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.
I had no inkling I had heart disease until December 2005, when I had two minor episodes of mild angina (pain in the chest area). My primary care physician ran an electrocardiogram but saw nothing abnormal. I was an athletic, lean 53-year-old who ate nutritious foods. He decided I was just stressed and gave me the go-ahead to go to Nicaragua on vacation.
But while there, the angina went from mild to severe. The pain would come and go, but on three separate occasions the pain was the most massive...
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
