The blockage of an artery in the brain by a clot (thrombosis) is the most common cause of a stroke. The part of the brain that is supplied by the clotted blood vessel is then deprived of blood and oxygen. As a result of the deprived blood and oxygen, the cells of that part of the brain die. Typically, a clot forms in a small blood vessel within the brain that has been previously narrowed due to a variety of risk factors including:
- high blood pressure (hypertension),
- high cholesterol,
- Diabetes, and
- smoking.
- ashna and sienna rox
It could also be caused by a hole in the heart which is called a PFO. Then a blood clot can go through the hole and up to the brain. I would know. It happened to me.

When do ischemic strokes occur?
Ischemic strokes occur due to blood vessels becoming blocked while hemorrhagic strokes are the result of broken blood vessels in or near the brain.
What characterizes all strokes?
they occur in the brain
What are the two strokes that occur when the piston is moving upward?
Compression/Exhaust.
What does STROKES mean?
A hemorrhagic stroke relates to your brain. Strokes can occur in large or vast amounts (small usually referred to mini stroke). Strokes all take place in the brain. Some people usually think strokes are heart related.
Which sex is most vulnerable to stroke?
two-thirds of strokes occur in people over age 65 but they can occur at any age
How many strokes occur each year?
The number of strokes that occur each year varies but estimates suggest that around 15 million people worldwide experience a stroke annually. It is one of the leading causes of death and disability globally. Improving awareness, prevention, and access to healthcare can help reduce the incidence of strokes.
What are the Causes of cerebrovascular accident?
Cerebrovascular accidents (CVAs), or strokes, can be caused by two primary mechanisms: ischemic and hemorrhagic. Ischemic strokes occur when a blood vessel supplying blood to the brain is obstructed, often due to a blood clot, atherosclerosis, or embolism. Hemorrhagic strokes arise from the rupture of a blood vessel, leading to bleeding in or around the brain, often due to high blood pressure, aneurysms, or arteriovenous malformations. Additional risk factors include diabetes, smoking, obesity, and high cholesterol.
What are three mechanisms of crustal thickening that occur at convergent boundaries?
Three mechanisms for crustal thickening are magmatic intrusion, sedimentation, and faulting.
How many power strokes occur in a eight cylinder engine in one revolution?

What does 'hemorrhagic stroke' mean?
A hemorrhagic stroke relates to your brain. Strokes can occur in large or vast amounts (small usually referred to mini stroke). Strokes all take place in the brain. Some people usually think strokes are heart related.
Evolution can occur through a variety of mechanisms. what best describes how gene flow can occur?
An individual organism moves into a new population
Are strokes hereditary?
There are inherited conditions that predispose persons to stroke, however, these are the exception rather than the rule. On general principles, strokes that occur after the age of sixty, are very unlikely to be hereditary in origin... These strokes tend to occur as a result of several "risk factors" that include high blood pressure, smoking, heart disease, diabetes and high cholesterol levels. People who have strokes at younger ages are more likely to have hereditary conditions, especially if no risk factors are identified.
