Stroke occurs when there comes an interruption in brain and supply of blood somehow does not reach or the supply is low. When this situation occurs, the supply of adequate oxygen that a brain needs reduces and thus it causes brain cells to die. Stroke is considered as the fourth leading disease that is causing death in USA. It is researched that it is so dangerous one person dies daily after every four minutes through stroke.
It has been calculated that nearly about 800,000 gets affected by stroke and after every 4 seconds some where someone is suffering through the condition of stroke.
Types of stroke:
There are three types of strokes; ischemic, Hemorrhagic and Transient Ischemic attack (TIA).
Ischemic strokes are the common strokes and around 85% of strokes are of this type. These are caused when the arteries that are connected to the brain somehow gets blocked or narrowed. These blockages are often caused when the blood clots occur in the brain. Clots can be caused due to fatty arteries that deposit in the arteries. Cerebellar stroke is one of them in which blood clot occurs in brain.
This type of attack is caused by the arteries in the brain because of the leakage of the blood or results in burning. The hemorrhaged blood puts pressure on the brain cells thus resulting in damage. Blood vessels can spill the blood to the middle of the brain or near the surface of the brain, this results in sending blood into the space that is between brain and skull. Brain stem stroke is one of the kind in which bleeding occurs in the brain.
Transient ischemic attack:
TIAs are different from the two strokes mentioned earlier because the flow of blood to the brain is disrupted for a short period. These are somehow common to the ischemic stroke in one manner as it is also caused by blood clot or other debris.
TIAs should be treated immediately even if the blockage in the artery occurs temporarily. These serve as warning signs from the future strokes and it is also an indicator that there is partial blockage that needs to be checked.
What causes Stroke?
There are different causes of stroke. Stroke affect those people who are either overweight and age varies in different region but the approximate age is 55 or older, if that family is having a personal or family history regarding stroke, those who do not exercise that much or are not that much concerned about their health, if they drink heavily or use dangerous and heavy drugs. A stroke is a typical medical emergency and it needs to be treated as soon as possible as it may result in serious side effects.
Signs of stroke and symptoms of stroke:
There are different signs of stroke that may appear suddenly without any warning.
Confusion state; trouble while speaking and understanding something. Headache; feeling of vomit; numbness may appear on the face, arm or leg particularly on one side of the body; trouble in vision; trouble while walking including dizziness and lack of coordination. These are some of the symptoms of stroke.
Treatments of stroke:
As all three types of stroke are different therefore the treatment of strokes are also different. Ischemic strokes are caused when a narrowing or blocking of arteries occur. These can be treated if clot busting drugs are used. Hemorrhagic strokes are caused when the blood flows in and around the brain or either due to leakage of arteries. This can be treated by surgery, when the ruptured vessel or the artery gets repaired.
