ABCD2 score

A clinical testing instrument used outside of a hospital setting for people at high risk of stroke after a transient ischaemic attack, which recognises the importance of diabetes in rating risk of strokes.

A: Age (≥ 60 years, 1 point);
B: Blood pressure at presentation (≥ 140/90 mmHg, 1 point);
C: Clinical features (unilateral weakness, 2 points; speech disturbance without weakness, 1 point);
D: Duration of symptoms (≥ 60 minutes, 2 points; 10— 59 minutes, 1 point);
Presence of diabetes (1 point).

Total scores range from 0 (low) risk to 7 (high) risk.

Johnston and others have established that roughly 34% of TIA patients have an ABCD2 score of 0-3, putting them in a low short-term risk category, with an associated 1% risk of stroke within the first 2 days after their TIA.
If patients agree, they answer a 26-item questionnaire that incorporates the ABCD2 score, as well as questions that give some hint about the brain territory affected.
