Most patients with brain hemorrhage can feel it themselves. Because bleeding in the brain can produce a series of clinical symptoms, patients with mild cerebral hemorrhage can have headache, dizziness, as well as numbness and weakness of the limbs. There are individual patients who do not show symptoms because the amount of bleeding is relatively small and there are no obvious symptoms of neurological deficits at the site of bleeding, which accounts for a relatively small percentage in the clinic. For relatively large amount of bleeding, patients can have headache, dizziness and other symptoms, and it is recommended that patients consult the hospital for head CT examination. For the treatment of cerebral hemorrhage, mainly according to the bleeding site and the amount of bleeding, if the anterior circulation bleeding is less than 30mL, there is no obvious pressure symptoms, can be conservative observation and treatment. If the patient has edema and serious compression symptoms, surgery can be performed if necessary. For cerebral hemorrhage in the posterior circulation is relatively heavy, the patient will have dizziness, walking skewed, limb numbness and weakness and other symptoms, especially bleeding in the brain stem, if more than 5mL, the patient’s life will be seriously threatened.
