Transient ischaemic attack (TIA) is the sudden onset of focal neurological dysfunction of presumed vascular origin that, by definition, resolves within 24 hours (usually much sooner). Its importance as a predictor of completed stroke has only recently been recognised. The ABCD (2) score predicts severity of recurrent events after TIA, high scores being associated with major recurrent stroke and low scores with high rates of recurrent TIA, which have implications for cost-benefit analyses of policies on hospital admission for patients with high scores and for the advice given to patients with low scores. In a quite high proportion of patients with recent symptoms of transient ischemic attack, DWI may help in the diagnosis of ischemic stroke and in shedding light on the underlying pathogenic mechanism. Updated guidance on the recognition and management of TIA has recently been published as part of the National Clinical Guideline for Stroke. This is a concise version of the TIA component of the full guideline that recommends an urgent response to TIA to prevent subsequent stroke.
