Transient ischemic attack (TIA) and stroke prediction scores have been a topic of both clinical and research interest for decades. The goal of these scores is to identify high-risk patients for both prognostic and clinical management purposes. There are several TIA and stroke prediction scores that aim to prognosticate recurrence or worsening of cerebrovascular events (CVEs). Some are purely clinical scales (eg, California, ABCD, ABCD2, and ABCD3), while others incorporate cerebral parenchyma and/or vascular imaging (eg, Clinical and Imaging-based Predictive model, Recurrence Risk Estimator at 90 Days, ABCDE+, ABCD-I, ABCD2-I, ABCD3-I, and ABCD3-V).
