Information on Strokes
Known medically as a cerebrovascular accident or CVA, a stroke is an episode that occurs suddenly and can cause lasting damage to the brain. It occurs when blood supply to part of the brain is interrupted or when a blood vessel in the brain bursts, spilling blood into the spaces surrounding brain cells. Things that increase your risk for a stroke include having high blood pressure, smoking, and having a family history of a stroke.
Symptoms of a stroke most often appear suddenly, and it is not uncommon for multiple symptoms to occur at the same time. Symptoms often include trouble walking, dizziness, confusion, difficulty seeing, and numbness or weakness in the limbs or face.
If you are experiencing symptoms of a stroke, do not wait to see if they improve or get worse before getting help. Delaying treatment can result in lasting damage to your brain, or even death. A stroke is a medical emergency. The sooner you get treatment, the better your chance of recovery.
