General description
A transient ischemic attack (TIA) is a temporary period of symptoms similar to a stroke, resulting from a temporary disruption in blood flow to the central nervous system, that doesn't cause permanent damage. However, there is an increased risk of stroke following TIA – in about a quarter of stroke patients, a TIA has preceded a stroke.
The ABCD² score is a seven-point risk-stratification tool developed to identify patients at high risk of stroke following a TIA. It is based on the combination of 5 variables: Age, Blood pressure, Clinical features, Duration and Diabetes - ABCD². The resulting scores stratify the patients into low (0–3 points), moderate (4–5 points) and high (6–7 points) risk categories. For each of the categories a 2-, 7- and 90-day stroke risk estimation is given.
The ABCD² score was created by Johnston et al. by merging two previously validated clinical decision rules – the ABCD and the California scores. It has been externally validated and is endorsed by the European Stroke Organisation (ESO) and American Heart Association (AHA) guidelines as one of the TIA risk stratification scores.
The ESO guidelines on management of TIA use ABCD² score of ≥ 4 to define high risk TIA. They also recommend against using prediction tools (like ABCD² score) alone to identify high risk patients or to make triage and treatment decisions in suspected TIA patients due to limited sensitivity.
