Cerebral hemorrhage usually starts rapidly, with an onset time of minutes or hours, but it has a gradual developmental evolution. In the early stages of the disease, some abnormalities are more or less present, i.e., some precursory manifestations with aura. In 50% of patients with cerebral hemorrhage, aura symptoms are present. The risk of cerebral hemorrhage in the first year after the onset of aura is high, especially in the first two months. Once these aura manifestations appear in a patient with hypertension, it is a sign that a brain hemorrhage is about to occur or is already in the prodromal stage. At this time, if you can observe carefully, you can detect the abnormalities in time and go to the hospital to compete for treatment, so as to control the development of the disease and avoid serious consequences. In summary, the common precursor symptoms of cerebral hemorrhage are: 1. Suddenly feeling numbness, weakness, inconvenience in moving one side of the body, dropping objects in hand, distorted mouth, salivation, and unstable walking. 2.Suddenly unable to speak when talking with others, or slurring words, or unable to understand others’ words. 3.Temporary blurred vision, which may return to normal later on its own, or blindness may occur. 4. Sudden dizziness, rotation of surrounding objects, unsteadiness or even fainting on the ground. These manifestations may appear once briefly, or may occur repeatedly or gradually worsen. When the above-mentioned aura symptoms appear, patients should pay high attention to them in their minds, but not too nervous.
