Y1 - 2019 N1 - T2 - Pediatric Infectious Diseases: Essentials for Practice, 2e AB - Headache is defined as pain located at any part of the head, but not necessarily in a specific nerve distribution. Headaches can be primary or secondary. Primary headaches cannot be attributed to another medical, systemic, or intracranial disorder. A common primary headache is migraine. The criteria for pediatric migraine include at least five attacks lasting between 1 and 72 hours, at least one associated symptom (photophobia, phonophobia, vomiting, nausea), and at least two of the following major criteria: unilateral or bilateral location (i.e., bifrontal or bitemporal as opposed to global); pulsating or throbbing quality; moderate to severe intensity; and worsened headache on physical activity.1 Secondary headaches are caused by intracranial or medical/systemic disorders.2 For example, a child with a brain tumor and a headache has a secondary headache. When fever and headache occur simultaneously, the headache is almost universally a secondary headache.
