The precursors of a cerebral hemorrhage are a sudden headache, flushing, and a sharp rise in blood pressure measurements. The manifestations of cerebral hemorrhage are related to the amount of bleeding, and the main symptoms are dementia, numbness or coma. Cerebral hemorrhage, or bleeding in the brain, can be preceded by headache, flushing, and fluctuating blood pressure in a few patients. Sometimes the precursor symptoms are not obvious, and when the precursor is not observed, the blood vessel may have ruptured and bled. Therefore, it is important to keep blood pressure and emotions under control to prevent a sudden rise in blood pressure after a major stimulus, which can lead to a major illness within minutes. The severity of the cerebral hemorrhage manifestation depends largely on the amount and location of the bleeding, which can include headache, vomiting, and paralysis of the limbs. When the bleeding is small, numbness of the limbs may occur. However, if the bleeding is excessive and uncontrollable, it may lead to coma or even death. Cerebral hemorrhage is a serious disease after the onset of the disease, if the above precursors and symptoms manifest, you need to seek medical attention in time.
