Cerebrovascular disease is a blood vessel disease in the brain, especially the brain arteries. Arteries in the brain deliver blood that supplies essential nutrients and oxygen to brain tissue. Cerebrovascular disease arises from time to time because the blood vessels in the brain are susceptible to damage caused by hypertension or intermittent high blood pressure, high cholesterol, diabetes, lower blood vessel disease, or smoking.

Injuries to the inner lining of blood vessels cause blood vessels to be narrow, stiff, and sometimes irregular in shape. Often times unhealthy blood vessels are described as having atherosclerosis, which is hardening in the inner layer, usually associated with increased cholesterol.

How do cerebrovascular diseases cause strokes?

Blood vessels in the brain that have developed cerebrovascular disease are prone to blood clots. Blood clots begin to form in the arteries when the arteries are narrowed or deformed. Blood clots that grow in blood vessels are called thrombus. Thrombus that flows through a blood vessel to another location of the body is called an embolus. Thrombus or embolus can be trapped in narrow blood vessels in the brain, especially those that have been damaged by cerebrovascular disease, causing a disruption of the blood supply called ischemia. Abnormalities due to cerebrovascular disease also cause blood vessels to become more easily torn, increasing the risk of bleeding.

In strokes caused by damage to bleeding tissue, damage to brain tissue due to bleeding is the same as damage to brain tissue due to ischemia, both of which occur simultaneously.

When cerebrovascular disease develops, it causes heart disease and vascular disease also appears in the body. The cause of cerebrovascular disease is similar to the cause of other vascular diseases. Some people are more susceptible to vascular disease.

There are several genetic conditions that cause cerebrovascular disease to have more impact on blood vessels in other parts of the body.

What are the consequences of cerebrovascular disease?

The presence of cerebrovascular disease can cause mild strokes over time. Because the brain has the ability to compensate for a number of injuries, many people suffer from minor strokes and do not experience symptoms because the brain tissue area is not affected. Often, people who have mild strokes, caused by cerebrovascular disease are surprised when they are told that an MRI or CT scan of the brain shows evidence of a previous stroke. In this situation, reports on the results of CT scans or MRI will mention 'small vessel disease,' 'lacunar strokes' or 'white matter disease.' Over time, if several minor strokes occur, a critical threshold can be reached. At this point, symptoms can suddenly become clear if the brain's compensation ability is overwhelmed.

Cerebrovascular disease can worsen the symptoms of dementia or senility. Some people with sustained cerebrovascular disease do not show stereotypical symptoms such as tiredness, difficulty speaking, or loss of vision, but show symptoms of senility. This is caused by the difficulty of the brain integrating thoughts and memories as a result of various minor strokes over time.

What triggers cerebrovascular disease?

Long-term cerebrovascular disease can cause sudden strokes. Thrombus causes blood clots to flow from the heart or carotid artery to the brain which is a common trigger. The possible trigger is sudden extreme hypertension. Other triggers that can cause cerebrovascular disease and the occurrence of sudden strokes, namely blood vessel spasm or blood vessel spasm, occur due to drugs or sudden changes in blood pressure.

How do doctors diagnose cerebrovascular disease?

There is usually no screening test to determine the presence of cerebrovascular disease, although sometimes the signs can be detected in brain studies. The absence of cerebrovascular disease shown by CT or MRI is not necessarily accurate. Monitor risk factors that cause the development of cerebrovascular disease to worsen. Some cerebrovascular diseases can at least be reduced by lowering cholesterol, controlling blood pressure and diabetes, and quitting smoking.
