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 mainly include: 1. Suddenly, the eyes and mouth are distorted, the corners of the mouth salivate, speech is unclear, spitting difficulty, aphasia or language does not reach the meaning, swallowing difficulty, weakness or inflexibility of one limb, unstable walking or sudden fall. This is caused by insufficient blood supply and motor nerve dysfunction due to cerebrovascular disease. 2. Sudden onset of severe headache, dizziness, or even nausea and vomiting, or the form and feeling of headache and dizziness is different from the previous days, and the degree is aggravated, or from intermittent to continuous. These signs indicate fluctuations in blood pressure, or brain dysfunction, and are precursors of cerebral hemorrhage or subarachnoid hemorrhage. 3. Numbness of the face, tongue, lips or limbs, or haziness in front of the eyes or momentary difficulty in seeing, tinnitus or change in hearing. This is due to the lack of blood supply to the cerebral vessels and affects the sensory function of the brain. 4. Disorders of consciousness, mental depression, sleepiness or drowsiness 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. 5. Fatigue and weakness, sweating, low fever, chest tightness, palpitation or sudden eruption, vomiting, etc., which are the manifestations of vegetative nerve dysfunction. The above symptoms may not be manifested by every patient, but as long as there are aura symptoms, it is a stroke alarm for middle-aged and elderly people, so 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 be treated in place. If necessary, the patient should be sent to the hospital with the patient lying flat.
