Today we reviewed the approach to a patient presenting with symptoms suggestive of a Transient Ischemic Attack (TIA).
A TIA is defined as an abrupt focal loss of neurologic function caused by reduction in blood flow that persists less than 24 hours and clears without residual disability.
• Acute persistent or fluctuating stroke symptoms
• One positive investigation (evidence of acute infarct on CT/MRI; evidence of carotid artery stenosis > 50%)
• Other factors based on individual presentation and clinical judgment
