Two types of stroke(CVA) cerebrovascular accident exist, the first type is a hemorrhagic stroke. This is when a blood vessel in the brain ruptures and blood is leaked into the cerebral tissue. The etiology is due either to a weakened vessel wall and or severe hypertension.
The second type of CVA is called an ischemic stroke. In an ischemic stroke, the lumen of a blood vessel is narrowed by either a thrombus or a cholesterol laden plague. A sufficient amount of blood can not traverse the thrombus, brain tissue is deprived of blood and the patient experiences symptoms of a CVA.
Theoretically, stroke can be prevented by several measures. First, proper regulation of blood pressure is key. A vast majority of CVA victims have uncontrolled hypertension.
Second, steps should be taken to prevent hyperlipidemia. Again, a vast number of CVA patients have hyperlipidemia.
If the only etiology of this vascular event is the fact that the patient had a weakened blood vessel wall, then there is no way to prevent this from occuring because the disorder is probably a congenital anomoly.
Some CVA patients will have facial paralysis after the stoke. Physical manifestations after CVA depend on the area of the brain that was affected.
The National Stroke Association recommends the following for stroke prevention:
- Know your blood pressure
- Find out if you have atrial fibrillation
- Do not smoke
- If you drink alcohol, drink it in moderation
- Find out if you have high cholesterol and if you do you need to get it down
- If you have diabetes, keep it under control
- Monitor sodium and fat intake
- Be aware of any circulation problems you may have
- Know the symptoms of a stroke
Facial paralysis is an effect of a stroke. If the blockage or hemorrhage happened on the left side of the brain it means the stroke occurred on the right side of the brain. When a stroke hits the primary motor cortex then facial paralysis occurs.
