Cerebral infarction aura: many people have aura performance before the occurrence of cerebral infarction, if good recognition, early prevention, can reduce the occurrence of cerebral infarction. If the following manifestations should be considered as cerebral infarction aura: distant aura: recurrent or persistent headache, dizziness or lightheadedness, memory loss, forgetfulness, numbness of limbs, limb tremors, corner of the mouth twitching, eyelid jumping, nose bleeding, etc., it is necessary to pay attention to the possibility of having cerebral infarction and should be examined in the hospital. Aura signs of impending cerebral infarction When the following phenomena occur, they suggest that cerebral infarction may occur in the near future and need active treatment. It is worth noting that the aura symptoms discussed below are not specific to the aura of cerebral infarction, but can also appear in other diseases. What needs to be noted by the elderly and their families is: once these aura symptoms are found, go to the hospital promptly, do not wait for them, and do not be frightened by them. First, dizziness, sudden aggravation of headache or change from intermittent headache to persistent severe headache. It is generally believed that headache and dizziness are mostly the aura of ischemic cerebral infarction, while severe headache with nausea and vomiting are mostly the aura of hemorrhagic cerebral infarction. Second, a transient black lemon, refers to normal people suddenly appear black in front of the eyes, can not see objects, a few seconds or a few minutes to return to normal, neither nausea, dizziness, nor any impairment of consciousness. This is due to transient retinal ischemia, suggesting intracranial hemodynamic changes or temporary blockage of retinal arteries by tiny blood clots, which is the earliest alarm signal of cerebrovascular disease. Third, transient visual impairment, which is manifested as blurred vision or visual field defect and incomplete seeing, this phenomenon mostly recovers on its own within an hour, and is an earlier forecast signal of cerebral infarction. Language and mental changes, such as difficulty in pronunciation, aphasia, difficulty in writing; sudden personality change, silence, indifferent expression or impatience, irritability, or transient judgment or intellectual impairment, drowsiness. V. Other aura manifestations, such as nausea and vomiting or choking, or blood pressure fluctuation with dizziness or tinnitus, unexplained recurrent nasal clumsy blood, often as a recent precursor of hypertensive cerebral clumsy blood. Sixth, sleepiness and drowsiness, manifesting as yawning after yawning? It is the reaction of brain hypoxia, especially the respiratory center hypoxia. With the aggravation of cerebral atherosclerosis, the arterial lumen becomes narrower and narrower, and cerebral ischemia deteriorates seriously? 80% of people yawn frequently 5 to 10 days before the onset of ischemic cerebral infarction. Therefore, do not ignore this important alarm signal. Seven, somatic sensory and motor abnormalities, such as episodic unilateral limb numbness or weakness, loss of hand grip on objects, unexplained fainting or falling, and unilateral facial palsy that lasts for less than 24 hours. Follow-up observation, 3 to 5 years after the occurrence of such phenomena, about half of them occur ischemic cerebral infarction. Eight, razor landing phenomenon, refers to the stubble shaving process, when the head turned to the side, suddenly feel the arm holding the razor weakness, razor landing, can be accompanied by slurred speech, but in 1 ~ 2 minutes or so completely back to normal. This is due to the fact that when the neck is turned, the degree of stenosis of the already sclerotic carotid artery is aggravated, resulting in insufficient blood supply to the skull and brain, and transient cerebral ischemia occurs. It suggests that ischemic cerebral infarction may occur at any time. Expert tip: Once symptoms are detected, attention should be paid to early detection, early diagnosis and early treatment. Choosing the right treatment is the key, do not have a disease and cause serious injury. It is recommended to go to a regular public hospital for standardized treatment so that patients can recover as soon as possible.
