Stroke also known as cerebrovascular accident (CVA), cerebrovascular insult (CVI), or brain attack is a medical emergency. It happens when the blood flow to the brain stop. In a minute brain cells begin to die. There are two types of strokehemorrhagic and schemic.
Hemorrhagic stroke is a brain aneurism burst or a weakened blood vessel leak. Schemic stroke is when a blood vessel carrying blood to the brain is blocked by a blood clot. The other one is called Transient Ischemic Attack (TIA) it is different from the other kind of stroke because the blood flow to the brain is only disrupted temporarily for a short period of time.
The symptoms of stroke include:
- Inability to move or feel in one side of the body
- Problem in understanding or speaking
- Loss of eyesight in one or both eye
- Difficulty in walking
- Loss of balance or coordination
- Sudden severe headache with unknown cause
Stroke occurs when the blood supply to the brain is interrupted or reduced. It may be causedby a blocked artery and leaking or bursting of blood vessel. There are also risk factors that may increase the chances of having stroke like being overweight or obesity, lack of exercise, heavy drinking, use of illicit drugs, cigarette smoking, high blood pressure, and high cholesterol. Also genetics-personal or family histories of stroke, age-55-older, race-mostly African-American and gender-men than women are factors to have higher risks of stroke.
Complication of stroke may include:
- Paralysis or loss of muscle movement
- Difficulty in talking or swallowing
- Memory loss or thinking difficulties
- Emotional problems
Certain risk factor can increase the chance of having stroke. So if you identified that you have the risk factors and symptoms for having stroke you should seek immediate medical help to reduce the risk and prevent stroke from happening to you and to others. Learn to identify your personal risk, reduce the risk factor through changing into a healthy lifestyle and medical help, and act FAST.
- Face drooping-ask the person to smile and see if the face is uneven
- Arm weakness-ask the person to raise both arms and see if one arm drift downward
- Speech difficulty-ask the person to speak a simple sentence repeatedly and see if the sentence is repeated correctly
- Time to call for help-if the person shows any of these symptoms or even if the symptoms go away call for immediate medical help. Check the time so you will know when the first symptoms appeared. Preventing a stroke is preferable to treating one.
