title: Is uncertain diagnosis a more frequent reason for referring migraine patients to neurologist than other headache syndromes?
abstract: The objective was to assess whether the physician's uncertainty of diagnosis was a more frequent motivation for referring migraine patients than other headache patients to a neurologist. In this population based survey we included 846 consecutive patients referred to and examined at a specialist centre for headache during a period of 2 years. As primary outcome we compared cross-sectionally frequency of referring patients with migraine and other headaches to neurologist. According to the patients, uncertainty of diagnosis was the main reason for referral to a neurological specialist consultation, i.e. in 51% of cases. Thirty-nine per cent of patients classified as having migraine were referred because of an uncertain diagnosis, compared with 62% in patient with other headaches (95 CI 0.13-0.33), (P < 0.0001). Headache subtypes other than migraine and younger age were associated to more uncertainty of diagnosis. We conclude that diagnostic uncertainty was an important factor amongst half the headache patients seen by neurologists and uncertain diagnoses as reason for referral was more important amongst patients with non-migrainous headache.
