No matter the morbidity rate or impotence, cerebrovascular disorder is on the top of all nervous system diseases found in adults. A stroke is brain abnormalities which are caused by the pathological process of the blood vessels. This disease is normally presented in acute attack in the middle-aged people and/or elderly, which may cause consciousness disorder and limb paralysis. Stroke is a major disease that can cause death and physical disability; the main cause of death for patients is when they present high blood pressure results.
According to a different property, the classification of strokes is a ischemic cerebral vascular disease and a hemorrhagic cerebrovascular disease. Ischemic cerebral vascular disease is more common, cerebral infarction occupies 59.2%-85%, cerebral hemorrhage is less than 20% in different countries, except Japan.
Ischemic cerebral vascular disease:
(2) Cerebral thrombosis is a blood clot formed from the cerebral blood vessel local lesions, which is caused by atherosclerosis, arthritis, trauma, blood disease and other physical factors.
(3) Cerebral embolism may be caused by an embolus, from many kinds of diseases, or an obstruction of the blood vessels in the brain. Although, heart disease is the most common cause, next in importance are embolus from fractures, or post-traumatic fat in the blood, eggs or bacterial infection, pneumothorax air into the blood, and/or phlebophlogosis.
Hemorrhagic cerebrovascular disease
Pathology of Stroke
The pathology of cerebral ischemia and ischemic infarction include two pathological and physiological processes:
Neurovascular Syndrome: Different arterial occlusion and patients physical quality is caused by different symptoms, but there are still some typical symptoms: such as three partial syndromes and lacunar syndrome in pars geniculate artery stroke, etc.
Wu Stem Cells Medical Center found that necrotic nerve cells cannot regenerate after they die, which is caused by extensive damage of ischemia and hypoxia, but reserve cells and the cells around the lesion can be activated and are useable, which is brought about by regulation of the neural stem cell transplantation.
Wu Stem Cells Medical Center researchers found that the cerebrovascular disease is caused by vascular pathological factors resulting in nerve cell necrosis and number decrease, then the cells function is reduced or even lost, supplement neural stem cells can be activated in the expression function of the cells in the tissue, those viable neural stem cells can lead the reserve cells in the tissue to react, migrate and differentiate. They can also start the vascular reconstruction and repair a part of the remnant lesions, so the number of neural cells are increased, promoting function and recovering the function which was lot.
