What is cerebral vascular disease

Cerebral vascular disease occurs in the brain vessels, intracranial blood circulation disorder caused brain damage in a group of diseases, sub-acute and chronic two. Usually what we call a cerebral vascular disease is mainly acute cerebrovascular disease. Due to sudden onset, suggesting fierce and changes fast, there "cerebral vascular accident", "stroke" and "stroke" said. As the motherland medical description "stroke is a disease, such as Shi Shi among people, and to suddenly have" suddenly seem to be a stone hit head-bashing cases the same. "Stroke" for a sudden stroke was intended. These terms are referring to acute cerebral vascular disease. Cerebrovascular disease generally fall into two categories, one category of ischemic cerebrovascular disease, cerebral artery by the brain diseases such as atherosclerosis, resulting in regional cerebral artery lumen narrowing or complete obstruction, or blood clotting, causing the brain blood supply interruption, there pathological brain tissue necrosis softening. Normally the cerebral thrombosis and cerebral embolism, are ischemic cerebrovascular disease, cerebrovascular disease such cerebrovascular disease accounted for a total of 60%. The other is hemorrhagic cerebrovascular disease, is due to long-term high blood pressure, hardening of the brain arteries formed a miliary size Ectasia (known as micro-aneurysms), when blood pressure for some reason suddenly rises, can cause micro-aneurysms rupture, so cerebral hemorrhage. Also known as the cerebral brain hemorrhage and subarachnoid hemorrhage are of this type. In recent years, because of the effective prevention and treatment of hypertension, hemorrhagic cerebrovascular disease has decreased, the total number of cerebrovascular disease accounted for about 40%, but in case of cerebral hemorrhage, often more serious illness and mortality are high. Some people regard the various causes of hemiplegia, has called hemiplegic limb stroke, it can only say that it is a commonly known as or collectively, because in addition to the above two types of brain disease, hemiplegia minority can systemic diseases such as metabolic diseases, blood diseases and brain tumors (including distant organ metastasis to the brain tumor thrombus) caused . This paper describes the main cerebrovascular disease itself caused the brain disease.
