Overview
The incidence of subarachnoid hemorrhage was estimated 10.5 per 100 000 person annually.[1] 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]
Epidemiology and demographics
Incidence
- The incidence of subarachnoid hemorrhage was estimated 10.5 per 100 000 person annually.[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]
- The mean age of perimesencephalic nonaneurysmal Subarachnoid hemorrhage|subarachnoid hemorrhage (PM-NASAH) occurrence was reported between 50 and 55 years.[3]
Gender
- Women are slightly more affected with aneurysmal Subarachnoid hemorrhage|subarachnoid hemorrhage (SAH) than men (1.24 times higher than in men).[2][4]
- Unlike aneurysmal subarachnoid hemorrhage (SAH), the incidence of perimesencephalic nonaneurysmal subarachnoid hemorrhage (PM-NASAH) does not vary by gender.[3]
Race
- The incidence of aneurysmal subarachnoid hemorrhage (aSAH is higher in Blacks and Hispanics compere to white Americans.[5]
Geographic region
- In the United States, the incidence of aneurysmal subarachnoid hemorrhage (aSAH) is 10 to 15 cases per 100,000 population.[6]
- In China, the incidence of aneurysmal aneurysmal subarachnoid hemorrhage (SAH) is 2 cases per 100,000 population.[7]
- In South and Central America, the incidence of aneurysmal subarachnoid hemorrhage (aSAH) is 4 cases per 100,000 population.[8]
- In Finland and Japan, the incidence of aneurysmal aneurysmal subarachnoid hemorrhage (SAH) is 19 to 23 cases per 100,000 population. [9]
Case fatality rate
- An average case fatality rate of subarachnoid hemorrhage (SAH) was estimated to be 50,000 cases per 100,000 individuals.[10][11]
- 10,000 cases per 100,000 individuals die prior reaching the hospital
- 25,000 cases per 100,000 individuals die within 24 hours of SAH
- 45,000 cases per 100,000 individuals die within 30 days of SAH
