Vasospasm risk following aneurysmal subarachnoid hemorrhage in older adults

Abstract

This study found that older patients are less likely to develop cerebral vasospasm following aSAH than are younger individuals. Age-associated changes in arteriosclerosis, inflammatory responses, and CSF dynamics may mitigate vascular narrowing in response to aSAH. This finding suggests that the aSAH treatment and vasospasm prevention paradigms should be revised to minimize potentially unnecessary interventions and avoid adverse outcomes for older adults.
