When a clot forms elsewhere, breaks free, and then lodges in the brain, this is known as:

The situation described in the question refers to an embolic stroke, which occurs when a blood clot (an embolus) originates in another part of the body—often the heart or large arteries—and travels through the bloodstream until it lodges in a blood vessel in the brain, obstructing blood flow. This obstruction can lead to brain damage due to insufficient oxygen and nutrients reaching the affected area.

Embolic strokes are specifically characterized by the fact that the clot is formed elsewhere and travels to the brain, distinguishing them from other types of strokes such as thrombotic strokes, which are caused by clots that form directly in the blood vessels of the brain due to plaque buildup. Understanding these distinctions is crucial for accurately diagnosing the type of stroke, determining the appropriate treatment, and predicting outcomes for patients.
