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.

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.

Stroke is caused when there is a blockage in the brain. It is essentially like having a heart attack in your brain. A blockage occurs somewhere in the brain, cutting off blood and oxygen to an area of the brain causing that area to die.
A stroke occurs when blood flow is interrupted to part of the brain. Without blood to supply oxygen and nutrients and to remove waste products, brain cells quickly begin to die. Depending on the region of the brain affected, a stroke may cause speech impairment, loss of memory and reasoning ability, or death. A stroke is also sometimes called a brain attack or a cerebrovascular accident (CVA). # Avoid such diseases by maintaining a healthy lifestyle including regular exercises.
There are two main types of stroke. One is called an Occlusive stroke which means that the blood vessel in the brain is blocked, usually by a blood clot. The other type of stroke is called a Hemorrhagic (pronounced hemoragic) stroke where the blood vessel in the brain bleeds uncontrollably.
Strokes are caused by a disruption of blood supply to the brain, often a blood clot.

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.
What are three mechanisms of crustal thickening that occur at convergent boundaries?
Three mechanisms for crustal thickening are magmatic intrusion, sedimentation, and faulting.
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.
How many power strokes occur in a eight cylinder engine in one revolution?
44
Evolution can occur through a variety of mechanisms. what best describes how gene flow can occur?
An individual organism moves into a new population
What are the 4 mechanisms by which evolution can occur?
genetic drift, mutation, natural selection, and migration
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.
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.
