Fact 3: The Underlying Causes of Cerebrovascular Disease
The causes of cerebrovascular disease are diverse, reflecting the multifaceted nature of this condition. Some people may be surprised to learn that underlying diseases like atherosclerosis – the buildup of fats, cholesterol, and other substances in the artery walls – are prime suspects. This buildup, known as plaque, can limit or block the blood flow to the brain, leading to a stroke.
Next, let’s talk about embolisms. An embolism occurs when a blood clot or other particle forms in a blood vessel away from the brain, often in the heart or neck. These clots can travel through the bloodstream and lodge in narrower brain arteries, causing a stroke.
Intracranial artery disease, where the arteries within the brain narrow or become blocked, is another culprit. This condition can lead to a stroke due to reduced blood flow or the formation of clots in the affected arteries.
Another important cause to highlight is aneurysms, which are weak, bulging spots on the wall of a brain artery. While many aneurysms don’t rupture or create health problems, a ruptured aneurysm quickly becomes life-threatening and requires prompt medical treatment. (3)
