Aspirin Linked to Microbleeds in the Brain

A recent study conducted in the Netherlands has found out that people who regularly take aspirin have more incidences of tiny bleeding episodes in the brain.  Physicians at Erasmus MC University Medical Center in Rotterdam have come into this conclusion after analysis over 1,000 magnetic resonance imaging examination results.

Published in the online edition of Archives of Neurology, the study shows that people who are taking aspirin or carbasalate calcium, which is chemically related to aspirin, have 70 percent more chances of getting "microbleeds" compared to those who are not taking such anti-clotting drugs.  The doctors have also noted that other clot-preventing drugs such as heparin do not have the same effect on the brain.

Aspirin and carbasalate calcium are taken to reduce the risk of cardiovascular problems like heart attack and stroke as they prevent the formation of clots by acting against the platelets, the blood cell known to form clots.

Despite the link between aspirin and microbleeds, researchers are still baffled on how these tiny bursts of blood to the brain occur and how it will affect us in the future.  Some data indicate that microbleeds are associated with reduced brain function, but their role is unclear.
