A study in Utah suggests a potential link between increased air pollution, specifically PM2.5 levels, and a higher risk of brain hemorrhages, with exposure possibly weakening blood vessel walls over time, though causality has not been confirmed.
A new study has found that daily, low-dose aspirin may increase the risk of brain bleeds in older adults while providing little benefit in reducing the risk of ischemic stroke. The research suggests that routine use of low-dose aspirin is not suitable for older adults without a history of heart conditions or strokes. Older individuals prone to falls, which can cause brain bleeds, should exercise caution when taking aspirin. The findings support recent guidelines advising against initiating aspirin for primary prevention in people over 70 years old. It is important for individuals to discuss the risks and benefits of aspirin use with their healthcare provider.
