A sudden stroke is a cerebral circulation disorder that alters the function of a particular region of the brain. These are disorders that usually affect older people, although they may also occur in young people and often are the end result of the confluence of a series of personal, environmental and social risk factors. A stroke can be produced both by a significant decrease in blood flow in the brain or a hemorrhage due to the rupture of a cerebral vessel. If you think you are having a stroke, see Doctors in Maui immediately.
In the first case, experts speak of an ischemic stroke. These are the most frequent strokes (up to 85%) and the final result is a stroke, an irreversible situation that leads to the death of brain cells affected by lack of oxygen and nutrients carried by the blood. In the second case, experts refer to a hemorrhagic stroke, Even though they are less common, mortality is considerably higher. In return, hemorrhagic stroke survivors often have medium term, less serious consequences.
In relation to these considerations, Doctors in Maui distinguish several major types:
Thrombosis is an ischemic stroke caused by a blood clot (thrombus), formed in the wall of a major artery, blocking blood flow to the brain.
* Embolic stroke is like an ischemic stroke, meaning thrombotic like, and is caused by a blood clot.
* Hemodynamic stroke is most uncommon. The blood supply deficit is due to a decrease in blood pressure.
* Intracerebral hemorrhage is the most common hemorrhagic stroke. A deep cerebral artery tears and lets out blood content, which spreads between the surrounding brain tissue and causes swelling.
* Subarachnoid hemorrhage is a localized bleeding between the brain surface and the inside of the skull. Its most common cause is the rupture of an arterial aneurysm (an abnormally thin portion of the wall of an artery, which takes the form of balloon or bag).
Although its form of presentation is unexpected, a stroke might seem like an unpredictable catastrophe, but in most cases it is not. A stroke is the end result of the accumulation of a number of lifestyle habits and unhealthy personal circumstances (risk factors).
