Age increases the risk because the walls of blood vessels gradually lose elasticity and accumulate damage. However, aneurysms can also develop at a younger age due to genetic predisposition, connective tissue disorders (such as Ehlers-Danlos syndrome), or congenital vascular weakness. Lifestyle factors, especially smoking and uncontrolled hypertension, accelerate vascular damage regardless of age.
Myth 2: “If there are no symptoms, it is not dangerous.”
Fact: Many aneurysms are asymptomatic until they rupture.
Science:
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.
