In this episode, Dr Roger Henderson looks at one of the most time-sensitive diagnoses in general practice: the transient ischaemic attack, or TIA. Often underestimated because symptoms resolve quickly, a TIA is in fact a powerful warning sign of an impending ischaemic stroke. For GPs, recognising and responding to this brief neurological event can make the difference between prevention and long-term disability. Here we break down the modern tissue-based definition of TIA, highlighting how it differs from older time-based concepts and why that matters in our clinical practice. We also explore the importance of sudden focal symptoms and discuss why the first 48 hours carry the greatest risk. We also look at key causes and outline practical approaches to urgent evaluation, risk stratification and management.
