Although the onset of cerebrovascular disease is rapid, many patients have some early signs 1 to 2 days or hours before the onset of the disease, which are medically known as “stroke aura”. At this time, if timely recognition and active and effective treatment can be carried out, the patient can turn the crisis into peace and prevent the occurrence of cerebrovascular disease. The aura symptoms of cerebrovascular disease are: 1. Suddenly, the mouth and eyes are slanted, drooling, slurred speech, difficulty in spitting, aphasia or incoherence, choking and coughing, weakness or inflexibility of one limb, unstable walking or sudden fall. This is caused by insufficient cerebrovascular blood supply and motor dysfunction. 2. 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 the lack of blood supply to the brain and affect the sensory function of the brain. 3. Disorders of consciousness, performance of mental depression, always want to sleep or drowsy all day. The personality is also uncharacteristic, suddenly becoming silent, indifferent expression, slow action or talkative, 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 eruption, vomiting, etc., which are manifestations of vegetative nerve dysfunction. The above symptoms may not be manifested in every patient, but as long as there are aura symptoms appear, especially in middle-aged and elderly people, they should be especially alert. At this time, the patient should be kept quiet, rest in bed in time, avoid mental tension, move as little as possible, and preferably treated in situ. If necessary, send the patient to hospital for consultation and treatment.
