Careful evaluation of headache is important to detect potentially morbid but treatable causes. Although such causes represent only 10% of all emergency department visits for headache, the consequences of a missed diagnosis can be severe. Unfortunately, the cost of performing computed tomography or magnetic resonance imaging for every patient with headache is prohibitive. However, familiarity with the differential diagnostic considerations, together with a high index of suspicion, should allow physicians to perform efficient, cost-effective examinations of all patients who seek treatment for headache.
仔细评估头痛对于发现潜在的严重但可治疗的病因很重要。尽管这些病因仅占所有因头痛前往急诊科就诊患者的10%，但漏诊的后果可能很严重。不幸的是，对每位头痛患者都进行计算机断层扫描或磁共振成像的成本过高。然而，熟悉鉴别诊断要点并保持高度怀疑指数，应能使医生对所有因头痛寻求治疗的患者进行高效且具成本效益的检查。
