This study aims to evaluate the superiority of a clinical score (Canadian TIA score) compared to the currently more widely used score in clinical practice (ABCD2 score) in stratifying the risk of stroke or carotid revascularization following a transient ischemic attack at 7 days, and to assess its superiority at 90 days in a European population. Patients with transient ischemic attack are at high risk of developing a subsequent stroke, especially in the short term. Identifying patients at greater risk would allow for optimized management to provide aggressive treatment within the first days following the event. All patients attending the Emergency Medicine department of this hospital will be enrolled over a consecutive 24-month period. Approximately 800 participants are expected to take part in this study. At the time of admission to the Emergency Medicine department, the various prognostic scores relevant to the study will be completed, taking about one minute. At 7 and 90 days from the date of admission, the patient will be contacted by phone and will be administered a validated questionnaire (Questionnaire for Verifying Stroke-Free Status), which will take approximately one minute.
