Cerebrovascular disease is one of the major diseases that endanger the health and life of middle-aged and elderly people. Stroke is the main clinical type of cerebrovascular disease, also known as stroke, including ischemic stroke and hemorrhagic stroke, which is a disease characterized by sudden fainting and unconsciousness, with distorted mouth, unfavorable speech, hemiplegia, or only distorted mouth and hemiplegia as the main clinical symptoms. It is the second leading cause of human death and, together with ischemic heart disease and malignant neoplasm, constitutes the third leading cause of death in most countries. Strokes can be divided into two categories: ischemic strokes and hemorrhagic strokes. Ischemic stroke, also known as cerebral infarction, is a clinical syndrome caused by ischemic and hypoxic necrosis of local brain tissue due to impaired blood supply to the brain from various causes. It is the most common type of stroke, accounting for about 70%-80% of cases. Hemorrhagic stroke refers to cerebral hemorrhage, which is mainly caused by the rupture and bleeding of small arteries in the brain due to chronic lesions caused by long-term hypertension. The incidence of cerebral hemorrhage is lower than that of cerebral infarction, but the mortality rate is high, with an acute mortality rate of 30%-40%. So how do you know you’ve had a stroke? Stroke is not a disease that grows on you for no reason, it is something that we develop over time. These risk factors include: age 50 years or older, higher incidence of diabetes in men than women, heart disease, disorders of lipid metabolism, transient ischemic attack, smoking and alcohol abuse, obesity, hypertension, etc. Stroke occurrence is also associated with psychological disorders, mental stress, mood swings, etc. For example, irritable people supply more blood to the brain when they are angry and are prone to stroke at this time. In addition, studies have found that strokes are likely to occur in winter each year, especially when climate change is intense. Therefore, for people at risk of stroke, it is important to control blood pressure, blood sugar and blood lipids, keep emotionally stable, keep warm, do the necessary physical exercise, control the amount of meals, maintain body weight, and stop smoking and alcohol abuse. Stroke aura symptoms: People at high risk of stroke with the above risk factors should be alerted to the occurrence of stroke aura, such as irritability, dry mouth, dizziness, fatigue, foul breath, unresponsiveness, blurred vision, drowsiness and sleepiness, head swelling, and sticky phlegm; frequent headache, sleepiness after eating, dry eyes, ringing in the ears, and dry and constipated stool, which increase the risk of stroke. Patients with the above uncomfortable symptoms are advised to go to a regular hospital medical institution in a timely manner.
