Popis: The International Classification of Headache Disorders 2nd edition (ICHD-2) subdivides migraine with aura (MA) differently from the ICHD-1 and includes new diagnostic criteria. The aim of the present study was to evaluate how the new classification works in practice and in comparison with the ICHD-1. The patients were recruited from a screen of the Danish National Patient Registry and from Danish neurologists. We included 362 patients diagnosed with MA according to the ICHD-1 in a validated semistructured physician-conducted interview. According to the ICHD-2, 89% (322 of 362) had MA and 11% (40 of 362) had probable MA. The MA patients had one or more ICHD-2 subtype of MA: 54% (173 of 322) had typical aura with migraine headache (MA-MH), 40% (129 of 322) had typical aura with non-migraine headache (MA-NMH), 37% (120 of 322) had aura without headache (MA-WOH), and 7% (26 of 322) had basilar-type migraine (MA-B). Of patients with MA-MH 34% (59 of 173) had co-occurrence of MA-WOH, 9% (16 of 173) had co-occurrence of MA-B and 5% (8 of 173) had co-occurrence of both MA-WOH and MA-B. Of patients with MA-NMH 27% (35 of 129) had co-occurrence of MA-WOH. Only 6% (18 of 322) of the MA patients had exclusively MA-WOH and
