Headache is the fourth most common reason for emergency department encounters, accounting for 3% of all visits in the United States. Though troublesome, 90% are relatively benign primary headaches --migraine, tension, and cluster headaches. The other 10% are secondary headaches, caused by separate underlying processes, with vascular, infectious, or traumatic etiologies, and they are potentially life-threatening. This issue details the important pathophysiologic features of the most common types of life-threatening headaches, the key historical and physical examination information emergency clinicians must obtain, the red flags that cannot be missed, and the current evidence for best-practice testing, imaging, treatment, and disposition.
Excerpt From This Issue
A previously healthy 30-year-old man presents to the ED complaining of the “worst headache of my life.” He describes it as sharp, nonradiating, with an abrupt onset 5 hours ago.

You wonder whether a negative CT is sufficient to rule out an SAH or whether a lumbar puncture should be done...
A 55-year-old man with history of nonsmall cell lung cancer who is on cisplatin presents with an acute headache and lethargy for 6 hours. His vital signs are remarkable for a blood pressure of 210/120 mm Hg, heart rate of 70 beats/min, and a temperature of 36.7°C (98°F). His physical exam reveals a lethargic patient with no localizing neurologic signs and no meningismus. You order a noncontrast CT of the head and consider lowering this patient’s blood pressure, though you wonder how much and how fast it should be reduced...
