For people without heart disease, a new study has shown that taking low-dose aspirin was associated with an increased risk of bleeding into the skull.
According to the study published Monday in the journal JAMA Neurology, patients with a low body mass index or Asian origin are exposed to the highest risk.
The report follows the American Heart Association's recommendation that adults over the age of 70 should not take low-dose aspirin to prevent atherosclerotic cardiovascular disease.

The researchers studied 13 clinical trials out of a total of about 134,000 patients with no history of stroke or heart disease. Those taking a placebo had a 0.46% risk of bleeding at the head during all combined tests. Those taking low-dose aspirin were at a 0.63% risk, which means that 2 out of every 1,000 people suffer from intracerebral hemorrhage.
Death and functional dependence are linked to bleeding in the skull, researchers said.
