Around 25% of patients with subarachnoid haemorrhage (SAH) experience deterioration in the days following stroke, often as a result of delayed cerebral ischaemia (DCI). These deficits have been principally attributed to cerebral vasospasm, but recent studies suggest a role for dysfunction of cerebral autoregulation in post-SAH DCI. Budohoski et al. discuss recent findings on cerebral autoregulation, and present an overview of the pathophysiology and stages of autoregulatory impairment that occur following SAH.
