A brain aneurysm is a bulge in a blood vessel. It can resemble a berry hanging from a stem. Aneurysms can rupture, causing bleeding in the brain, which can be life-threatening. In most cases, a person does not even know he or she has a brain aneurysm, as they don’t cause any symptoms; a doctor usually discovers an aneurysm while testing for other conditions.
The main symptom of a ruptured brain aneurysm is a sudden and excruciating headache. Some people also experience nausea, vomiting, confusion, loss of consciousness, light sensitivity, stiff neck, blurred vision, and seizures. A ruptured brain aneurysm is extremely dangerous, so it is vital to receive medical care as quickly as possible after symptoms begin.
