The ABCD2 score is calculated by adding the following A (age): ≥ 60 = 1 B (blood pressure): Systolic blood pressure ≥ 140 and / or diastolic blood pressure > 90 = 1 C (clinical features): Weakness = 2, speech disturbance without weakness = 1 D (TIA duration): ≥ 60 min = 2, 10 to 59 min = 1, < 10 minutes = 0 D2 (diabetes) = 1 Risk of stroke within 2 days based on the ABCD2 score is about For a score of 6 to 7: 8% For a score of 4 to 5: 4% For a score of 0 to 3: 1% If patients have had a TIA or minor stroke, clopidogrel plus aspirin given within 24 hours of symptom onset and continued for 21 days appears more effective than aspirin alone for reducing risk of stroke in the first 90 days and does not increase risk of hemorrhage (8).
