An overview of intracranial aneurysms
Overview
Paper Summary
Intracranial aneurysms, though common (affecting ~4% of people), mostly don't cause symptoms and rarely rupture. The rupture risk is size-dependent, with larger and posterior circulation aneurysms being more dangerous. The preferred management approach is observation for small (<7mm) anterior circulation aneurysms in asymptomatic patients, with endovascular coiling or surgical clipping considered for other cases.

Scientists found that tiny balloons can form on blood vessels in your brain. Most people who have them are fine, but doctors watch the bigger ones carefully or fix them so they don't pop.

Rating Explanation
This review paper provides a useful overview of intracranial aneurysms, but several limitations prevent a higher rating. The reliance on studies with small sample sizes, rapid advancements in imaging technology, and the ongoing debate surrounding the natural history of these aneurysms (particularly the controversy around the ISUIA findings) all impact the strength of the conclusions. While it effectively summarizes existing knowledge, it does not present groundbreaking new research or offer definitive answers regarding management.
