Smiley Jagadeesan, Angelica Lindsey-Clark, Ugan Reddy

Subarachnoid haemorrhage (SAH) is a critical neurosurgical emergency characterized by high rates of morbidity and mortality. The document outlines the incidence, which is higher in women, and the significant economic burden associated with the condition. It details the aetiology, categorizing SAH into spontaneous and traumatic causes, with cerebral aneurysm rupture being the primary cause of spontaneous SAH. The review also touches upon the key determinants of functional outcome, including early brain injury, rebleeding, and delayed cerebral ischaemia, and emphasizes early management strategies to prevent secondary brain injury.
