Stroke is a medical condition that requires emergency care to prevent irreversible brain damage or worse from occurring. Moreover, stroke is most treatable when caught early on, so be sure that you seek medical treatment at the first signs of stroke. Our medical doctors specialize in emergency medical care at Houston Medical ER and can provide you with life-saving care if you or someone you care for experiences a stroke.
A stroke is reduced, interrupted, or excessive blood flow to one part of the brain, which either prevents that part of the brain from getting the oxygen and nutrients it needs to function correctly and survive or puts too much pressure on the brain cells. Consequently, brain cells begin to die within minutes when a stroke occurs, which is why a stroke is considered a life-threatening medical emergency. A stroke can lead to irreversible brain damage, death, and various other complications.
There are three main types of stroke: ischemic stroke, hemorrhagic stroke, and transient ischemic attack (TIA).
Ischemic strokes are the most common type of stroke, accounting for approximately 87 percent of all strokes, and involve reduced or blocked blood flow in the artery that supplies the oxygen-rich blood to the area of the brain experiencing the stroke.
In contrast, hemorrhagic strokes are much less common and occur when arteries in the brain rupture, causing excessive blood flow to the surrounding brain tissues.
A TIA stroke, also known as a mini-stroke, involves a temporary interruption of blood flow to the brain, usually occurring for approximately five minutes. As such, TIA strokes are typically regarded as warning signs that an ischemic stroke could be imminent and therefore require immediate medical attention.
Since ischemic and hemorrhagic strokes occur differently, they also have different causes. With that in mind, the causes of an ischemic stroke often include any of the following:
Concerning hemorrhagic strokes, they can occur due to any of the following causes:
In some cases, a hemorrhagic stroke can be caused by an initial ischemic stroke.
Various conditions, lifestyles, and habits qualify as risk factors for stroke, including the following:
Most of the signs and symptoms of a stroke occur suddenly. With that in mind, the signs and symptoms of a stroke are as follows:
