DISEASES >> STROKE
A
stroke occurs when an artery to the brain becomes blocked or ruptures, resulting in death of an area of brain tissue. There are two types of
strokes: ischemic (blockage of an artery) and hemorrhagic (rupture of an artery). About 80% of
strokes are ischemic—usually due to a blocked artery, often blocked by a blood clot.
Risk factors
- Atherosclerosis (narrowing or blockage of arteries by patchy deposits of fatty material in the walls of arteries)
- High cholesterol levels
- High blood pressure
- Diabetes
- Smoking
Prevention
Preventing
stroke is preferable to treating them. You can prevent
strokes by managing the major risk factors. Exercising controls high cholesterol levels, high blood pressure and diabetes. Checking up with your doctor frequently also helps detect the risk factors and manage them. On the other hand, those with the symptoms of
stroke should heed the advice of doctor.
