A stroke, sometimes called a "brain attack," occurs when blood flow to an area in the brain is cut off. The brain cells, deprived of the oxygen and glucose needed to survive, die. If not caught early, permanent brain damage and death can result.
"Does your bra really go up that high?" the TSA officer asked, running her hands along my chest. My boyfriend, Adam, and I were headed for a romantic getaway, and being held at airport security wasn't on our itinerary. "I have a pacemaker. That's a scar, not my bra," I said. "You're too young for that," she said.
While I'm not the only 26-year-old with a pacemaker, I'm the only one most security officers have seen. Of the pacemakers installed yearly, 84% are for people older than age 65. Only 6%...
Ischemic stroke is similar to a heart attack, except it occurs in the blood vessels of the brain. Clots can form either in the brain's blood vessels, in blood vessels leading to the brain, or even blood vessels elsewhere in the body that travel to the brain. These clots block blood flow to the brain's cells. Ischemic stroke can also occur when too much plaque (fatty deposits and cholesterol) clogs the brain's blood vessels. About 80% of all strokes are ischemic.
Hemorrhagic (heh-more-raj-ik) strokes occur when a blood vessel in the brain breaks or ruptures. The result is blood seeping into the brain tissue, causing damage to brain cells. The most common causes of hemorrhagic stroke are high blood pressure and brain aneurysms. An aneurysm is a weakness or thinness in the blood vessel wall.
What Are the Symptoms of Stroke?
The most common symptoms of a stroke are:
Weakness or numbness of the face, arm, or leg on one side of the body
Loss of vision or dimming (like a curtain falling) in one or both eyes
Loss of speech, difficulty talking, or understanding what others are saying
