When to Use

When to Use

All patients with suspected TIA to stratify 2-day and 7-day stroke risk

Guide urgency of neurovascular investigation and admission decisions

Determine speed of antiplatelet initiation and carotid imaging

Communication tool for referral urgency to neurology or stroke units

Important Caveat

ABCD2 score is a risk-communication tool, NOT a rule-out tool. A score of 0 does NOT exclude early stroke risk. ALL TIA patients require same-day or next-day evaluation regardless of score. NIHSS guidelines recommend TIA clinic within 24h for ALL patients.
