Arteriosclerosis of the clinical manifestations of cerebral infarction

Arteriosclerosis stroke, also known as atherosclerosis thrombosis stroke, brain atherosclerosis and thrombosis, cerebral vascular lumen stenosis or occlusion, leading to acute cerebral insufficiency, caused partial brain ischemic necrosis. Patients may appear hemiplegia, aphasia focal brain damage and other symptoms, an ischemic stroke. to the elderly. High-fat diet, diabetes, smoking, such as patients with a higher incidence rate. Caused cerebral vascular obstruction There are two main reasons: First, cerebral thrombosis, which is itself due to cerebral vascular lesions, often cerebral artery atherosclerosis so that the lumen endometrial rough, narrow the lumen, under certain conditions, such as Lower blood pressure, blood flow slow. Increased blood viscosity, such as platelet clotting factor in blood vessels can make the block, a cerebral thrombosis. The other is the cerebral embolism, it is other parts of the body of thrombosis loss, with the blood flow to the brain blood vessel blockage, caused cerebral embolism. Such emboli can be the vegetation from rheumatic heart disease, may also be fracture of the fat emboli, or blood into the air from air embolism, or loss of tumor cells formed tumors embolism, and so on. Cerebral thrombosis caused by cerebral infarction, the slow onset, often in quiet sleep or rest when, which may lower blood pressure and rest, of the slow flow. From the onset to peak condition to development, often take several minutes or even several days. And cerebral embolism caused by cerebral infarction, more than the onset Jizhou, often in seconds or minutes of the peak.
