Stroke (acute cerebrovascular disease), commonly known as stroke, is an obstruction or rupture of a cerebral blood vessel that causes impaired cerebral blood circulation and functional and structural damage to brain tissue, and is divided into two categories: ischemic stroke and hemorrhagic stroke. Stroke is the first cause of disability and one of the leading causes of death in adults. 1. Common symptoms before a stroke: The most common symptom of a stroke is usually sudden weakness of the face, arm or leg on one side of the body. Other symptoms include numbness, especially on one side of the face, arm or leg; confusion, difficulty speaking or understanding; difficulty recognizing objects in one or both eyes; difficulty walking, dizziness, loss of balance or coordination; severe headache with no cause; weakness or loss of consciousness. People who experience these symptoms should seek immediate medical attention. Eighty percent of strokes are preventable. A healthy diet, regular exercise and no use of tobacco products are the keys to success. These three simple measures will not only significantly reduce the chance of a stroke, but will also help prevent most type 2 diabetes and chronic respiratory diseases, as well as certain types of cancer. (1) Avoid tobacco use: Whether it’s paper cigarettes, cigars, pipes or chewing tobacco, tobacco is bad for your health. Exposure to secondhand tobacco smoke is also dangerous. The good news is that the risk of stroke begins to decline immediately after people stop using tobacco products and can drop by as much as half after one year. (2) Healthy diet: A balanced diet is essential for a healthy cardiovascular system: include plenty of fruits and vegetables, unprocessed grains, lean meats, fish and legumes, and limit salt, sugar and fat intake. (3) Regular physical exercise: at least 30 minutes of regular physical exercise every day helps maintain cardiovascular health; at least 60 minutes on most days helps maintain a healthy weight. 2, stroke prevention: (1) timely treatment of diseases that may cause stroke, such as atherosclerosis, diabetes, coronary heart disease, hyperlipidemia, hyperviscosity, obesity, cervical spondylosis, etc. Hypertension is the most dangerous factor for the occurrence of stroke and a central part of stroke prevention. Blood pressure should be effectively controlled, long-term medication should be adhered to, and changes in blood pressure should be observed for a long time for timely treatment. (2) Pay attention to the aura signs of stroke, such as dizziness, headache, numbness of limbs, drowsiness and drowsiness, and abnormal personality. Once a mini-stroke strikes, you should go to the hospital in time for treatment. (3) Eliminate the precipitating factors of stroke, such as mood swings, excessive fatigue, and excessive force. Pay attention to psychological prevention, keep a happy spirit and emotional stability. Promote a healthy lifestyle, regular routine, and keep bowel movements smooth to avoid a sharp rise in blood pressure due to forceful defecation, which can trigger cerebrovascular disease. (4) Diet should have a reasonable structure, low salt, low fat, low cholesterol, appropriate more soy products, vegetables and fruits, quit smoking, alcohol and other bad habits. Eat fish at least three times a week, especially fish rich in omega-3 fatty acids, or take deep-sea fish oil. omega-3 fatty acids can regulate the state of the blood, making it less likely to form clots, which in turn prevents brain infarction. (5) Outdoor activities (especially for the elderly) should pay attention to warmth. You should gradually adapt to the ambient temperature indoors, adjust the indoor air conditioning temperature, which should not be too high, and avoid a sudden shift from a higher temperature environment to a lower temperature outdoors. In addition, stroke patients should also pay attention to be more careful when going out, to prevent falls; get up, head down to tie shoelaces and other daily movements should be slow; bath time should not be too long, etc. I hope you know more about the symptoms of stroke before the attack, in order to do a good job of timely prevention, stroke patients in daily life, must pay attention to a healthy diet, to need more exercise, less smoking and drinking.
