Cerebrovascular disease is mostly seen in people with hypertension and cerebral arteriosclerosis, and is especially common when overworked and experiencing dramatic mood swings. Therefore, effective treatment and control of hypertension and avoidance of excessive mental tension and fatigue are the main links in the prevention of cerebrovascular disease. But the change of climate is also a factor that can not be ignored to induce cerebrovascular disease. According to the survey, about more than half of the patients, occur in the late autumn and early winter when the climate changes suddenly. This is because: 1, low temperature can make the elasticity of body surface blood vessels decrease, peripheral resistance increases, blood pressure rises, which in turn leads to cerebrovascular rupture and bleeding. 2, cold stimulation can also make sympathetic excitation, adrenocorticotropic hormone secretion increases, which causes small arteries to contract spasmodically, increasing the peripheral resistance, blood pressure increases. 3, cold can also make the blood fibrinogen content increased, blood concentration increased, prompting the formation of emboli in the blood and the onset of disease. The key to preventing cerebrovascular disease is to actively control risk factors: a. To scientifically manage blood pressure: hypertension is the first risk factor for cerebrovascular disease, temperature changes are likely to cause fluctuations in blood pressure, hypertensive patients should standardize their medication and strictly control their blood pressure. However, controlling blood pressure does not mean lowering blood pressure to a very low level, and low blood pressure is also a risk factor for ischemic cerebrovascular disease. Therefore, you should learn to self-monitor your blood pressure and consult your doctor regularly. Second, to actively treat the primary disease: if there is a previous heart disease (such as valve disease, non-rheumatic atrial fibrillation, coronary artery disease, myocardial infarction, cardiac insufficiency, etc.) to actively carry out treatment. Third, diabetes and hyperlipidemia should be closely monitored: excessive blood glucose and blood lipids have a great impact on blood vessels, and strict blood glucose control can effectively reduce the incidence of cerebrovascular disease. Fourth, people with a history of TIA and stroke should pay attention to self-monitoring: TIA is also commonly known as mini-stroke, which refers to the appearance of dizziness, headache or inflexible activities and speech and other symptoms, because these symptoms last for a short time, many people think there is nothing wrong, but this situation is precisely the most dangerous kind of cerebrovascular disease, nearly 50% of people will have a cerebral infarction within 5 years. Five to change bad habits: smoking, drinking, staying up late, eating too salty and greasy food, reduced physical activity, high mental tension and abuse of oral contraceptive drugs, etc., are risk factors for disease, which can be self-control and avoid. Sixth, regular health checkups should be done: monitor blood pressure, blood lipids, blood sugar, and actively treat medical system diseases to achieve early detection and early treatment. Seven, patients with clear symptoms of cerebrovascular disease are recommended to perform cerebrovascular examinations such as cerebral angiography, TCD, head and neck CTA, etc., to clarify the lesioned vessels at an early stage for early treatment.
