Headache represents the second neurological cause of emergency room admittance. The differentiation of the small number of patients with life-threatening headaches from the overwhelming majority with benign primary headaches is an important problem in the emergency department since the misdiagnosis of a secondary headache can have serious consequences, including permanent neurologic deficits and death. The presence of one or more high-risk features (red flags) in patient clinical history or neurological examination warrants an urgent diagnostic workup including blood tests, neuroradiological studies, and lumbar puncture.
