Pediatric primary headache is one of the leading health care issues in high-income countries that is rising in prevalence. 1 Frequent headaches are strongly associated with a lower quality of life and poorer academic performance and are a leading cause of school absence. 2 The classification system of the International Headache Society provides a navigation system to phenomenologically diagnose migraines, tension-type headaches, and other primary headaches (http://www.ihs-classification.org/_downloads/mixed/ International-Headache-Classification-III-ICHD-III-2013-Beta. pdf); however, pediatric-specific factors have not been considered sufficiently. 3 A migraine is not just a headache-it is a complex neurological condition. More than 60% of children with migraine display a premonitory phase before the migraine attack. It is characterized by various symptoms, such as pallor or shadows under the eyes, fatigue, irritability, anxiety, phonophobia, yawning, photophobia, nausea, and, less commonly, concentration problems, food craving, cacosmia, hyperactivity, stiff neck, neck pain, sadness, and sleep problems. 4 More than 50% of children with migraine show cranial autonomic symptoms, such as a red ear, facial flushing, conjunctival injection, lacrimation, nasal obstruction, facial sweating, ptosis, yawning, rhinorrhea, eyelid edema, or miosis. The cranial symptoms are bilateral in 70% of cases. 5 A migraine attack may also be accompanied by other autonomic symptoms (nausea, vomiting, frequent urination, and diarrhea), affective symptoms (depression and irritability), cognitive symptoms (eg, attention deficit, difficulty finding words, or transient amnesia), and sensory symptoms (photophobia, phonophobia, osmophobia, and cutaneous allodynia). 6 Patients with migraine, especially those with migraine with aura, more often experience various transient sensory and neuropsychological symptoms like visual illusions (eg, autokinesis, corona phenomenon, cinematographic vision, double vision, metamorphopsia, visual splitting, dyschromatopsia, and illusionary visual spread) or complex higher cortical dysfunctions (altered perception of body size, weight, or position in space). 7 Therefore, a useful rule for pediatricians and pediatric neurologists is to believe a child with a migraine who tells you strange stories.Some key differences between children and adults in migraine presentation are evident. For example, during the migraine attack, children often show bifrontal or bitemporal pain instead of the clear pain laterization reported in adults. Additionally, the migraine attack duration in children can be shorter than in adults, for whom it typically lasts many hours. 3 Fur-
