Migraine is a common cause of undiagnosed headache in children. Studies suggest that around 60% of children aged between 7 and 15 experience headache. Around 1-2% of 7-year-olds and 2.5% of 9-year-olds have migraine; more than 5% of 15-year-olds are affected1. Migraine affects boys and girls equally until puberty, after which migraine is more prevalent in girls2,3. Severe pain and vomiting mean that children often have to remain at home during attacks and are unable to participate in normal daily activities. If such attacks are frequent, migraine can have a significant detrimental effect on schooling3.

Diagnosing migraine

Migraine in children differs from migraine in adults in several ways:

ā  Headache typically affects the whole head, rather than one side

ā  Headache may be only a minor symptom and may be absent

ā  Vomiting and/or abdominal pain are prominent

ā  Attacks are shorter, sometimes lasting less than an hour

As in adults, children are pale and lethargic. There is no diagnostic test for migraine, so diagnosis depends entirely on the story and pattern of attacks. A headache diary is an invaluable aid both for diagnosis and management. Recurrent bouts of headache with nausea or vomiting, with complete freedom from symptoms between attacks in an otherwise healthy child, are probably migraine. Some children look pale and yawn for a few hours before the headache starts; others are bursting with extra energy. Some children may experience migraine aura, typically bright visual zig-zags or blind-spots, lasting up to an hour before the headache starts. Attacks may last only a couple of hours; parents and carers are often surprised at how quickly children recover.

When should I take my child to the doctor?

It may be obvious, particularly if you have migraine yourself, that your child’s symptoms are typical of migraine. If attacks have obvious causes, symptoms respond to painkillers, and your child is otherwise fit and well, it is probably not necessary to seek a doctor’s advice. However, you should make an appointment for your child to see a doctor if there is any doubt about the nature or cause of the headaches, if your child seems generally unwell, or if the headaches are interfering with daily activities.

In particular, it is very important to see a doctor in the following circumstances:

ā  Headaches start under age 7

ā  The headache changes

ā  An unaccountable increase in frequency, severity and duration of attacks

ā  Recent school failure

ā  Personality/behavioural changes

ā  Fits or blackouts

ā  Balance or co-ordination problems

ā  Failure to grow/attain normal developmental goals

When do I need to call the doctor urgently?

Increasingly frequent severe headache, particularly if associated with seizures, persistent vomiting, fever, and blacking out, are all symptoms requiring urgent medical attention.

Managing migraine

Migraine in children is essentially managed in the same way as migraine in adults but as children also spend a lot of time at school we have also included advice specific to schools in an Appendix.

The main concerns that need addressing are:

ā  What causes the headaches?

ā  What will make the headaches better?

The cause

Inadequate nutrition is probably the major trigger in this age group, particularly during the adolescent growth spurt. It is not uncommon for children to rush off to school after an inadequate breakfast, taking a packed- lunch that they do not eat because they would rather play games in the lunch hour. It is not surprising that many children develop a headache by late afternoon. Parents should make an effort to provide their children with an adequate breakfast so that, even if they do miss lunch, at least they have been set up for the day. Food allergy in children is contentious, currently trendy and not nearly as important as all the hype would suggest. A few susceptible children have a convincing relationship between the consumption of certain foods and the onset of migraine but keeping a food & migraine diary usually makes this clear. Do not continue restricting the child’s diet in the absence of a clear trigger: we meet children living on little more than rice and water because of unfounded fears about food allergies. More often a false trail occurs. For instance missed meals make a child more likely to crave sweets or chocolate (and the migraine is blamed on the chocolate, not the missed meal). Or the sweet cravings are actually one of the prodromal symptoms of migraine, in other words the migraine was on the way and the desire for chocolate was part of that: nevertheless the chocolate gets blamed as the migraine trigger. For the vast majority, it is unnecessary and actively unhelpful to restrict food and much more important to ensure that children have a sensible and regular “healthy eating” diet.

Adequate hydration is equally important: many children drink inadequately at school (sometimes from well-founded fears of using the school toilets!). Ensure children take a bottle of water to school, speak to the school to make sure it is allowed on their desks and check it comes home empty each afternoon. Whilst on the subject of drinks, avoid sugary drinks like coca-cola and Lucozade. These give a rapid increase in blood sugar levels followed by a sugar crash which often triggers an attack. The sugar free ones may not be much better: artificial sweeteners and other additives can act as triggers and many contain caffeine – another potential trigger.

Adequate and regular sleep is vital. Many kids stay up late and watch TV or use video games. Fix a regular bedtime which allows adequate sleep – up to 11 hours for school age children (see https://sleepfoundation.org/how-sleep-works/how-much-sleep-do-we-really-need). Having a “screen free” wind down time before bed (you can’t beat the old fashioned bedtime story) means the child gets to bed prepared for sleep. Inadequate sleep and erratic sleep patterns are powerful migraine triggers.

Bear in mind that flickering lights, fluorescent lighting in schools and exposure to computer and TV screens are important triggers for some.  Avoiding excessive screen time and having a desk by the window can all help.

Sport frequently triggers attacks, by causing dehydration, by lowering blood sugar and by the exertion itself. Drinking lots of water and having a snack before and after the match reduces the risk. Sucking glucose tablets during the game can help. Mid- morning and mid-afternoon snacks can be helpful for sport related problems and more generally. Unless there is absolutely no alternative, (and remember some drugs can help) don’t restrict children’s participation in sport: fit kids get fewer headaches than unfit ones. Another strategy may be to increase the amount of exercise through the rest of the week so that the child is generally fitter rather than having just one “big bang” sports session.

