On the basis of his presentation, this patient is probably experiencing migraine with visual aura. Migraine is a condition in children and adolescents whose prevalence increases with age: 1%-3% between age 3 and 7 years, 4%-11% between age 7 and 11 years, and 8%-23% by age 15 years. Although migraine without aura is relatively uncommon in the pediatric population, visual aura is a hallmark sign of migraine headache and excludes the other headache types in the differential diagnosis. Basilar migraine is unlikely because the patient has not experienced symptoms that suggest occipital or brainstem area dysfunction post-aura.
The diagnosis of migraine is largely clinical, but the American Academy of Neurology (AAN) guidelines for the acute treatment of pediatric migraine recommend that when assessing children and adolescents with headache, clinicians should diagnose a specific headache type: primary, secondary, or other headache syndrome. Migraine in pediatric patients is often related to triggering factors such as infection, physical or psychological stress, or dietary choices, but on the basis of the patient's history, this headache appears to be primary in nature.
Most pediatric patients can achieve control of their migraines with acute treatments and benefit from nonprescription oral analgesics, including acetaminophen, ibuprofen, and naproxen. Clinicians should prescribe ibuprofen orally (10 mg/kg) as an initial treatment for children and adolescents with migraine. The US Food and Drug Administration has only approved certain triptans for pediatric patients: almotriptan, sumatriptan-naproxen, and zolmitriptan nasal spray for patients aged 12 years or older and rizatriptan for patients aged 6-17 years.
The AAN guidelines for the pharmacologic treatment of pediatric migraine prevention report that for those who experience migraine with aura, taking a triptan during the aura is safe, though it may be more effective when taken at the onset of head pain, as is the case with other acute treatments.
In pediatric patients, avoidance of known headache triggers is generally sufficient for migraine prevention. This includes managing anxiety, depression, attention-deficit/hyperactivity disorder, and other psychiatric comorbidities that can exacerbate headache. Lifestyle management also includes ensuring adequate sleep, exercise, hydration, and stress management.
The guidelines conclude that although the majority of randomized controlled trials exploring the efficacy of preventive medications in the pediatric population fail to demonstrate superiority to placebo, migraine prophylaxis should be considered when headaches occur with high frequency and severity and cause migraine-related disability based on the Pediatric Migraine Disability Assessment (PedMIDAS).
