Fast action is key when suffering a stroke
August 31, 2021
Every 40 seconds, a person in the United States suffers a stroke, making it the fifth-leading cause of death. However, these life-threatening, medical emergencies are preventable and can be treated. It’s important to be aware of stroke risk factors and symptoms to stay healthy and minimize risks.
A stroke occurs when blood supply to the brain is interrupted or reduced. While there are three main types of strokes that can occur, more than 80% of them are categorized as ischemic stroke – those caused by blocked or narrowed arteries that severely reduce blood flow. A hemorrhagic stroke occurs when blood vessels in the brain leak or rupture. And a transient ischemic attack, or a ministroke, is due to a temporary decrease in blood to the brain. While strokes often lead to serious long-term disability, a transient ischemic attack typically does not create permanent damage.
There are a number of lifestyle and medical factors that can cause a stroke. The leading causes include:
- High blood pressure
- High cholesterol
Americans are at high risk for stroke, with 1 in 3 adults having at least one of the leading causes. Other factors include:
- Heart disease, including atrial fibrillation
- Sex hormones
- Obstructive sleep apnea
- Advancing age
- Minority race-ethnicity
In Chicago, we know that stroke hits hardest in the African American and Latinx communities. An important way to prevent stroke is to improve blood pressure control, exercise and eating habits, especially in high-risk groups.
According to the Centers for Disease Control and Prevention, the risk of having a first stroke is nearly twice as high for Blacks as it is for whites. And while death rates from stroke have declined among all races, African Americans continue to have the highest rate of death due to stroke. Meanwhile, Hispanics have seen an increase in death rates due to stroke since 2013.
When seeking treatment, the faster one can receive medical treatment, the better the outcome. That’s why it’s important to be aware of the following symptoms:
- Sudden numbness or weakness in the face, legs or arms (usually one-sided)
- Confusion or trouble speaking or understanding others
- Severe headache – the worst of your life
The signs and symptoms of a stroke can vary from person to person. The symptoms can also evolve from one symptom to another in the same patient. When feeling or witnessing the signs of a stroke, it is important to act quickly, and call 911 even if the symptoms are temporary.
