Vascular diseases often affect the brain by depriving it of oxygen-rich blood. Vascular problems are quite common and may lead to serious complications if not treated in a timely manner, notes MedlinePlus.
The cardiovascular system is made up of capillaries, veins and arteries responsible for carrying blood to and from the heart. A cardiovascular disease is any condition that affects the circulation of blood in the human system, notes SecondsCount.
In some cases, a cardiovascular disease may partially block the veins, while in other cases the disease may completely block the vein. When this happens, the brain does not get sufficient amounts of oxygenated blood.
When some parts of the brain do not get enough blood or go without blood, the cells in that particular area begin to die. This process takes a few seconds. A stroke can easily occur in such a situation because the brain cells responsible for the function of one part of the body begin to die.
Blockages to the veins or arteries usually occur when their is a buildup of plaque in one particular area. Plaque is made up of fats and cholesterol. Some cardiovascular conditions can be remedied by drugs that help in blood thinning. However, serious cases may require surgery.
