Transient ischaemic attack: the ‘funny do’ that is no joke

How do you recognise a transient ischaemic attack (TIA) and how does this differ from a full stroke? In this article, we explore the ABCD2 score, which can be used to identify high- and low-risk TIAs, and the best course of action if a TIA is suspected. A TIA is very often the herald of a more serious and permanent stroke, underlining why it should be acted on as a matter of urgency, and there is an update on the current guidance from NICE and the Royal College of Physicians.
