Cerebrovascular insufficiency occurs when there is an obstruction in one or more arteries that supply blood to the brain. What makes cerebrovascular insufficiency so unique is that these obstructions can occur for any number of reasons. The obstruction leads to stroke or transient ischemic attacks. In children and some adults one of the most common causes for cerebrovascular insufficiency is a condition called Moya-Moya disease.
Stroke Risk Factors
About 25 percent of the people who recover from their first stroke will experience another one within five years. To prevent this from happening, patients may be prescribed anticoagulants, which thin the blood and help prevent clots from forming.
Antiplatelet drugs also may prevent clots from forming, by slowing down the blood cells that cause the clots to form. This regimen may involve taking an aspirin a day, or using prescription medications such as Coumadin and Plavix.
Surgery to open clogged arteries is another option that doctors may consider.
Patients also are encouraged to modify any behaviors that may contribute to a greater risk of experiencing a stroke.
Men are at a higher risk for stroke than women, until their later years when the odds become more even.
Race is also a factor. Blacks are twice as likely to experience a stroke and are twice as likely to die from it, than their white counterparts. Some think this gap may be the result of differences in economic levels.
Among whites and blacks, socioeconomic factors appear to matter. Impoverished areas in Arkansas, South Carolina, Georgia and Tennessee report the highest stroke fatality rates in the nation.
High blood pressure is the main cause of strokes, being responsible for approximately two-thirds of all cases. It is also responsible for about half of all heart attacks. That’s why it’s so important to reduce or control your blood pressure through weight loss, a reduced-sodium intake, a healthy diet (e.g DASH Diet), increased physical activity and if needed, medication.

Symptoms of obesity, high blood pressure and high cholesterol, can put you at risk for stroke. Some strokes, known as “silent strokes” can occur without symptoms -but each time, blood is cut off to the brain, resulting in damaged, dementia-prone brain tissue. High blood pressure and cholesterol can also increase the likelihood that you’ll develop Alzheimer’s disease.
