چکیده

Introduction: One type of stroke is the Transient Ischemic Attack (TIA) which lasts less than twenty-four hours; of all patients, about ۱۰ percent develop a stroke within three months after the first symptoms, and ۳۰ percent develop over five years. Imaging is needed for differential diagnosis of this type of stroke. This study aimed to evaluate the recurrence of ischemic stroke and TIA three months after the first transient ischemic attack based on DWI results.Materials and Methods: This cross-sectional study was done on ۱۳۵ TIA patients referred to Alavi Hospital in Ardabil City. All patients were examined at admission time by DWI imaging and laboratory tests and followed up three months later by phone and hospitalization, and necessary information was collected by a checklist.Results: The average ABCD۲ score in people with and without recurrence was ۴.۶۹ and ۴.۰۲, respectively. Also, the mean ABCD۲ score in individuals with abnormal DWI was significantly higher than in individuals with normal DWI (۴.۷۲ vs. ۴.۰۴, p=۰.۰۰۱). After the first TIA attack, patients with abnormal DWIs had a significantly higher recurrence of TIA and stroke in the first ۹۰ days. Conclusion: This study showed that TIA patients with higher ABCD۲ scores in the first ۲۴ hours based on DWI are more likely to have a recurrence of TIA or the onset of stroke within ۹۰ days.
