Treatment of TIA with Low ABCD2 Score (<4) or Uncertain Diagnosis
Clinical Scenario
Acute non-cardioembolic transient ischaemic attack with an ABCD2 score below 4 (low risk), or a presentation in which the TIA diagnosis remains uncertain.
Antiplatelet Approach
Antiplatelet monotherapy is the recommended strategy for this presentation — the conditions under which initiation timing relative to planned imaging matters are addressed in the full protocol.

- For patients with acute non-cardioembolic low risk TIA or uncertain TIA diagnosis, 9/9 experts voted against using dual antiplatelet therapy over monotherapy.
- In patients suspected of TIA, if a wait of more than 24 hours to planned imaging is foreseen and a delay is judged to increase the risk of further ischaemic events, above the risk of starting antiplatelet medication, we suggest “de novo” antiplatelet monotherapy usage compared to not starting antiplatelet monotherapy.
