Migraine is a variant of headache often associated with neurologic and/or vegetative symptoms mainly represented by abdominal pain. This symptom may occur some hours before migraine manifestation and in these cases the differential diagnosis with other clinical conditions characterized by abdominal pain, which is very common during childhood, may be difficult. Abdominal migraine can be diagnosed only if a close relationship is demonstrated between the abdominal symptoms and migraine. Alteration of consciousness is a well known feature during migraine and in some cases EEG may show SNC involvement during the attack. We report a case of abdominal migraine attack evaluated by EEG. The patient, a 10 years old male, presented with a picture of acute abdomen. An EEG performed at the occurrence of the early headache symptoms and of consciousness alteration demonstrated a pattern characterized by a lowering in the electric activity on the left hemisphere. Some hours later he developed a clear migraine followed by disappearance of the abdominal symptoms. This observation confirms the possible association of migraine with a picture simulating an acute abdomen and suggests that the differential diagnosis with a true surgical condition may be achieved by the observation of the progression of symptoms and by early evaluation of patient with EEG.

The incidence of the life time history of both maternal migraine and depression were assessed in children with headache, migraine, recurrent abdominal pain and abdominal migraine. An epidemiological survey of 1,104 children registered with a general practice was undertaken. The incidence of maternal migraine and depression agreed with previous estimates. Children with migraine had a greater proportion of mothers with a history of migraine than those who experienced headache alone compared with controls. The survey showed that mothers with depression predisposed their children to headache but not specifically migraine. A history of maternal depression and migraine was significantly more common and proportionately higher in children with abdominal migraine and recurrent abdominal pain.

Abdominal migraine is well recognised in children, but in spite of anecdotal reports migraine is not well established as a cause of abdominal pain in adults. Functional abdominal pain is usually classified as either irritable bowel syndrome or nonulcer dyspepsia, but some patients have intermittent abdominal pain associated with headache or other migraine accompaniments and, in these, a diagnosis of abdominal migraine should be considered. It is possible that some patients with functional abdominal pain have migraine presenting with few or even no migraine accompaniments. There is no nonclinical objective standard for diagnosing migraine, and research in this area is therefore very difficult. Nevertheless, some patients with functional abdominal pain may respond to antimigraine medication and, if their symptoms are suggestive, a trial of therapy may be desirable.

Abdominal migraine is a common childhood migraine equivalent, for which diagnostic criteria have not been defined. As in other children with migraine equivalents this leads to difficulties in diagnosis and determination of prevalence. By recording the fast wave activity (beta rhythmn) in the visual evoked response (VER) to red and white flash, the pattern stimulation, 27 out of 28 children with clinically diagnosed abdominal migraine revealed significant differences compared with normal controls, outside the attack phase. Comparisons with children diagnosed as migraine with or without aura revealed, from the VER findings of higher amplitude fast wave activity and the presence of paroxysmal sharp wave activity, that abdominal migraine appears to be a specific form of childhood migraine. We found that both clinically and electrophysiologically, abdominal migraine changes with age; older children exhibiting a shorter duration of abdominal pain during attacks, and less evidence of sharp wave activity in the VER.

It has long been recognized that some cases of recurrent abdominal pain in children are related to migraine, but the diagnostic criteria for abdominal migraine have not been defined. We have identified a group of children with recurrent abdominal pain who had a family history of migraine--in over half the cases in a first-degree relative--and who obtained marked relief from their symptoms from specific anti-migraine therapy. These children had a well-defined syndrome comprising episodes of midline abdominal pain of sufficient severity to interfere with normal activities and lasting for prolonged periods, frequently accompanied by pallor, headache, anorexia, nausea, and vomiting. It is proposed that these children have "abdominal migraine".

The prevalence and clinical features of migraine headache and abdominal migraine were studied in the well defined population of Aberdeen schoolchildren. Ten per cent of all children (2165) aged 5-15 years were given a questionnaire inquiring, among other symptoms, about the history of headache and abdominal pain over the past year. A total of 1754 children (81%) responded. Children with at least two episodes of severe headache and/or sever abdominal pain, attributed by the parents either to unknown causes or to migraine, were invited to attend for clinical interview and examination. After interview, 159 children fulfilled the International Headache Society's criteria for the diagnosis of migraine and 58 children had abdominal migraine giving estimated prevalence rates of 10.6% and 4.1% respectively. Children with abdominal migraine had demographic and social characteristics similar to those of children with migraine. They also had similar patterns of associated recurrent painful conditions, trigger and relieving factors, and associated symptoms during attacks. The similarities between the two conditions are so close as to suggest that they have a common pathogenesis.

