Although cerebrovascular disease has a rapid onset, many patients have some early signs 1-2 days or hours before the onset of the disease, which are medically known as “stroke aura”. At this time, if we can identify and treat them in a timely manner, we can turn the crisis into safety and prevent the occurrence of cerebrovascular disease. What are the aura symptoms of cerebrovascular disease? 1. Suddenly, the mouth and eyes are distorted, the corners of the mouth salivate, speech is unclear, spitting difficulty in aphasia or language, 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, 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 some people may experience dizziness in front of the eyes or have difficulty seeing for a while, tinnitus or hearing changes. This is due to insufficient blood supply to the cerebral vessels and affects the sensory function of the brain. 4. Disorders of consciousness, mental depression, sleepiness or drowsiness. 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, general fatigue, weakness, sweating, low fever, chest tightness, palpitations or sudden eruption, vomiting, etc., which are the manifestations of vegetative nerve dysfunction. The above symptoms may not be present in every patient, but as long as there is an aura, it is a stroke alarm for the middle-aged and elderly, 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.
