Acute Stroke Definition and Symptoms

Acute stroke refers to a stroke that happens very suddenly. Doctors also use the term “acute” to refer to a stroke that occurred very recently (within hours). A stroke is when blood supply to the brain is cut off because of a blood clot that has blocked a blood vessel and can be extremely dangerous. Symptoms of a stoke are numbness in the left side of the body, double vision, slurred speech, hearing loss, dizziness, imbalance, and falling.
