Cerebrovascular insufficiency is one of the most common types of pathologies, which results from chronic blood flow abnormalities in the cerebrum, as well as abnormalities in transport and utilization of nutrients in the cerebral cells, which in turn is one of the main reasons for atherosclerotic changes in the tissues of elderly patients. Clinically the pathology is manifested by abnormalities of the cerebral function and decline of overall well-being.
The research has shown that cerebral insufficiency can be seen in nearly 50% of the human population. Epidemiological research also states that the age of the disorder has significantly decreased, and nowadays even young adults suffer from it.
The disease is extremely prevalent in elderly patients, especially in developing and developed countries, due to changes in flexibility of the arteries or hardening of the vessel walls in atherosclerosis. In a large number of cases the disorder affects the carotid artery. These arteries supply the brain with blood and are located parallel on the sides of the neck. The disorder develops occasionally at the carotid bifurcation or the place where the artery is split into internal or brain supplying branches and external or face and scalp supplying branches. The symptoms of the disorder appear when the blockage of the artery reaches 90%, thus causing brain hypoxia and in extreme cases even stroke. Transient symptoms of the disorder include:
