Cerebral embolism occurs when a blood clot or other debris travels through the bloodstream and lodges in a blood vessel in the brain. This blockage can restrict blood flow, leading to brain damage and potentially causing a stroke. Common sources of these emboli include the heart, especially in conditions like atrial fibrillation, where clots can form and dislodge. Symptoms of cerebral embolism can vary but often include sudden weakness, difficulty speaking, or loss of coordination. Prompt medical attention is crucial, as early treatment can help minimize damage and improve recovery chances. Understanding the risks, such as high blood pressure and high cholesterol, can aid in prevention.
