ABCD² Score

Early stroke risk after TIA.

Education and reference only. Not a substitute for clinical judgement, local policy or product labelling. Always verify before clinical use. Values are calculated in your browser and never stored.

When to use

Use after a suspected TIA to estimate short-term stroke risk. Note many pathways now urgently assess all TIAs regardless of score.

Why use

It highlights higher-risk patients, though current UK guidance favours rapid specialist assessment for all.

Advice

UK guidance (NICE) recommends urgent specialist assessment for everyone with a suspected TIA, irrespective of ABCD² score.
