The Facts
-
Every year, about 795,000 people have a stroke, according to the American Stroke Association. Roughly 600,000 are first attacks. In 2009, strokes were the third leading cause of death in the U.S. behind cardiovascular issues and cancer, with more than 143,500 people dying. More women than men die of stroke. While most strokes hit older people, young people--even children--are not immune.
Types
-
There are two types of strokes, but the result is the same--blood stops flowing to part of the brain. The more prevalent kind of strok is caused by a blockage of an artery to the brain. The other is caused by a hemorrhage of one of the vessels in the brain.

Time Frame
-
Strokes happen without warning. Typical stroke signals include weakness in the face, arm and leg, and often just on one side. The person often has difficulty speaking and may be confused. There may be a loss of balance. There may be a headache, too, although that's less common. If any of these signs are visible, call 911 immediately. Note the time the first signs developed because doctors at the hospital will need to know this information. New medical treatments are available to help stroke victims, but time is important.
Effects
-
A good way for the average person to tell whether someone is having a stroke is to look at the person's face. Both sides of our faces move together, but the face of someone who has had a stroke often droops on one side. Ask them to close their eyes and lift both arms together. Does one drift down or not lift up? Ask them to smile and see if both sides move equally. Often a stroke victim will have slurred speech or not talk. A stroke may result in other long-term effects, impacting mobility, balance and in some cases, pain. Many stroke survivors undergo rehabilitation afterwards.
Prevention/Solution
-
The risk of a stroke increases with age. Indeed, the chance of having a stroke doubles after the age of 55, according to the American Stroke Association. Strokes are more common in men than women. Some risk factors can be controlled. High blood pressure is a key factor leading to strokes. Smoking is a risk factor. Heart disease and high cholesterol also play a role. Being inactive and overweight can play a part, too.
