Our study adopts a prospective design. Our research aims to determine the significance of ABCD2, ABCD3-I, Canadian TIA Score, and NIHSS Score in predicting the likelihood of ischemic stroke within 30 days in patients presenting to the emergency department with transient ischemic attack (TIA)

Our study is planned as follows: Patients diagnosed with transient ischemic attack (TIA) presenting to the emergency department will undergo scoring by researchers, although they will not intervene the treatment process of the patients. Patients will be contacted by researchers or their families to ascertain whether they experience a recurrent stroke or TIA within 30 days, and their current health status will be assessed. The collected information will be recorded.

The study will include patients diagnosed with transient ischemic attack (TIA) based on tests and imaging conducted at Ankara Etlik City Hospital's emergency department. The planned duration for data collection and analysis is one year.

Parameters to be examined:

Age Gender Physical examination findings Comorbidities (hypertension, coronary artery disease, valvular heart disease, COPD, asthma, diabetes, others) Neurological examination findings Time of symptom onset Admission status (intensive care unit / ward) Findings from ultrasound, computed tomography, and MRI imaging Length of hospital stay Mortality (yes/no)

We aim to collect data from approximately 300 patients within the course of one year for our study

Inclusion Criteria:

Patients presenting to the emergency department and diagnosed with TIA Patients diagnosed with ischemic stroke who did not receive thrombolytic therapy based on NIHSS score Patients aged 18 and above Patients who consented by signing the informed consent form

Exclusion Criteria:

Patients diagnosed with hemorrhagic stroke Patients unwilling to participate in the study Patients with a history of trauma Patients unable to receive thrombolytic therapy for any reason (trauma, malignancy, etc.) Patients under the age of 18 Patients transferred from another hospital Patients who experienced cardiac arrest Patients who died for any reason other than ischemic stroke within 30 days Patients wishing to withdraw from the study at any time during the study period

patients over the age of 18 presenting to emergency department with symptoms of stroke and diagnosed with TIA will be enrolled to study and will be followed up for 30 days for recurrent TIA or stroke
