The human brain accounts for about 2% of body weight, but oxygen and blood consumption account for about 20% of total body mass, with average blood circulation around 55ml / 100g of brain within 1 minute. The brain is provided by two pairs of arteries: the vertebral artery and the internal carotid artery. After two pairs of arteries together into a polygon at the base of the brain divides the prefrontal, middle, and posterior cerebral arteries to provide blood to the brain. Thus, the concept of ischemic diseases is diverse. If a person has a stroke, he or she will have two types: cerebral hemorrhage and localized cerebral infarction (also known as cerebral infarction or cerebral infarction).
If the blood supply to the brain from 30 to 50ml is called brain circulatory dysfunction, not cause focal neurological damage. Blood supply decreased due to fibrosis of the blood vessels or some vertebrae of the vertebrae causing arterial spinal cord compression reduces the blood flow to the brain. If compression in the internal carotid artery causes a decrease in blood supply to the frontal lobe, compression in the arterial vertebral artery causes a reduction in blood supply to the posterior and posterior cerebellum. It will cause clinical symptoms such as headache, dizziness, memory loss, sleep disorders ...
