Stroke Awareness and Prevention Quiz 2017

According to the National Stroke Association, strokes cannot be prevented. True or False?

 

False - According to the National Stroke Association, up to 80 percent of strokes can be prevented. To prevent stroke, start by getting regular exercise, eating a healthy diet, maintaining a healthy weight and not smoking. Also:

  • Have your blood pressure checked regularly.
  • Report any episodes of missed or irregular heartbeats.
  • Find out if you have high cholesterol.
  • Treat circulation problems such as blocked arteries, sickle cell disease and severe anemia.
Anyone can have a stroke, although certain stroke risk factors increase the chance:
  • High blood pressure (greater than 140/90 for people without diabetes or greater than 130/80 for people with diabetes)
  • Cigarette smoking
  • Diabetes and uncontrolled blood sugar
  • Heart disease and/or irregular heartbeat
  • Sickle cell disease
  • High cholesterol
  • Obesity, poor diet and physical inactivity

Some stroke risk factors cannot be changed:

  • Age - The risk of stroke doubles for every decade after 55
  • Family history of stroke in a parent, grandparent, sister or brother
  • Previous stroke or TIA
  • Sex - Men have a higher risk at younger ages, while women have a higher risk over 85
  • Race/ethnicity

Hispanics have a higher risk of stroke than other races. True or False?

 

False - According to the Centers for Disease Control and Prevention (CDC), African Americans, American Indians and Alaska Natives are more likely to have a stroke than are other groups. The risk of having a first stroke is nearly twice as high for blacks as for whites, while Hispanics’ risk for stroke falls between that of whites and blacks.

It’s critical that a stroke victim receive evaluation and proper treatment quickly to minimize injury to brain tissue. True or False?

 

True - Call 911, if you suspect these signs of a stroke:

  • Sudden weakness or numbness of the face, arm or leg, usually on one side of the body
  • Sudden dimness or loss of vision, particularly in one eye
  • Loss of speech, or trouble talking or understanding speech
  • Sudden severe headache with no apparent cause
  • Sudden episodes of difficulty walking or unexplained dizziness or unsteadiness; especially in combination with any of the previously noted symptoms

Other less common symptoms of stroke may include sudden nausea or vomiting, fainting, confusion, seizures, or coma. A transient ischemic attack (TIA), or “mini-stroke,” may also occur. TIAs may be warning signs of stroke about to occur.

Stroke victims show different symptoms, depending on the type of stroke (ischemic stroke or hemorrhagic stroke), where exactly the stroke occurs in their brain, and how acute the bleeding is. Stroke symptoms happen suddenly and simultaneously, but not all symptoms may occur.

Although strokes are usually sudden attacks, strokes also can occur over hours, or several small strokes can occur over time. Symptoms then build in intensity as the stroke becomes more acute.

Always take note of what time the stroke victim begins showing symptoms and call 911 immediately. It takes only a few seconds for the brain to stop functioning when a stroke causes a brain hemorrhage. The faster a stroke victim is treated, the less devastating the effects will be.

About 55,000 more strokes occur in women than men in the United States every year. True or False?

 

True - Stroke is the third leading cause of death for women and the fifth leading cause for men. On average, one in five women has a stroke, and about 55,000 more strokes occur in women than men in the United States every year. Several stroke risk factors are hormonal and unique to women, including pregnancy, oral birth control pills and hormone replacement therapy.

Some other stroke factors tend to be more common in women as well, such as atrial fibrillation, depression, diabetes, cerebral vein thrombosis and migraine headaches. Women also tend to live longer than men, giving them a longer time to be at risk for a stroke.

If a woman is taking oral birth control pills and has high blood pressure or smokes, her risk of suffering a blood clot and/or stroke increases significantly. Middle-aged women are also at a higher risk than younger women when taking birth control pills.

One high-risk stroke factor in pregnant women is the risk of preeclampsia (a blood pressure disorder during pregnancy). Women with high-blood pressure who become pregnant should take extra precautions and consult their physician about preventing preeclampsia and stroke. If a woman has preeclampsia, she is twice as likely to suffer a stroke. Preeclampsia is also a lifelong risk factor because it causes women to be four times more likely to have high blood pressure later in life.

Although hormone replacement therapy was previously thought to lower stroke risk, it actually increases the risk for a stroke.

Specific stroke risks in women also vary throughout life, depending on the time of pregnancies and menopause.

Ischemic stroke, in which blood flow to the brain is blocked, is the most common type of stroke. True or False?

 

True - The three main types of stroke are ischemic stroke, hemorrhagic stroke and transient ischemic attack (TIA).

Most strokes (87 percent) are ischemic strokes. An ischemic stroke happens when blood flow to the brain becomes blocked. Blood clots often cause the blockages that lead to ischemic strokes.
A hemorrhagic stroke happens when an artery in the brain leaks blood or ruptures (breaks open). The leaked blood puts too much pressure on brain cells, which damages them. High blood pressure and aneurysms — balloon-like bulges in an artery that can stretch and burst — are examples of conditions that can cause a hemorrhagic stroke.

A transient ischemic attack (TIA) is sometimes called a "mini-stroke." It’s different from the major types of stroke because blood flow to the brain is blocked for only a short time — usually no more than five minutes. As with ischemic strokes, blood clots often cause TIAs.

It’s important to note that a TIA is a warning sign of a future stroke. More than a third of people who have a TIA and don’t get treatment have a major stroke within a year, and as many as 10-15 percent of people will have a major stroke within three months of a TIA.

Recognizing and treating TIAs can lower the risk of a major stroke. If you have a TIA, your health care team can find the cause and take steps to prevent a major stroke. Strokes and TIAs require emergency care. Call 911 right away if you feel signs of a stroke or see symptoms in someone around you.
