ABCD2 Score

Validated Triage Tool • Assessment of Early Stroke Risk after TIA

ABCD2 Score for TIA Stroke Risk Assessment (ABCD2)

Clinical Features (Choose one)

Duration of Symptoms (Choose one)

Risk Assessment Active

Select clinical criteria to generate TIA stroke-risk estimates.

Guidelines & Evidence

Verified

Last Review: 2026

When to Use

Initial risk stratification for patients with suspected Transient Ischemic Attack (TIA).

Triage tool to identify patients at high risk of early stroke (within 48 hours, 7 days, and 30 days).

Decision support for hospital admission vs. outpatient evaluation.

Long-term prognosis (up to 4 years) for recurrent stroke and mortality in patients with TIA or minor ischemic stroke (NIHSS < 3).

Epidemiology of TIA

Nearly 240,000 TIAs occur annually in the US. The risk of stroke after TIA is historically significant: 2–4% at 48 hours, 6% at 7 days, and 10–15% at 90 days. Aggressive urgent treatment has been shown to reduce these rates significantly (EXPRESS study).

Patient Selection

Ideally applied to patients presenting within 48–72 hours of symptom onset. The score was validated in population-based cohorts (e.g., Rochester Epidemiology Project) and large clinical registries.

Critical Safety Warning

A substantial proportion of strokes (up to 25% at 7 days) occur in patients with "low" or "intermediate" risk scores (ABCD2 ≤ 4). Do not use the score in isolation to discharge a patient without neurovascular imaging (MRI/DWI).

Related Scores in Practice

In clinical practice, this assessment is frequently evaluated alongside other validated measures. Depending on the patient's presentation and specific diagnostic requirements, you may also need to utilize the CHA2DS2-VASc, CHADS2, Abcd3 I Score, Wells Pe Score, Heart Risk Score or the Ottawa Heart Failure Risk to formulate a comprehensive care plan.
