ABCD2 score

Age, Blood pressure, Clinical features, Duration, Diabetes [ABCD2] score for stroke risk after TIA Indications: - used to predict risk of stroke after transient ischemic attack (TIA) Procedure: Age: - O if < 60 years - 1 if >= 60 years Blood Pressure: - 1 if systolic BP >140 mm Hg &/or diastolic BP >90 mm Hg Clinical Features: - 0 if no speech disturbance or weakness - 1 if speech disturbance without weakness - 2 if unilateral weakness Duration: - 0 if < 10 minutes - 1 if 10-59 minutes - 2 if > 59 minutes Diabetes mellitus: - 0 if non-diabetic - 1 if diabetic Interpretation: - maximum score is 7 - score > 2 is associated with significantly increased risk of stroke within 90 days of TIA [4] - no ABCD2 score cutoff reliably predicts TIA patients at risk for stroke Clinical significance: - patients with TIA & ABCD2 score >= 3 should be hospitalized
