Did you know that disability caused by some strokes could be prevented if treatment is given within 60 minutes? Stroke happens when blood-flow to the brain is interrupted due to blocked or burst blood vessels. Cells in the affected area begin to die because they stop getting the oxygen and nutrients they need. Stroke can lead to a range of disabilities such as paralysis, problems with thinking, problems with speaking, emotional problems, and pain or numbness. Signs of a stroke include: sudden numbness/ weakness in face, arms, or leg (especially on 1 side of body); sudden confusion, trouble speaking or understanding speech; trouble seeing in one or both eyes; trouble walking, dizziness, loss of coordination; sudden severe headache with no known cause. Because stroke affects the brain, the person having one may not realize it! So if you believe that someone is having a stroke, call 911 immediately. Every minute counts during stroke because brain cells are dying. The longer the blood flow is cut-off to the brain, the greater the damage. Immediate treatment can save lives and increase chances for successful recovery. If you have high blood pressure, you are 4-6 times more likely to have a stroke. Other risk factors include high cholesterol, diabetes, smoking, excess alcohol intake, family history of stroke, heart disease, and sickle cell disease.
