Stroke also known as cerebrovascular accident (CVA), cerebrovascular insult (CVI) or brain attack. A brain seizure is the loss of brain function due to disruption of blood supply to the brain. This disruption is due to one of two causes: ischemia (lack of blood flow) or hemorrhage (large increase in blood flow directly into the brain; parenchyma or subarachnoid space that surrounds the brain of tissues). Ischemia is the formation of a blood clot located inside a blood vessel located in the circulatory system, called thrombosis or arterial embolism; it is a rapid interruption of blood supply to an organ or part of the body due to a clogged artery blocking blood flow. Thrombosis is a medical condition in which the brain experiences a lack of blood and oxygen supply to the organ called cerebral hypoperfusion. The result of an uncontrolled stroke can cause permanent neurological damage or even death. Some possible risk factors for stroke are old age, previous stroke, transient ischemic attack (TIA), diabetes, smoking, high cholesterol, and high blood pressure, which is the contributing factor. most common risk of stroke. The four types of stroke are ischemic stroke, transient ischemic stroke (TIA or minor stroke), hemorrhagic stroke, and pediatric stroke. A stroke is usually linked to the brain, one of the most complex organs in our body, made up of 100 billion specialized nerve cells called neurons. The neurons in our body feed on the oxygen and nutrients found in the blood. When a person suffers a stroke, the functions affected depend on the extent and cause of the damage present. Brain damage then varies from one individual to another. The parts affected by a stroke depend on the area of ​​brain injury... middle of paper ...... anticoagulant medications) and medications to lower cholesterol (cholesterol absorption inhibitors, Fabrates, Niacin, Resins, etc.) and other medications to lower possible high blood pressure (beta blockers, ACE inhibitors, ARBs, calcium channel blockers and diuretics). The other treatment for stroke is surgery to remove blood clots, to repair blood vessels, and surgery to remove plaque from the carotid artery. artery. A non-surgical procedure after a stroke is carotid angioplasty and stenting, which is a balloon-shaped device that unblocks the artery and a metal piece is placed to keep it open. Another procedure is bonding aneurysm, a treatment that fills weak ruptures. blood vessels with tiny, flexible platinum spirals. The economic impact of this disease on Canada is enormous. The annual cost is around 2.7 billion for nurses, doctors, drugs, hospitals and research..
