Cerebral infarction occurs when blood flow to a part of the brain is blocked, leading to tissue damage. This blockage can be caused by a blood clot or a narrowing of the blood vessels, often related to conditions like atherosclerosis or atrial fibrillation. The affected brain cells begin to die due to a lack of oxygen and nutrients. Symptoms of cerebral infarction can include sudden weakness, difficulty speaking, and loss of coordination. Prompt medical attention is crucial, as early treatment can help minimize brain damage and improve recovery outcomes. Rehabilitation may be necessary to regain lost functions after the event.
