O011. Patients with 'prolonged aura' do not show clinical or demographic differences from the patients with 'typical aura'

Here we investigated in a prospective diary-aided study whether patients with a “prolonged aura” (PA an aura in which there is at least one symptom lasting for more than one hour) are different from the patients with a “typical aura” (TA).
