Small or stable aneurysms often do not compress nearby structures and therefore do not cause symptoms. However, the arterial wall at the site of the aneurysm is structurally weakened. Over time, hemodynamic stress (the force of blood flow) can further thin the wall. When the wall fails, a rupture can occur, causing internal bleeding, such as a subarachnoid hemorrhage in the brain, which is a medical emergency.
Myth 3: “A headache is just a headache.”
Fact: A sudden, severe headache may indicate a ruptured brain aneurysm.
Science:
Patients often describe it as “the worst headache of my life.” This pain is caused by the rapid irritation of the meninges (the brain’s protective membranes) by blood. It may be accompanied by nausea, neck stiffness, sensitivity to light, or fainting. This is not a common tension headache or migraine; it requires immediate emergency medical attention.
Myth 4: “Healthy people have nothing to worry about.”
Fact: You can have an aneurysm even if you look healthy.
Aneurysms can develop silently due to microscopic changes in the arterial wall, such as inflammation, collagen degradation, and alterations in blood flow. Even in seemingly healthy individuals, factors such as chronic stress, undiagnosed hypertension, or a family history of aneurysms can contribute to their formation and growth.
Myth 5: “All aneurysms rupture.”
Fact: Not all aneurysms rupture, but the risk varies.
Science:
The risk of rupture depends on the size, location, growth rate, and integrity of the arterial wall. For example, larger aneurysms or those located in certain cerebral arteries are more likely to rupture. Doctors may recommend monitoring with imaging tests or preventive treatment (such as surgical clipping or endovascular embolization) based on an individualized risk assessment.
