subarachnoid hemorrhage, the recurrence rate within 3 months of onset was 4.72%, and the recurrence rate within 1 year of onset was 10.25%. The National Cerebral Defense Committee organized a special survey from 2017 to 2018 to follow up 304,935 first-ever stroke patients from 30 provinces and 222 stroke base hospitals, which showed that the recurrence rate of subarachnoid hemorrhage was 4.72% within 3 months of the onset of the disease, and 10.25% within 1 year of the onset of the disease. The overall prognosis of subarachnoid hemorrhage is poor, with a mortality rate as high as 45% and a high disability rate among survivors. The prognosis of subarachnoid hemorrhage is related to the cause of the disease, the location of the hemorrhage, the amount of hemorrhage, the presence of complications, and whether or not the patient receives appropriate treatment. Patients with subarachnoid hemorrhage are advised to seek prompt medical attention.
