What might an aneurysm lead to if it ruptures?

When an aneurysm ruptures, it can lead to a stroke, specifically a hemorrhagic stroke. An aneurysm is a bulge in a blood vessel caused by weakness in the vessel wall. If it bursts, it results in bleeding in or around the brain. This bleeding can lead to increased pressure on brain tissues, disruption of normal blood flow, and subsequent damage to brain cells. Symptoms of a hemorrhagic stroke can include headache, confusion, nausea, and loss of consciousness, depending on the extent of the bleeding and the areas of the brain that are affected. Overall, the rupture significantly increases the risk of a stroke, making it a critical medical emergency that requires immediate attention.
