Overview
Epidemiology and demographics
=Incidence
- The incidence of subarachnoid hemorrhage was estimated 10.5 per 100 000 person years.[1]
Age
- Subarachnoid hemorrhage (SAH)usually occurs at a relatively young age
- The incidence of aneurysmal subarachnoid hemorrhage (aSAH) increases with age and commonly affects adults ≥50 years of age.[2]
Gender
- Women are slightly more affected with aneurysmal subarachnoid hemorrhage (SAH) than men (1.24 times higher than in men).[2][3]
Race
- Subarachnoid hemorrhage usually affects individuals of African Americans populations.[4]
- The incidence of aneurysmal subarachnoid hemorrhage (SAH) is higher in Blacks and Hispanics compere to white Americans.
Geographic region
- In the United States, the incidence of aneurysmal subarachnoid hemorrhage (SAH) is 10 to 15 cases per 100,000 population.[5]
- In China, the incidence of aneurysmal subarachnoid hemorrhage (SAH) is 2 cases per 100,000 population.[6]
- In South and Central America, the incidence of aneurysmal subarachnoid hemorrhage (SAH) is 4 cases per 100,000 population.[7]
- In Finland and Japan, the incidence of aneurysmal subarachnoid hemorrhage (SAH) is 19 to 23 cases per 100,000 population. [8]
Case fatality rate=
- The 30-day case fatality rate of subarachnoid hemorrhage (SAH) is 32,000 cases per 100,000 individuals.[9]
