A stroke is a serious medical situation that normally befalls when a clot within the blood has clogged the flow of blood to the brain. When the brain fails to get the blood and the suitable quantity of oxygen, the brain cells literally die. Brain cell function necessitates a continuous delivery of oxygen and glucose from the bloodstream. The deficiency of oxygen and glucose rolling to the brain leads to the death of brain cells and brain impairment, often occasioning in impairment in speech, movement and memory. The two main kinds of stroke include ischemic stroke and hemorrhagic stroke.
Causes
Ischemic strokes are eventually caused by a thrombus or embolus that blocks blood flow to the brain. Blood clots (thrombus clots) typically happen in zones of the arteries that have been impaired by atherosclerosis from an accumulation of plaques. Embolus type blood clots are often instigated by atrial fibrillation i.e. an asymmetrical pattern of heart beat that result in blood clot formation and poor blood flow. Hemorrhage strokes can be caused by …show more content…
Therapies to avert a first or recurring stroke are based on treating a person's underlying risk factors for stroke. The chief goal in treating ischemic stroke is to reestablish blood flow to the brain. This will be endeavored using blood clot-busting drugs such as aspirin, heparin or tissue plasminogen activators that must be administered within three hours of the stroke. Furthermore, surgical techniques might be executed that can open up or broaden the arteries. These embrace carotid endarterectomy (elimination of plaque and widening of the carotid artery) and angioplasty. Hemorrhagic stroke is treated differently than ischmic stroke. Surgical approaches used to treat this stroke variant include aneurysm clipping, aneurysm embolization and arteriovenous malformation (AVM)
