Dystrophic metaplasia of brain cells is usually referred to as primary hypertension with mental disorders, which is the most common type of mental disorder associated with vascular disease, and refers to the mental disorders that accompany the development of primary hypertension. Psychiatric disorders associated with primary hypertension mainly manifest as neurotic-like syndrome, but also depressive syndrome, hallucinations, delusional states, etc. When hypertensive crisis occurs with a sharp increase in blood pressure, it often manifests as a disorder of consciousness. What is the primary prevention of dystrophic metaplasia of brain cells? The key to mental disorders associated with primary hypertension is to prevent the onset and development of primary hypertension. Primary prevention of hypertension refers to taking effective preventive measures to control or reduce the risk factors for the development of hypertension in people who have risk factors that cause hypertension, but have not yet developed hypertension, in order to reduce the incidence. Secondary prevention refers to taking effective treatment measures for people who already have hypertension to prevent further development of hypertension and the occurrence or recurrence of complications. Tertiary prevention refers to the resuscitation of severe hypertension to prevent its complications and the death of the patient. Included in tertiary prevention is rehabilitation. What are the primary prevention measures included? I. Reasonable adjustment of diet: 1. Restrict excessive sodium intake. 2.Increase the intake of potassium. 3.High calcium intake. Low calcium intake can raise blood pressure. A 100 mg increase in daily calcium intake can lower systolic blood pressure by 0.33 kPa (2.5 mmHg) and diastolic blood pressure by 0.17 kPa (1.3 mmHg). The recommended daily calcium intake is 800mg per person, which can be increased by drinking milk, increasing beans and fresh vegetables and fungus, shiitake mushrooms, shrimp skin and nori. In addition, vegetables also contain a large amount of vitamin C, which has the effect of lowering blood cholesterol and reducing atherosclerosis, and some vegetables such as celery, water chestnuts, etc. have the effect of lowering blood pressure. 4, reduce the intake of fat, especially animal fat. 5, increase the intake of high-quality protein, such as animal protein (such as fish) and legume protein. Our nutritionists recommend that adults consume 14kg of cereals, 3kg of potatoes, 1kg of eggs, 1.5kg of meat and 0.5kg of fish per person per month. Second, quit smoking and alcohol. Third, lose weight. Fourth, physical exercise. V. Prevention from childhood. We should start to prevent hypertension from childhood, develop good living habits, actively carry out sports and educate about hypertension prevention.
