Smoke disease is a cerebrovascular disease in which the blood vessels at the base of the brain become abnormal. Smoke disease is serious and can directly endanger life and health, so we should actively prevent it. However, many people do not know how to prevent it effectively. The most common early symptoms of smog are headache and dizziness, but there are many diseases that can cause headache and dizziness, so it is important to do the relevant screening as early as possible. The purpose of screening is to eliminate various causes of headache and dizziness (other than smog), such as neurogenic headache caused by psychiatric factors, brain tumor caused by intracranial occupational lesions, and headache caused by cerebrovascular disease. In addition, smog has a certain degree of heredity, so people with a family history of smog should pay attention to the symptoms of headache, dizziness, and weakness of the limbs and go to the hospital for screening as soon as possible. At present, magnetic resonance angiography is a less expensive and more effective screening method, which is a minimally invasive test and can accurately and clearly see the vascular lesions. Finally, it is worth reminding people that the prevention of smog should also start from the daily routine and diet. In particular, patients with smog disease should pay attention to hygiene in their diet, avoid spicy and stimulating food, avoid eating too cold and too hot food, moderate and light, no partial diet, diet should be high protein, high vitamin, low fat, easy to digest food (such as fish, lean meat, eggs, vegetables, fruits, etc.) is appropriate. On work and rest, pay attention to rest, do not overwork, do not do high-intensity exercise, try to develop a good work and rest routine.
