What is a brain infarction?
Cerebral Infarct, also known as ischemic stroke, occurs when blood vessels that give the brain are disturbed to interrupt blood flow. There are two common types of ischemic stroke: atherot communotic and embolica, as well as other less common causes. The cause of ischemic stroke cannot be determined in approximately 40% of cases.
A heart attack is a medical term that describes the necrosis that occurs when blood supply to tissues is interrupted. Blood supply can be interrupted in many ways, such as blocking the artery, mechanical artery compression by a tumor or hernia, or a rupture of artery due to trauma. Brain infarction is often associated with atherosclerosis or high blood pressure. Within minutes, a number of reactions known as an ischemic cascade begin and can continue for several hours and may even take several days. The brain is evergreen, although the supply of blood is renewed due to the possibility of reperfusion injury.
During the ischemic cascading deprivation of oxygen leads to the absence of ATP in brain tissues. ATP proton pumps fail, allowing a massive influx of calcium ions into cells. This results in the creation of reactive types of oxygen, free radicals and other harmful chemicals. Finally, the cells begin to die, some necrosis that causes an inflammatory response that can cause further damage to brain tissue. The ischemic cascade may occur in any type of tissue, but the brain is considered the most vulnerable to its complete dependence on aerobic metabolism.
Brain infarction can occur for several different reasons. The formation of thrombosis or a blood clot in an artery or blood vessel that feeds the brain can lead to interrupted blood supply. The embolism in which the porttrombosis breaks down and causes blockage is another common cause of heart attack. Cerebral venous thrombosis of sinus in which blood vessels that drain the brain may leadto a brain infarction, because blood cannot recruit in the body.
The symptoms of brain infarction are quite significant. Blowing to the brain may cause muscle weakness in the face and other parts of the body, tingling or insensitivity, inability to speak or understand speech, confusion and violations of memory. The diagnosis is usually made based on the evaluation of symptoms and neurological tests, as well as tests of medical imaging, such as CT or MRI.
The treatment of ischemic stroke may include breaking or removing thrombosis or embolus and administering drugs to prevent other clots. Much of the treatment of brain infarction is supportive in nature because many people suffer from brain tissue damage that requires rehabilitation therapy. Some people will find them Must again, how to walk, talk and perform more everyday activities, while others may have to adapt to permanent loss of such abilities.