Migraine in girls may coincide with puberty and the start of menstruation.

Keep diaries

Just as in adults, migraine is often set by a combination of triggers events, not just a single event. Encourage your child, if old enough, to keep a daily trigger diary recording any event that is different from the normal routine, or which may be relevant. This can include missed meals, sports activities, stressful lessons, late night study, emotional upsets, etc. A record of migraine attacks and other headaches should be kept separate from this. After a few months, you can look through the diaries together with your child, noting patterns of any build-up of triggers, or specific triggers, preceding attacks. Having identified possible culprits, their relevance can be assessed by avoiding them, one at a time, over subsequent months.

It is impossible to avoid all triggers but it is also unnecessary to do so. Triggers build up and only provoke an attack when they reach the migraine threshold – the “tipping point”. By avoiding the triggers this will then hopefully mean the remaining ones will not be enough to reach the attack threshold (although it is not realistic to imagine one can avoid all attacks). Children can also learn which situations are more likely to provoke attacks enabling them to treat attacks early.

Making the headache better

Drugs to control the symptoms

Resting in a quiet, darkened room, using a hot or cold pack to ease the pain, and gentle massage, may be sufficient to control mild symptoms. Most children want to lie down during an attack and they should be encouraged to sleep as this can hasten recovery. Encourage your child to eat or drink something, if possible.

Drug treatment should be kept simple. If taken early in an attack, over-the-counter analgesia may be all that is necessary. Use syrups, soluble or effervescent painkillers as they are absorbed more easily than tablets. Taking them with a sweet drink not only makes them more palatable but gives a hit of sugar and helps absorption, both of which help. Give the maximum safe dose of the painkiller as early in an attack as possible. It is much better and more effective to give a single high dose early, rather than several small ones – go for the “knock-out blow”. One of the problems with migraine is that the gut shuts down during the attack, which can delay absorption of drugs, reducing their effectiveness.

It is worth discussing this with the school and providing staff with specific written instructions for management, stressing the need for early treatment. Some schools will only give drugs if they are prescribed by a doctor. Although it may seem daft having to go to your GP for everyday paracetamol or ibuprofen, this may be necessary to keep the school on side.

Schools have different rules regarding treatment. In some schools, teachers and/or nurses may agree to administer some medication. Ibuprofen is usually the most effective painkiller in migraine and syrup is readily available. Paracetamol is a good second best which is also available as a suppository – potentially useful if children are vomiting. Migraleve is an over-the-counter tablet for children over age 10, combining paracetamol, codeine and buclizine, which can help nausea (although codeine by itself is not good in migraine). Aspirin is not recommended for children under 16. Children should avoid drugs containing caffeine.

If these are inadequate to control symptoms, other drugs are available on prescription from your doctor. Some studies have demonstrated the efficacy of triptans in children, but most are still not recommended for patients under the age of 18 years. An exception is sumatriptan nasal spray, which can be given to adolescents over age 12.

Preventing migraine

Identification and management of trigger factors are the mainstay of treatment. Children also respond well to biofeedback and relaxation techniques, which should be considered before instigating drug therapy. Unless the headaches are really disabling, it is rarely necessary to give children daily drugs to prevent attacks. A short course of preventative drugs may be indicated when there is concern that attacks are interfering with normal school work – often around exam time. The child should try them out before the critical time to ensure that the drug can be tolerated and side- effects do not compromise performance. The most commonly prescribed prophylactics for children are propranolol and pizotifen, with pizotifen being the drug of choice. Cyproheptadine may also be used. These are available on prescription.

When treatment fails

If children are experiencing frequent attacks of migraine or headache, particularly if these are not responding to simple management strategies, there may be other underlying problems such as depression, bullying at school, or other emotional problems. Overuse of acute medication should be considered as this can itself be a cause of frequent headache. Drugs to treat the symptoms of migraine should not be used regularly on more than two to three days a week.

Case study: Mary

Mary is 12 and has had migraine since she was nine. Attacks used to be infrequent but for the last couple of months she has been having attacks most weeks, often starting late afternoon when she gets home from school. She gets really bad stomach pains, looks pale, and goes straight to bed. A couple of hours into the attack, she vomits and then feels much better. By the next morning, she is fine. Her mother is concerned that these attacks are affecting her schoolwork, as her homework doesn’t get finished when she is ill. Her mother takes her to the doctor, who asks if Mary has needed new shoes or outgrown her clothes recently. Her mother replies that she has been growing rapidly over the last few months and her periods started last year. The doctor explains that growth spurts are common time for migraine to worsen. The doctor asks Mary what she eats for lunch and which sports she enjoys. Mary replies that she takes a packed lunch but doesn’t always eat it. Her mother answers that Mary often wakes up too late for a decent breakfast and comments that the migraines are often after Mary has had a swimming lesson. The doctor recommends that Mary tries to eat more sensibly, particularly on swimming days, making time for a more substantial breakfast and with a snack to eat as soon as she comes home from school. Mary and her mother return a few weeks later to report that his simple advice has been very effective. Mary also comments that she has much more energy after school.

Summary points

ā  Migraine can occur in children and adolescents and is more common that many people realise

ā  Recurrent attacks of ‘sick’ headaches or bilious attacks in an otherwise well child is likely to be migraine

ā  Headache may not be a feature of migraine in children; abdominal pain is often more prominent
