The sudden illness that is usually caused by a blockage of blood flow to the brain is a stroke. A stroke occurs when either a blood vessel carrying oxygen and nutrients to the brain becomes blocked (ischemic stroke) or ruptures (hemorrhagic stroke). This interruption of blood flow can cause brain cells to die, leading to significant complications, including loss of abilities or even death if not treated promptly. Recognizing the signs of a stroke, such as slurred speech, weakness on one side of the body, and difficulty in understanding or forming words, is critical for timely intervention and treatment.
