Many cerebral infarction before the onset of a short period of time has appeared on one side of the limb weakness or numbness symptoms, accompanied by a sudden unfavorable speech or spitting words. But because the above symptoms often disappear within minutes, head CT examination is normal and not easy to pay attention to. In fact, this is a transient ischemic attack caused by a tiny cerebral thrombus, medically known as a mini-stroke. About half of the patients with mini-stroke will suffer from hemiplegia within 5 years, therefore, it is necessary to attach great importance to mini-stroke and consult the doctor for prevention and treatment as early as possible. The pathological basis of transient ischemic attack also occurs on the basis of cerebrovascular atherosclerosis, only that the degree of lesion is milder and the ischemic time of brain tissue is short. It mostly occurs in the elderly with a history of arteriosclerosis or hypertension. The performance of mini-stroke is the same as the symptoms of stroke aura, which is mainly manifested by the sudden falling of objects in the hand, hemiparesis, hemianopsia, hemianopic sensory disorder, monocular vision disorder, headache and dizziness, tinnitus and difficulty in swallowing, unfavorable language, etc. The difference between mini-stroke and stroke aura is that the symptoms disappear quickly and last from a few minutes to an hour, up to 24 hours, and mini-stroke usually returns to normal within 24 hours. If the brain tissue of a mini-stroke patient is examined, it will be found that there is no brain cell death. After a mini-stroke, the patient's brain cells should be completely normal. If it takes more than 24 hours, the patient will experience brain cell death, which is then a cerebral infarction. The correct attitude towards mini-stroke is that it should be treated like cerebral infarction, and it should be prevented by reliable medication and dietary structure, so as to prevent the "wind" from occurring in the first place, and to be treated in time, so as not to turn into cerebral infarction in the future. People who have had a small stroke should improve the blood supply and oxygenation of brain tissues through reliable medication for a period of time to prevent atherosclerotic plaques from re-forming, and the prevention and treatment medication for small stroke should be the reasonable and concurrent use of anti-platelet aggregation western medicines and blood circulation and blood stasis aroma to open up the mind, lipid-lowering and anti-coagulant traditional Chinese medicines. And small stroke patients in the diet structure should be light, high protein low-fat diet, to reduce blood viscosity, improve the symptoms of atherosclerosis also has a good auxiliary therapeutic effect.
