TL;DR: An international ad hoc panel of experts involved in subarachnoid hemorrhage research developed and proposed a definition of DCI to be used as an outcome measure in clinical trials and observational studies, which reflect the most relevant morphological and clinical features ofDCI.

TL;DR: Recommendations were developed based on literature review using the GRADE system, discussion integrating the literature with the collective experience of the participants and critical review by an impartial jury and emphasis was placed on the principle that recommendations should be based not only on the quality of the data but also tradeoffs and translation into practice.

TL;DR: Worldwide Subarachnoid hemorrhage incidence and its decline show large regional differences and parallel the decrease in blood pressure and smoking prevalence and may yield a diminished SAH burden.

TL;DR: The data show that the majority of patients with moderate to severe angiographic vasospasm did not have neurological worsening of any cause or cerebral infarction, which suggests that other coexisting factors might be involved in the pathogenesis of delayed cerebral ischemia, which should be an important research target to improve outcome after subarachnoid hemorrhage.

TL;DR: Clinicians can use the UIATS as a comprehensive mechanism for indicating how a large group of specialists might manage an individual patient with a UIA, irrespective of their underlying specialty.
