Stroke is a serious threat to the health and life of middle-aged and elderly people. To prevent stroke, we must first have a correct understanding of it in order to take the right measures against it. However, there are many people in real life who have a vague understanding or even misunderstanding of stroke, and it is necessary to clarify them. These misconceptions are summarized in the following eight points: 1. Stroke is a disease. In fact, stroke is not a disease, it is a generic or common name for acute cerebrovascular disease. In fact, stroke is a class of diseases, including six diseases such as cerebral hemorrhage, subarachnoid hemorrhage, cerebral infarction, cerebral thrombosis, lacunar cerebral infarction and mini-stroke (transient ischemic attack). The first two of them belong to hemorrhagic stroke, and the last four belong to ischemic stroke. 2. Only middle-aged and elderly people get strokes. Although more than 90% of strokes occur in middle-aged and older people over the age of 40, young people can also get strokes, especially subarachnoid hemorrhage, which is not uncommon in young people. Children occasionally get strokes as well. 3, people with normal or low blood pressure must not have a stroke. It is true that more people with high blood pressure suffer strokes, but patients with cerebral atherosclerosis who have normal or low blood pressure can also have strokes because the lumen of the cerebral arteries becomes highly narrowed and other factors exist. Especially low blood pressure can lead to cerebral blood flow becomes slow, more likely to occur ischemic stroke. 4, thin people rarely get a stroke. Thin people can also get a stroke, but is slightly less than fat people. 5, a stroke will not die, but will be disabled. This was the case in the past, but in recent years due to the continuous progress of medical technology, the cure rate of stroke has increased significantly, the 5-year survival rate after a stroke has reached about 62%, the average life expectancy has reached 66 years, and the sequelae have been greatly reduced. 6. Stroke can only be treated conservatively with internal medicine. This was true in the past, but in recent years, surgical treatment has been carried out at home and abroad, and the results are better. Ischemic stroke to carry out extracranial artery bypass surgery, large omental intracranial graft, vertebral artery decompression, etc.; hemorrhagic stroke surgical indications is a medium amount of bleeding by conservative medical treatment is not effective, there are two main types of surgery: open cranial removal of hematoma and stereotactic surgery to remove the hematoma. 7. Stroke rarely recurs after cure. Stroke is very easy to recur, the recurrence rate is as high as 25%, and there are multiple recurrences. This is because the so-called stroke cure is only the disappearance of clinical symptoms, its pathological basis – atherosclerosis, hypertension and blood rheological changes, are not cured, so should be taken seriously recurrence. 8, parents suffering from stroke, the children must get. Stroke is not a genetic disease, only part of the stroke has a genetic predisposition. Therefore, the children of stroke patients need not worry. However, it should be noted that the risk of stroke for these people may be greater than the general population. For this reason, they should strengthen their self-care and carefully and actively prevent and treat hypertension, hyperlipidemia and atherosclerosis.
