Cerebral infarction is usually rapid in onset, but many patients have some early signs 1 to 2 days or hours before the onset, which are medically called “stroke aura”. At this time, if timely recognition and active and effective treatment can be carried out, the patient can mostly turn the crisis into safety and prevent the occurrence of cerebral infarction. The aura symptoms of cerebral infarction mainly include: 1. Transient slanting of the mouth and eyes, drooling, slurred speech, difficulty in spitting out words, incomprehension of speech or incomprehension of other people’s speech, choking and coughing on drinking water, weakness or inflexibility of one limb, unstable walking or sudden fall. This is caused by insufficient cerebrovascular blood supply and motor dysfunction. 2. Transient numbness of the face, tongue, lips or limbs, and also some manifest haziness in front of the eyes or momentary difficulty in seeing things, tinnitus or hearing changes. This is due to insufficient blood supply to the brain and affects the sensory function of the brain. 3, mental depression, always want to sleep or drowsy all day. The personality is also uncharacteristic, suddenly becoming silent, indifferent in expression, slow in action or talkative and irritable, and some have transient loss of consciousness, which is also related to cerebral ischemia. 4, general fatigue, weakness, sweating, low fever, chest tightness, palpitations or sudden appearance of erratic, vomiting, etc., which are the manifestations of plant nerve dysfunction. The first two of the above symptoms are more common, and these symptoms may not be present in every patient, but as long as there are aura symptoms, especially in middle-aged and elderly people, they should be especially alert. At this time, the patient should be kept quiet, avoid mental tension, and be sent to the doctor in time.
