The brain requires a constant supply of oxygen, and even a brief interruption can cause irreparable damage.
World Stroke Day, October 29, offers a great opportunity to learn more about stroke risk factors, and to review appropriate response to symptoms.
“It is extremely important to know the signs of stroke and to act quickly,” said SSM Health St. Mary’s Hospital - Janesville Stroke Program Coordinator Bonnie Hemenway.
There are two types of strokes.
- An ischemic stroke happens when blood vessels in the brain are blocked.
- A hemorrhagic stroke occurs when a weakened blood vessel ruptures.
A Transient Ischemic Attack, also known as a TIA or “mini stroke,” is a temporary blockage of blood flow to the brain caused by a blood clot.
“Though TIAs can come and go without causing permanent damage to the brain, about one-third of people who experience a TIA will eventually have an ischemic or hemorrhagic stroke,” Hemenway said.
Some risk factors for stroke, like family history, cannot be controlled. However, there are many others linked to lifestyle choices.
To lower risk of stroke, be sure to:
- Control blood pressure.
- Lose weight or maintain a healthy weight.
- Exercise and focus on movement.
- Only drink alcohol in moderation.
- Avoid smoking, vaping, or using tobacco products.
- Treat atrial fibrillation appropriately.
- Control diabetes and other chronic disease.
