Cerebral hemorrhage is an acute, serious brain disease that can cause physical dysfunction and even death if not treated promptly. The precursors of a cerebral hemorrhage will be a sharp increase in blood pressure and a relatively severe headache, and a few patients will have seizures. The precursors of a cerebral hemorrhage should be relatively short because the process of a cerebral hemorrhage attack is very rapid. The patient’s blood pressure often rises above the patient’s usual blood pressure, the headache is tearing or explosive, and loss of consciousness can easily develop, and vomiting can be violent and jet-like. If the patient has a history of hypertension, or hyperlipidemia or diabetes, the patient should pay high attention to the possibility of cerebral hemorrhage once he has a severe headache, significantly elevated blood pressure, and rapid onset of limb paralysis or impaired consciousness. Especially, the incidence of cerebral hemorrhage in elderly patients is relatively high and the mortality rate is also very high. Therefore, if there are precursors of cerebral hemorrhage, such as the above symptoms, it is still necessary to further examine and actively intervene if necessary, especially to measure blood pressure and observe whether there is more violent vomiting, which are signals suggesting cerebral hemorrhage, but the main thing is to confirm the diagnosis by neurology examination, especially emergency CT examination.
