The most common cause of brain infarction is stroke, which is when blood supply to the brain is interrupted. A ischemic stroke occurs when a blood vessel carrying blood to the brain is blocked by a blood clot. A hemmorhagic stroke occurs when a blood vessel breaks open, causing blood to leak into the brain. The risk of stroke increases with high blood pressure, age, family history, smoking, Heart disease, Diabetes, and high cholesterol. Drug and alcohol abuse, bleeding disorders, and head injuries can also cause bleeding into the brain.

What is the reason for hemiparesis?
There is infarction or hemorrhage (bleeding) in the internal capsule area of the brain. Which causes hemiparesis in opposite side of the body.
Can trauma cause an infarct in the brain?
Yes. Infarction is a state of tissue death due to no blood supply to that area. A trauma to any area of the body can cause the obstruction of blood flow to that area, hence causing an infarction. Though the brain is heavily protected, brain infarction can occur.
What is Cerebral-infarcts?
Cerebral infarction (CI) is a severe condition caused by a focal vascular occlusion in an area of the brain. This causes an area of destruction resulting from a lack of oxygen delivery.
What is acute infarction?
Bone infarct refers to ischemic death of the cellular elements of the bone and marrow.
What causes pseudobulbar palsy?
causes of pseudobulbar palsy are as following: 1- Vascular diseases; Bilateral Hemisphere Infarction. 2- Degenerative disorders ; Motor neuron disease 3-Inflammatory disorders ; Multiple sclerosis 4-Malignancy ; High brain stem tumor 5-Brain trauma
What are brain?
"Infarction" is a medical term for tissue damage due to occlusion of an artery supplying that tissue. It can apply to any tissue, a renal infarction being damage to some part of a kidney in this way. One only hears the term commonly, though, for the heart and the brain. A myocardial infarction is damage to heart muscle, the myocardium. This is what's commonly called a heart attack. An infarction of the brain is damage to brain tissue from lack of blood supply from a single artery, called "ischemia", the most common form of what is commonly called a stroke. Infarction of the brain is divided into damage to the cerbral cortex, called "cerebral infarction" and damage to the lower parts of the brain, called "brainstem infarction". The former is generally supplied by the carotid arteries while the latter is supplied by the vertebral arteries. Infarction can occur due to thrombosis, in which an artery closes off due to atherosclerosis, or embolism where a blood clotor other material travels to an artery feeding the brain, usually from the heart. The artery causing the infarction may remain occluded or may clear,but still having been occluded long enough to cause infarction. Symptoms of brain infarction depend on the location of the tissue damaged. They may include weakness, inability to speak, reduced vision, double vision, dizzyness, imbalance, altered sensation or confusion. The best treatment of brain infarction depends on patients presenting to the emergency room within3 hours of such symptoms, the sooner the better. Recovery from brain infarction depends on how reversible the damage to the brain tissue is. Many small infarctions improve over weeks to months. Old, small infarctions may be discovered on CT or MRI scans, apparently having occurred in the past without symptoms. Large infarctions may cause patients considerable symptoms, which may still be improving at least two years after the stroke.
Why are you extremely thirsty after myocardial infarction?
After an attack (myocardial infarction), the patient is in shock. This causes a fluid shift, thus making the patient thirsty.
What is a capsular infarction?
A stroke, "infarction", in the capsule area of the brain. This often results in a loss of motor functions. The motor function affected depends on the location of the lesion in the capsule.
What is the result of brain infarct on human?
When an infarction happens in the brain that is known as a cerebral vascular accident or more commonly known as a stroke.
What causes infarction?
The supplying artery can be blocked by an obstruction, mechanically compressed, ruptured by trauma, or vasoconstricted.
How would myocardial infarction affect cardiac output?
A myocardial infarction is a heart attack; during this, the heart's beat effectively stops and the heart is no longer pumping blood in any useable amount. Therefore, a myocardial infarction causes cardiac output to drop significantly and possibly drop to zero depending on the severity.
What is Cerebellum Infarct?
Cerebellum Infarct or infarction is a clot of an artery in the brain. The cerebellum is the part of the brain which coordinates muscle movement. Infarction is a medical condition in which tissue dies because the arterial blood supply is blocked. This basically means a stroke (from what i have read and been told). This is a more understandable version. to find out more contact you're GP.
