The short-term risk for stroke after transient ischemic attack (TIA) is high, and urgent evaluation and treatment can reduce this risk. However, since TIA can present with a broad range of neurologic symptoms, when symptoms could be consistent with but are not classic for TIA, the possibility that symptoms could be nonvascular is increased, calling into question the TIA diagnosis, estimates of subsequent stroke risk, and optimal management. Now, researchers report the prognosis of a large population-based cohort of patients who sought medical attention for sudden-onset transient neurologic symptoms as part of the Oxford Vascular Study. Patients were prospectively classified as having minor stroke (n=1287), classic TIA (n=1021; motor weaknes…
