A stroke is the interruption or severe reduction of blood flow to certain parts of the brain. Brain cells require a constant supply of oxygen and without that supply brain cells begin to die. Every minute a stroke goes untreated, 1.9 million brain cells die.
Stroke is currently the fifth leading cause of death in the United States and is the leading cause of disability in adults. Stroke has been identified as one of the leading causes for admission into long-term care facilities in North Dakota.
There are different types of strokes that occur:
An ischemic stroke is caused by a blood clot. The blood clot blocks blood flow to the brain causing brain cells to die. About 87% of strokes are ischemic.
A hemorrhagic stroke is caused when a tear in an arterial wall or a blood vessel bursts. When this occurs the brain bleeds. Blood accumulates in the brain and compresses the surrounding brain tissue. Hemorrhagic strokes are less common, but are more serious and often are deadly.
Transient Ischemic Attack
A Transient Ischemic Attack, or TIA for short, is often referred to as a mini stroke or a warning stroke. This is because a TIA often comes before a major stroke occurs.
With a TIA, the blood flow to part of the brain is blocked or reduced for a short period of time which causes symptoms similar to a stroke. These symptoms only last for a short amount of time. Despite the short duration of symptoms, TIAs should be taken seriously and medical care is needed immediately. A person who has a TIA is almost 10 times more likely to have a stroke.
If you or someone you know shows any sign of stroke call 9-1-1 immediately. 9-1-1 is the fastest access to stroke care.
Stroke is one of the leading causes of admission into long-term care in North Dakota.
Nationwide, stroke is now considered more disabling than it is fatal. Access to immediate care offers stroke victims the best chance at recovery.
