Luis and Inez were playing cards one night when Luis asked Inez a question. She tried to answer but couldn't speak. Luis knew something was very wrong. Could it be a stroke? Without waiting, he called 911. The ambulance took Inez to the hospital. Emergency doctors said it was a stroke — Luis was right. Because Luis called for help quickly, Inez got the medical care she needed without delay. She started getting well, her speech came back, and once again she's having long talks with Luis.
Inez was lucky. A stroke can cause lasting physical and mental problems and even death in older people. Knowing the symptoms of a stroke and acting quickly could mean the difference between life and death. You can also take steps to lower your chance of even having a stroke.
A stroke happens when something changes how blood flows through the brain. Blood brings oxygen and nutrients to brain cells. If blood can't flow to a part of the brain, cells there could soon start to die. If brain cells are only damaged, they sometimes get better. But brain cells that have died can't be brought back to life. So, someone who has had a stroke may have trouble speaking, thinking, or walking.
There are two major types of strokes. The most common kind (ischemic) is caused by a blood clot or the narrowing of a blood vessel (artery) leading to the brain. This keeps blood from flowing into other parts of the brain and keeps needed oxygen and nutrients from reaching brain cells there. In the second major kind of stroke (hemorrhagic), a broken blood vessel causes bleeding in the brain. This break in the vessel also stops oxygen and nutrients from reaching brain cells.
Call 911 RIGHT AWAY if you see or have any of these symptoms:
DON'T IGNORE THE SIGNS OF STROKE!
Never ignore the symptoms of stroke. Call 911 if you have any stroke symptoms, even if they don't last long.
Sometimes the symptoms of a stroke last only a few minutes and then go away. That could be a TIA (transient ischemic attack), also called a mini-stroke. A TIA is a medical emergency. You should get medical help right away. If a TIA is not treated quickly, it could be followed within hours or days by a major disabling stroke.
The doctor will diagnose a stroke based on symptoms, medical history, and medical tests, like a CT scan. A CT scan is a kind of test that lets doctors look closely at pictures of the brain.
All strokes benefit from immediate medical treatment! But, only people with ischemic stroke, the kind caused by a clot, can be helped by a drug called t-PA (tissue-plasminogen activator). This drug breaks up blood clots and can greatly lessen the damage caused by an ischemic stroke. Starting treatment with the drug t-PA within 3 hours after an ischemic stroke is key to recovery. Getting to a hospital right away allows time for a CT scan of the brain. This scan will show whether this clot-busting medicine is the right treatment choice.
A stroke can cause a variety of health problems. Someone who has a stroke might be paralyzed or have weakness, usually on one side of the body. He or she might have trouble speaking or using words. There could be swallowing or memory problems. Someone who has had a stroke might feel depressed or find it hard to control emotions. There might be pain or numbness.
There are many different ways to help people get better after a stroke. Many treatments start in the hospital and continue at home. Drugs and physical therapy can help improve balance, coordination, and some problems such as trouble speaking and using words. Occupational therapy can make it easier to do things like taking a bath or cooking.
A family doctor can provide follow-up care. Some people make a full recovery soon after a stroke. Others take months or even years. But, sometimes the damage is so serious that therapy cannot really help.
Talk to your doctor about what you can do to lower your risk of stroke. Even if you're in perfect health, follow these suggestions:
