A recent cohort study investigated the spatial and temporal distribution of recurrent intracerebral hemorrhage events, revealing significant findings about the relationship between the event location and underlying conditions, such as cerebral amyloid angiopathy. The study indicates that lobar index ICH and the presence of cerebral amyloid angiopathy at the index event were associated with higher odds of adjacent intracerebral hemorrhage. Additionally, the median time to recurrence was found to be shorter for adjacent events compared to remote events, suggesting that regional, tissue-based factors may facilitate recurrence.
