Used to predict the risk of stroke during the first seven days after a TIA. Researchers found there to be over 30% risk of stroke in TIA patients with an 'ABCD score' of six, as compared to no strokes in those with a low ABCD score. Can be used in routine clinical practice to identify high-risk individuals who require emergency investigation and treatment.
