The ABCD2 system is a quick clinical score that can help predict early risk of stroke in the first two days after transient ischemic attack (TIA). The early stroke rates in acute TIA patients were reported by Johnston and colleagues based on combined analysis of 6 cohorts with a total of 4799 TIA patients who were evaluated within 48 hours of TIA. The diagnosis of TIA was made by the initial treating physician, and therefore the usefulness of the scale may be generalized beyond stroke specialists.
ABCD2 is scored as follows:
