Migraine History: A Predictor of Negative Diffusion-Weighted Imaging in IV-tPA-Treated Stroke Mimics

Background: Migraine, seizures, and psychiatric disorders are frequently reported as “stroke mimics” in patients with negative diffusion-weighted imaging (DWI) after IV-tPA. We sought to determine predictors of negative DWI in suspected stroke patients treated with IV-tPA. Method: A retrospective case-control study encompassing all acute stroke patients treated with IV-tPA (at o ur hospital or “dripped and shipped”) from January 2013 to December 2014 was con- ducted. A total of 275 patients were identified with 47 negative DWI cases and 228 positive DWI controls.
