1. What is a stroke?

A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts. When this happens, part of the brain can't get blood or the oxygen it needs, so it begins to die. This kills brain cells in the area of the brain where the blockage/burst occurred.

Brain cells can't regenerate like other cells in our bodies. Once a brain cell is dead, it can't be repaired. So, early recognition is key.

2. What are the signs and symptoms of a stroke?

Signs and symptoms include:

• Sudden confusion, trouble speaking or understanding
• Sudden numbness or weakness of face, arm or leg - especially on one side of the body
• Sudden severe headache with no known cause
• Sudden trouble seeing in one or both eyes
• Sudden trouble walking, dizziness, loss of balance or coordination

It is very important to realize when you could potentially be having a stroke. Survival from a stroke is improved greatly by early detection. As soon as you recognize the signs and symptoms of a stroke call 911 immediately. The longer one waits for treatment, the more irreversible brain damage is done.

3. What are some medical conditions/factors that can increase my risk for stroke?

Some risk factors include:

• Diabetes
• Excessive alcohol use
• Family history of stroke
• High blood pressure
• High cholesterol
• Obesity
• Smoking
