The updated definition of TIA emphasizes tissue characteristics rather than symptom duration, defining as a transient neurological episode without ischemic lesions on brain imaging, including DWI. If imaging reveals lesion, even in patients with symptoms, the event is reclassified minor stroke. This retrospective cross-sectional study aimed to determine period prevalence DWI diagnosis. Adults aged 18–90 years, diagnosed by neurologist, and who underwent MRI-DWI at CMT hospital within first week after onset (May 2023–July 2024) were included. Ethical approval was obtained. Descriptive statistics summarized patient demographics, clinical features, Fazekas scale grades, findings. Among 26 clinically TIA, 7 (26.9%) exhibited DWI, reclassifying these cases strokes under definition. notably higher comorbidities such hypertension diabetes. findings highlight importance early accurately distinguishing TIAs from strokes. Routine urgent symptoms enhances diagnosis, risk stratification, guides targeted stroke prevention strategies, particularly when combined ABCD2 score.
