Early stroke risk after a TIA is stratified with the ABCD2 score: Age >60, BP, Clinical features, Duration of symptoms, Diabetes.

• Both age (B) and duration of symptoms (D) are ABCD2 items, so the stem as recalled has two defensible answers.
• Duration carries more weight (up to 2 points for >60 min vs 1 point for age), which is why D is the usual keyed answer.
• Gender and hyperlipidaemia are not part of the score.
