Headache as an emergency in children and adolescents.

Pediatric and adolescence headache is one of the most common causes of access in emergency departments (ED). Primary headache and headache secondary to self-limited conditions are the majority of cases. Secondary life-threatening headaches are less frequent and may be recognized by a careful history and physical examination. The primary objective for ED physicians is to recognize the serious life-threatening conditions requiring immediate medical care among the wide spectrum of headache diagnoses.
