Cerebrovascular Disease
February 10th 2010 05:45
Lately I have been seeing a tremendous number of individuals suffering from stroke.
Cerebrovascular disease or more popularly known as stroke, has been a major killer worldwide. But what is this condition and what causes it?
stroke is a condition delineated by lesion in the brain cells, caused by hemorrhage or occlusion of blood vessels going to the brain.
Blood transports oxygen and nutrients to the different parts of the body. it also removes waste products from every cells, including the brain cells. But once blood becomes viscous, or the vessels become too narrow for blood to effectively flow, waste products from the cells cannot be removed and these will damage the cells. No oxygen, nor glucose can be delivered to the cells for nourishment. Eventually these cells die. Unlike the skin cells, the brain cells are more of a permanent type. No replacement for these cells. And this for sure can affect a person's movement, sensation, and other functions.
What can lead to such conditions? Increased blood cholesterol, atherosclerosis, hypertension. Risk factors include smoking, sedentary lifestyle, poor eating habit (fatty diet), diabetes mellitus, and others.
Hemorrhage caused by trauma, or by ruptured blood vessels (like in aneurysm) in turn can also cause stroke. The cranial cavity or the place where the brain is located is a space exclusively for the brain. The size just fits for the brain and its nearby complementary structure. If hemorrhage ensues, the space gets crowded, impinging or compressing the brain cells. Markers of which are headache, increased intracranial pressure, vomitting, dizziness, to name a few.
