Cerebral thrombosis, is it far from us? Cerebral thrombosis not only affects the physical and mental health of patients, but also leads to paralysis in serious cases. So, what are the precursors of cerebral thrombosis? What are the symptoms of cerebral thrombosis? 1.Yawning continuously 80% of people suffering from ischemic cerebral thrombosis will have yawning continuously 5-10 days before the onset of the disease. 2, abnormal blood pressure When blood pressure suddenly and continuously rises above 200/120mmHg, it is the precursor of cerebral thrombosis; when blood pressure suddenly drops below 80/50mmHg, it is the precursor of cerebral thrombosis. 3. Nasal bleeding in hypertensive patients This is a danger signal that deserves attention. Several times of massive nosebleeds, coupled with bleeding from the fundus and hematuria, such a person may develop cerebral thrombosis within six months. 4. Abnormal gait Stumbling gait and walking leg weakness is one of the precursor symptoms of hemiplegia. If the gait of the elderly suddenly changes and is accompanied by numbness and weakness of the limbs, it is a precursor sign of cerebral thrombosis. 5.Sudden onset of vertigo Vertigo is an extremely common symptom of cerebral thrombosis, which can occur at any time before cerebrovascular disease, especially in the early morning when waking up. In addition, it also occurs easily after fatigue or bathing. Especially in hypertensive patients, if vertigo occurs repeatedly more than 5 times in 1 to 2 days, the risk of cerebral hemorrhage or cerebral infarction increases. 6. Sudden onset of severe headache Any sudden onset of severe headache; accompanied by convulsive seizures; recent history of head trauma; accompanied by coma and drowsiness; sudden changes in the nature, location and distribution of headache; headache aggravated by coughing and exertion; severe pain that can wake up in pain at night.
