Brain Aneurysm
A brain aneurysm, also known as a cerebral aneurysm or intracranial aneurysm, is a bulge or ballooning in a blood vessel within the brain. Imagine it as a berry hanging on a stem, but instead of a fruit, it’s a weakened area of the vessel wall. These aneurysms can form and grow due to blood flow exerting pressure on the vulnerable vessel wall. If an aneurysm leaks or ruptures, it leads to bleeding in the brain, which is a hemorrhagic stroke. Most brain aneurysms are not serious, especially if they remain small and don’t rupture. However, a ruptured aneurysm is a life-threatening emergency that requires immediate medical attention.
