Read time: 1 mins
Last updated:16th Aug 2019

This guideline covers interventions in the acute stage of a stroke or transient ischaemic attack (TIA). It offers the best clinical advice on the diagnosis and acute management of stroke and TIA in the 48 hours after onset of symptoms.

A stroke occurs when the blood supply to a part of the brain is acutely compromised. Most strokes (85%) are caused by a blockage in a blood vessel (artery) that supplies blood to the brain. A TIA or 'mini stroke' has the same clinical presentation as a stroke except that symptoms disappear within 24 hours.
