Summary
The ABCD2 score is a validated clinical tool that estimates the short-term risk of stroke following a transient ischemic attack (TIA). It assigns points across five parameters — Age, Blood pressure, Clinical features, Duration of symptoms, and Diabetes — to produce a total score between 0 and 7. Higher scores correspond to greater 2-day stroke risk, helping clinicians prioritize urgent evaluation and treatment.
How it works
- Select the patient's age category (under 60 or 60 and older).
- Indicate whether systolic BP was 140 mmHg or higher, or diastolic 90 mmHg or higher.
- Choose the most prominent clinical feature: unilateral weakness, speech disturbance without weakness, or other.
- Select the duration of TIA symptoms (under 10 minutes, 10–59 minutes, or 60 minutes or longer).
- Indicate whether the patient has a history of diabetes.
- The score (0–7) and corresponding 2-day stroke risk percentage are displayed instantly.
Use cases
- Emergency department triage after a suspected TIA.
- Determining urgency of neurology referral or hospital admission.
- Educational reference for medical students learning TIA risk stratification.
- Quick bedside risk communication with patients and families.
- Supporting documentation in clinical case notes.
- Comparing risk across multiple patients in a teaching scenario.
