ABCD score

ABCD score

A clinical testing instrument used outside of a hospital setting for people at high risk of stroke after a transient ischaemic attack.

ABCD score calculation
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).

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

ABCD score

A clinical prediction value that estimates the likelihood of stroke in a patient who has had a transient ischemic attack. Its elements include: A (age greater than or less than 60); B (blood pressure above 140 mm Hg systolic or 90 diastolic); C (clinical features such as one-sided body weakness or speech disturbance); and D (duration of symptoms: 60 min, 10-60 min, or less than 10 min).
Synonym: ABCD prediction rule; ABCD rule
