• High blood pressure can damage blood vessels in the brain, increasing the chances of clots or ruptures. If a clot or rupture interferes with the flow of oxygen-rich blood to the brain, a stroke can occur.

• One in three U.S. adults has high blood pressure, and it often goes untreated. That's why it poses a major health problem - and represents a big opportunity to reduce the risk of stroke.

• The key is getting your blood pressure checked. Because high blood pressure has no obvious symptoms, checking is the only way to find out.

• Reducing blood pressure even a little - 5 to 10 mmHg - could have a big impact on your life.

• Your healthcare provider can recommend ways to lower your blood pressure, including exercise and maintaining a healthy weight.

• Medication is sometimes prescribed to treat high blood pressure, but it only works if you take it, so make sure you don't skip any doses.

• Understanding your blood pressure numbers is key to controlling high blood pressure. A normal blood pressure reading is less than 120/80 mm Hg.

• Know your numbers. Work with your doctor to determine your blood pressure goal and track your screenings.
