What are the potential impacts of increasing age on aSAH survival rates?
Studies have demonstrated that increasing age can have a negative impact on survival rates for patients presenting with aSAH. Additionally, studies suggest that higher mortality rates occur in women than men, and higher mortality rates occur in certain racial/ethnic groups (blacks, American Indians/Alaskan Natives, and Asians/Pacific Islanders) than in whites. Furthermore, multiple studies have consistently demonstrated that intellectual impairment is very prevalent after aSAH, and scales that are relatively insensitive to cognitive impairment, behavioral changes, social readjustment, and energy level may substantially underestimate the effect of aSAH on the function and quality of life of surviving patients.
