As the quality of life improves and the pace of life accelerates, many people, especially middle-aged and elderly people, often have recurrent symptoms of dizziness, dizziness and headache, and also have heartburn, tinnitus, impatience and irritability, insomnia and dreaminess, memory loss, inattention and forgetfulness, which are all the results of long-term cerebral blood supply deficiency. There are many causes of insufficient blood supply to the brain, including anemia, heart disease (such as arrhythmia, cardiac insufficiency, etc.), lung disease (emphysema, pulmonary insufficiency), hypertension, dyslipidemia, diabetes, increased blood viscosity (hyperlipidemia, thrombocythemia, etc.), cervical spondylosis, etc., in addition to physical and poor lifestyle habits (such as overweight and obesity, smoking and alcoholism, lack of physical activity, unreasonable diet, etc.) Organic lesions. This leads to microthrombosis and vascular sclerosis in some cerebral arteries, resulting in narrowing of the vascular lumen or vascular spasm, chronic and widespread cerebral ischemia and hypoxia, and a series of clinical manifestations of brain dysfunction. If there is sudden dizziness, numbness of hands and feet, slurred speech or speechlessness, unstable walking or sudden fainting, it is mostly the result of acute attack of cerebral blood supply deficiency. If there are recurrent episodes of dizziness, headache, drowsiness all day long, always wanting to sleep, or silent, talkative and impatient, insomnia and dreaminess, memory loss, inattention, which cannot be relieved and improved even after sufficient rest, it is mostly the manifestation of chronic cerebral insufficiency of blood supply. Domestic and foreign medical doctors have also found that most middle-aged and elderly people are found to have vascular spasm in cerebral blood flow examination; plaque formation and vascular stenosis in carotid ultrasound examination, suggesting that there was evidence of “Alzheimer’s disease” and “cerebral infarction” before the onset of the disease. Evidence of long-term chronic cerebral blood supply deficiency. If chronic cerebral insufficiency is not treated in a timely manner, it may also lead to the occurrence of Alzheimer’s disease and cerebral infarction. Therefore, chronic cerebral insufficiency is also known as the “invisible killer” that threatens the health of middle-aged and elderly people! Prevention: Prevention methods for cerebral insufficiency can be found everywhere on the Internet and in books, but the main thing is to arrange work and rest time reasonably, avoid mood swings, adjust the diet structure (light, do not refuse meat, balanced consumption of red and white meat), active physical exercise, moderate movement of the neck and waist, weight control, but not excessive exercise. Because everyone’s working life environment is different, the above methods are not very operable and difficult to adhere to. Therefore, it is still necessary to arrange exercise time reasonably according to one’s own situation (such as walking, jogging, playing tai chi, etc.). In addition, middle-aged and elderly people should regularly measure blood pressure, electrocardiogram, brain ultrasound, as well as blood routine, blood sugar, blood lipids, blood viscosity, clotting time, neck MRI and other tests to prevent problems before they occur. Treatment: 1, first remove risk factors: such as quit smoking and alcohol, maintain a good state of mind and adequate sleep (smoking and alcohol is difficult to quit eating less is appropriate, mood is best to take a walk), diet plus drugs to control blood pressure, blood sugar, blood lipids, arrhythmias, etc., to improve cardiopulmonary function; 2, take anti-platelet drugs: the first choice of aspirin or clopidogrel (Taiga), can effectively inhibit platelet coagulation into clots, good for blood circulation , which is beneficial to the blood supply of the brain. 3, anti-coagulant drugs: anti-coagulant drugs and anti-platelet drugs have the same effect, both can make the blood flow smoothly, increase the blood supply to the brain, reduce the attack of cardiac and cerebral ischemia. But taking is to pay attention to regular recheck out the clotting time, clotting time prolongation should follow medical advice to reduce or stop the drug to avoid inducing cerebral hemorrhage. 4, only a small number of patients need surgical treatment: if the carotid artery has severe stenosis (more than 70%), carotid endarterectomy or carotid stenting into shape can be used. In clinical practice, because some elderly patients combined with a variety of underlying diseases, taking as many as three or four kinds of Western drugs, or even more than five or six kinds, for one thing, it is difficult for patients to adhere to take medication on time, and then it is difficult to clarify the interaction between multiple drugs from pharmacology. The antagonism between drugs may be one of the reasons for the poor efficacy of western drug therapy. At this time, if the patient is dialectic according to different conditions, and use different Chinese medicine for conditioning, not only can reduce the toxic side effects between drugs, but also can receive satisfactory results. Especially for patients with multiple underlying diseases, such as hypertension, hyperlipidemia and cervical spondylosis, herbal treatment may be more effective than western medicine alone.
