The ABCD and ABCD2 Scores and the Risk of Stroke following a TIA: A Narrative Review

The California, ABCD, and ABCD2 risk scores (ABCD system) were developed to help stratify short-term stroke risk in patients with TIA (transient ischemic attack). Beyond this scope, the ABCD system has been extensively used to study other prognostic information such as DWI (diffusion-weighted imaging) abnormalities, large artery stenosis, atrial fibrillation and its diagnostic accuracy in TIA p...

The California, ABCD, and unified ABCD2 risk scores and the presence of acute ischemic lesions on diffusion-weighted imaging in TIA patients.

BACKGROUND AND PURPOSE Some clinical models, like California ABCD and unified ABCD2 scores, are now available to predict the early risk of stroke after a TIA. Despite the transitivity of symptoms, DWI identified an area of acute brain ischemia in almost half of patients. It would be interesting to know how the presence of DWI abnormalities relates to clinical risk scores to plan other prognosti...

Prediction of early stroke recurrence in transient ischemic attack patients from the PROMAPA study: a comparison of prognostic risk scores.

BACKGROUND Several clinical scales have been developed for predicting stroke recurrence. These clinical scores could be extremely useful to guide triage decisions. Our goal was to compare the very early predictive accuracy of the most relevant clinical scores [age, blood pressure, clinical features and duration of symptoms (ABCD) score, ABCD and diabetes (ABCD2) score, ABCD and brain infarction...

Validation and refinement of scores to predict very early stroke risk after transient ischaemic attack.

BACKGROUND We aimed to validate two similar existing prognostic scores for early risk of stroke after transient ischaemic attack (TIA) and to derive and validate a unified score optimised for prediction of 2-day stroke risk to inform emergency management. METHODS The California and ABCD scores were validated in four independent groups of patients (n=2893) diagnosed with TIA in emergency depar...
