Embolic cerebral artery strokes are a type of stroke that occurs when a blood clot or debris travels through the bloodstream and gets stuck in one of the arteries in the brain. This blockage can lead to a lack of oxygen and nutrients reaching parts of the brain, causing damage and various symptoms. In this article, we’ll break down the key aspects of embolic cerebral artery strokes in simple language, making it easier to understand.
Embolic cerebral artery strokes, often called embolic strokes for short, are a type of ischemic stroke. Ischemic strokes occur when blood flow to the brain is disrupted due to a blockage in one of the arteries. In the case of embolic strokes, the blockage is caused by an embolus, which is a clot or debris that travels through the bloodstream and becomes lodged in a blood vessel within the brain.
Types of Embolic Cerebral Artery Strokes:
- Cardioembolic Stroke: This type of stroke is caused by a clot that forms in the heart and travels to the brain. It often occurs in individuals with conditions like atrial fibrillation (an irregular heartbeat) or heart valve problems.
- Paradoxical Embolism: In this type, a clot from a vein, usually in the legs, crosses over into the arterial circulation and reaches the brain.
Now that we have an understanding of what embolic cerebral artery strokes are and their types, let’s explore the causes, symptoms, diagnosis, treatment options, and medications in plain English.
Causes of Embolic Cerebral Artery Strokes
- Atrial Fibrillation: Irregular heartbeats can lead to the formation of clots in the heart, increasing the risk of stroke.
