Headache is a universal problem, with a lifetime prevalence of 99%, and it is the most common reason for neurologic referral. Headache may be of little clinical significance or it may represent the onset of a life-threatening illness. To the patient, the symptom is always of major concern, and the relationship you establish with the patient at the initial visit will determine the success of treatment.
