I received an email via our iPhone App inquiring about migraines in children. Headaches are a common complaint throughout childhood, but pediatricians have recognized that children have many different types of headaches which include migraine headaches.
Migraine headaches are best diagnosed by obtaining a detailed history and then a thorough neurological exam. There are several characteristics of childhood migraines that are quite different than adult migraines. While adult females have a higher incidence of migraine headaches, males predominate in the childhood population.
Childhood migraines often are shorter in duration than an adult migraine and are less often unilateral (one sided) than in adults. Only 25-60% of children will describe a unilateral headache while 75-90% of adults have unilateral pain. Children do not typically have visual auras like adults, but may have a behavioral change with irritability, pallor, malaise or loss of appetite proceeding the headache. About 18% of children describe migraine with an aura and another 13% may have migraines with and without auras at different times. When taking a history it is also important to ask about family history of migraines as migraine headaches seem to "run in families".
Children who develop migraines were also often noted to be "fussy" infants, and they also have an increased incidence of sleep disorders including night terrors and nightmares. Many parents and children also report a history of motion sickness. When children discuss their headaches they will often complain of feeling dizzy (but actually sounds more like being light headed than vertigo on further questioning).
They may also complain of associated blurred vision, abdominal pain, nausea and vomiting, chills, sweating or even feeling feverish. A child with a migraine appears ill, uncomfortable and pale and will often have dark circles around their eyes. It seems that migraine headaches in childhood may be precipitated by hunger, lack of sleep as wells as stress. But stress for a child may be positive like being excited as well as typical negative stressors.
Children will also tell you that their headaches are aggravated by physical activity (including going up and down stairs, carrying their backpack, or even just bending over). They also complain of photophobia (light sensitivity) and phonophobia (sensitive to noises) and typically a parent will report that their child goes to bed in a dark room or goes to sleep when experiencing these symptoms.
Children with migraines do not watch TV or play video games during their headaches. They are quiet, and may not want to eat, and may just want to rest. Nothing active typically "sounds" like fun. To meet the diagnostic criteria for childhood migraine, a child needs to have at least 5 of these "attacks" and a headache log is helpful as these headaches may occur randomly and it is difficult to remember what the headache was like or how long it lasted, without keeping a log.
There are many new drugs that are available for treating child hood migraines and we will discuss that in another daily dose. Stay tuned!
