Description: The ABCD2 scoring system for assessing stroke risk after a TIA (transient ischemic attack); formatted as an Epic Smart Phrase.

Stroke risk after transient ischemic attack.

  • A. Age > 60 years = +1
  • B. Blood pressure > 140/90 mmHg: +1 for hypertension at presentation
  • C. Clinical features including unilateral weakness (+2), speech disturbance without weakness (+1)
  • D. Duration of TIA between10–59 minutes (+1), >60 minutes (+2).
  • D. Diabetes (+1).

Stroke risk at 2, 7 and 90 days

  • 0-3: low risk
  • 4-5: moderate risk
  • 6-7: high risk

Not that stroke risk is independent of mechanism whether cardioembolic, a watershed infarct, lacunar infarct, or other mechanism.
