Cerebral infarction 1, cerebral infarction (cerebral infarction, cerebral infarction, ischemic stroke): cerebral infarction is the destruction of brain tissue in the corresponding area after the blockage of cerebral arteries, which may be accompanied by the issuance of blood. The pathogenesis is thrombosis or embolism, and the nature of the symptoms varies depending on the vessels involved. Cerebral infarction accounts for 70% to 80% of all strokes. 2. Etiology: Cerebral infarction is caused by a sudden reduction or cessation of blood flow in the local blood supply artery of the brain tissue, resulting in ischemia and hypoxia of the brain tissue in the blood supply area, leading to necrosis and softening of the brain tissue, with clinical symptoms and signs in the corresponding area, such as hemiplegia, aphasia and other neurological deficits. 3.Main factors: hypertension, coronary heart disease, diabetes, overweight, hyperlipidemia, fatty food, and many patients have family history. It is mostly seen in middle-aged and elderly people aged 45 to 70. 4. Clinical symptoms: The clinical symptoms of cerebral infarction are complicated, which are related to the location of brain damage, the size of cerebral ischemic vessels, the severity of ischemia, the presence or absence of other diseases before the onset, and the presence or absence of other important organ diseases, etc. The milder cases can be completely asymptomatic, i.e. asymptomatic cerebral infarction; they can also show recurrent episodes of limb paralysis or vertigo, i.e. transient ischemic attack; the heavier cases can not only have limb paralysis, and even acute coma and death. If the lesion affects the cerebral cortex, the acute phase of cerebrovascular disease can be manifested as the appearance of seizures, with the highest incidence within one day after the disease, while cerebrovascular disease with epilepsy as the first is rare. 5. Treatment: Attention should be paid to the treatment of hypertension in this disease, especially those who have had lacunar infarction in their medical history need to prevent recurrence, and care should be taken that blood pressure is not too fast or too low. (1) Acute phase The principle is to improve the blood circulation in the cerebral ischemic area and promote the recovery of neurological function as soon as possible. (2) Recovery period Continue to strengthen functional exercises of paralyzed limbs and functional training of speech. In addition to drugs, physical therapy, body therapy and acupuncture, functional food, etc. can be used in conjunction. Cerebral hemorrhage 1. Cerebral hemorrhage (cerebral hemorrhage): It is a kind of “stroke” and a common serious brain complication in middle-aged and elderly patients with hypertension. Cerebral hemorrhage refers to non-traumatic bleeding caused by rupture of blood vessels in the brain parenchyma, the most common causes are hypertension, cerebral atherosclerosis, intracranial vascular malformation, etc., often triggered by force, emotional excitement and other factors, so most of the sudden onset in the activity. 2.Clinical manifestations: The onset of cerebral hemorrhage is very rapid, mainly manifesting as impairment of consciousness, limb hemiparesis, aphasia and other neurological damage. It is one of the fatal diseases of middle-aged and elderly people because of its rapid onset, dangerous condition and very high mortality rate. 3, hypertension: the most common cause of cerebral hemorrhage is hypertension, which is one of the most serious and highest level complications of hypertension and can cause death in a short period of time with extremely serious symptoms, even affecting the basic physiological activities of patients such as breathing and heartbeat in a short period of time. Taking into account all other causative factors, it is important to emphasize the point that hypertension must be effectively controlled in order to effectively avoid hypertensive cerebral hemorrhage. On the basis of the long-term effects of hypertension, any factor that can induce a short-term increase in blood pressure can lead to the occurrence of hypertensive cerebral hemorrhage. 4, treatment: the treatment of hypertensive cerebral hemorrhage can be divided into conservative medical treatment, surgical treatment.
