How are transient ischemic attacks diagnosed?
Patients who experience a TIA should be seen by medical providers immediately. Evaluation includes examination by a doctor and diagnostic testing. The doctor will do some simple quick checks to test your vision, muscle strength, and ability to think and speak. Diagnostic testing consists of either a computed tomogram (CT) or magnetic resonance imaging (MRI) scan of the brain and carotid arteries to determine the possible cause of the TIA. Other tests include an electrocardiogram (ECG) of the heart, heart rate, body temperature, sleep study (to look for sleep apnea) and blood work (to look for risk factors for stroke – see above -- that can be treated).
