Rapid diagnosis of transient ischemic attacks (TIAs) and initiation of treatment appear to greatly reduce recurrent stroke risk in affected patients.
An estimated 10% or more of patients with a TIA will have a recurrent stroke within the following 90 days, with the greatest risk during the first 48 hours after onset of these minor strokes. Neurologists have presumed, based on experience, that rapid evaluation and treatment of a TIA improves outcomes, and research findings are now adding scientific rigor to anecdotal impressions.
