Cerebral hemorrhage is usually acute, sudden, and the early symptoms are not very obvious. But if the early symptoms are obvious, we should beware of the brain hemorrhage coming, so what are the more obvious symptoms that will appear in the early stage of brain hemorrhage? Sudden headache, dizziness, nausea, vomiting, eye swelling, eye pain, unsteadiness or even fainting; sudden loss of fluency in speech, slurred words, or incomprehension of other people’s words, distorted mouth, salivation, tongue extension; unilateral body numbness, weakness, difficulty in moving, unstable holding, walking; temporary blurred vision, blackness in front of the eyes, sometimes can return to normal on its own In severe cases, blindness may occur. The development of CTA, MRA and DSA (digital subtraction angiography) technology has enabled a more early and timely understanding of the carotid artery and cerebrovascular situation, and the results of DSA examination are the gold standard for determining cerebrovascular lesions.
