A simple score (ABCD2) to identify individuals at high early risk of stroke after transient ischemic attack.
-
A (Age); 1 point for age >60 years,
-
B (Blood pressure > 140/90 mmHg);1 point for hypertension at the acute evaluation,
-
C (Clinical features); 2 points for unilateral weakness, 1 for speech disturbance without weakness, and
-
D (symptom Duration); 1 point for 10–59 minutes, 2 points for >60 minutes.
-
D (Diabetes); 1 point
Total scores ranged from 0 (lowest risk) to 7 (highest risk).
Stroke risk at 2 days, 7 days, and 90 days:
-
Scores 0-3: low risk
-
Scores 4-5: moderate risk
-
Scores 6-7: high risk
