Clinical Overview

The ABCD2 score is designed to predict the risk of an impending stroke within the first few days following a Transient Ischemic Attack (TIA). By scoring Age, Blood pressure, Clinical features, Duration of symptoms, and Diabetes, it helps clinicians identify high-risk TIA patients who require urgent hospitalization and aggressive secondary prevention.

Clinical Pearl

While the ABCD2 score is a classic tool, modern stroke neurology heavily emphasizes urgent neuroimaging (MRI with DWI) and vessel imaging. Even with a low ABCD2 score, a patient with a critical carotid stenosis or restricted diffusion on MRI is at extremely high risk.

Pitfalls & Warnings

  • Fails to account for the exact etiology of the TIA (e.g., atrial fibrillation vs. carotid atheroma).
  • Has been largely supplanted in some academic centers by the ABCD3-I score, which incorporates imaging findings.
