Prevalence and Diagnosis of Migraine in Patients Consulting Their Physician With a Complaint of Headache: Data From the Landmark Study

Abstract

These findings support the diagnostic approach of considering episodic, disabling primary headaches with an otherwise normal physical exam to be migraine in the absence of contradictory evidence. If in doubt of diagnosis or when assigning a nonmigraine diagnosis, strong consideration should be given to the use of a diary to confirm primary headache diagnosis.
