Taking aspirin immediately after a mini-stroke can reduce the risk of a more serious episode.
Studies have shown mini-stroke patients who are given aspirin in the hospital are 15-percent less likely to have a major stroke in the next few weeks.
But British researchers found taking aspirin within minutes of a mini-stroke can decrease the risk of a fatal or disabling stroke by 70 to 80-percent over the first few days and weeks.
Experts say anyone who has stroke symptoms should take one 300-millgram dose of aspirin while waiting for emergency care.
Researchers say doctors should give aspirin immediately if they suspect a stroke, and not wait until the patient is assessed.
