The claim that the 6 signs are precursors to cerebral thrombosis is inaccurate and not true. 6 signs are precursors to cerebral thrombosis does not exist in clinical practice. The precursors of cerebral thrombosis are not necessarily 6, the precursors of cerebral thrombosis are as follows: Cerebral artery embolism due to cardiovascular lesions, changes in blood composition, age and emotion is called cerebral thrombosis. Patients with cerebral thrombosis usually have symptoms or precursors of the disease such as numbness and weakness of the limbs, slurred speech, slow reaction, tremor of the limbs, blurred vision, vertigo and so on. Therefore, the six signs of cerebral thrombosis precursor statement is not accurate. When the patient has numbness and weakness of the limbs, slurred speech and other symptoms need to consult a doctor in a timely manner, under the guidance of the doctor to carry out the appropriate examination, to exclude related diseases, so as to achieve symptomatic treatment.
