 times (60%) higher for those who had consumed alcohol.
However, after the second hour of consuming alcohol, the risk returns to its regular level of risk.
