ABCD3-I vs ABCD2

Ovbiagele Bruce, MD, MS Published in Journal Watch Neurology December 7, 2010
Comment: "The ABCD3-I score is convincingly better than the ABCD2 score in predicting early stroke risk after TIA in real-world populations. Along with clinical characteristics, imaging information should be readily incorporated into decisions about the timing, nature, and extent of TIA management. However, further study is needed. First, a comparison of the ABCD3-I score with another recently proposed score (ABCD2-I) that adds only brain imaging (acute infarction) to the ABCD2 score would be helpful; The ABCD2-I score also improves stroke-risk prediction after TIA. Second, because routine imaging practice patterns after TIA vary from brain computed tomography only to detailed (brain, intracranial, and extracranial vasculature) MRI, establishing whether more-extensive imaging necessarily discriminates risk better and improves outcomes would be useful.
The ABCD3 score (range, 0–9 points) incorporates ABCD2 score variables (0–7 points) with information on prior TIA within 1 week of the index event (0–2 points); the ABCD3-I score (range, 0–13 points) incorporates the same information plus presence or absence of ≥50% carotid stenosis (0–2 points) and abnormalities on acute diffusion-weighted imaging (DWI; 0–2 points)"
