Because stroke runs in my family, I've long kept aspirin at hand--in my bag, in my car, at my desk--just in case. This study suggests that's a good idea.

From the article:
They found that almost all of the benefit of aspirin in reducing the risk of another stroke was in the first few weeks, and that aspirin also reduced the severity of these early strokes. Rather than the 15% overall reduction in longer-term risk reported previously in these trials, aspirin reduced the early risk of a fatal or disabling stroke by about 70-80% over the first few days and weeks.