Recurrent abdominal pain in children, frequently diagnosed as "abdominal migraine," is thought to evolve into more typical migraine headache during the teens and twenties. If this transformation occurred, we would expect some adult migraineurs to retain abdominal pain; but we could not recall this symptom being mentioned by patients. However, without direct questioning the absence cannot be assumed. We, therefore, asked 100 migraineurs about abdominal symptoms during migraine attacks: only one experienced unexplained abdominal pain. We conclude that abdominal pain is not a feature in adult migraineurs, leading us to support the notions that: (1) recurrent abdominal pain of childhood has a number of causes; (2) abdominal migraine may be an incorrect attribution and is liable to be over diagnosed; (3) abdominal migraine requires more precise definition; (4) the transition from childhood abdominal migraine to adult migraine needs precise prospective study.

The present study examined the epidemiology of abdominal migraine among 1104 children registered with a general practice. There was a similar prevalence of recurrent abdominal pain as in other studies (8.4 per cent). The prevalence of headache was higher among children with recurrent abdominal pain and significantly so among girls. Migrainous headache was not significantly more prevalent in children with recurrent abdominal pain. The prevalence of abdominal migraine with and without migrainous headache was 0.7 and 1.7 per cent, respectively. The peak prevalence of abdominal migraine without migrainous headache was between five and seven years for both sexes. When associated with migrainous headache, it peaked at five to seven years in girls and seven to nine years in boys. The syndrome was associated with travel sickness and was more common among girls and those with a maternal history of migraine. Many children were photo- and phonophobic during an attack.

Migraine according to the criteria of the International Headache Society, occurs in about 3 to 7% of all children. Despite this high incidence, and unlike the situation with adult migraine, only a very few controlled trials have investigated the acute and prophylactic treatment of migraine in children. In the acute migraine attack, ibuprofen 10 mg/kg and paracetamol (acetaminophen) 15 mg/kg have been shown to be effective, with only a few adverse effects. In severe migraine attacks, dihydroergotamine mesylate (dihydroergotamine) administered orally (20 to 40 microg/kg) or intravenously (maximum 1 mg/day) may be helpful, but there have been no large placebo-controlled trials of this treatment. Oral sumatriptan has not been effective in several double-blind and placebo-controlled trials; administered subcutaneously, this drug might be helpful but the only data for this application come from open trials. For migraine prophylaxis, only flunarizine 5 mg/day has been shown to be effective in more than 1 double-blind, placebo-controlled trial. Some evidence also exists that propranolol >60 mg/day and pizotifen 0.5 to 1.5 mg/day are effective; however, the results from different trials are contradictory. For all other drugs studied in migraine prophylaxis, the results remain vague (e.g. amitriptyline, nimodipine, trazodone) or suggest inefficacy (e.g. timolol, clonidine, tryptophan). In migraine-related disorders, pizotifen 0.5 to 0.75 mg/day for abdominal migraine and flunarizine 10 to 25 mg/day for alternating hemiplegia have been shown to be effective. Most of the drugs used in the treatment of migraine in children are well tolerated and without relevant adverse effects. In migraine prophylaxis, the most common adverse effects are drowsiness and bodyweight gain.

There is evidence to suggest that, in children, episodic abdominal pain occurring in the absence of headache may be a migrainous phenomenon. There are four separate strands of evidence for this: the common co-existence of abdominal pain and migraine headaches; the similarity between children with episodic abdominal pain and children with migraine headaches, with respect to social and demographic factors, precipitating and relieving factors, and accompanying gastrointestinal, neurological and vasomotor features; the effectiveness of nonanalgesic migraine therapy (such as pizotifen, propanolol, cyproheptadine and the triptans) in abdominal migraine; and the finding of similar neurophysiological features in both migraine headache and abdominal migraine. Abdominal migraine is rare, but not unknown, in adults. Many families are content with a diagnosis and reassurance that the episodes, though distressing, are not the result of serious pathology. Some patients respond to simple dietary and other prophylactic measures. There is scant evidence on which to base recommendations for the drug management of abdominal migraine. What little literature exists suggests that the antimigraine drugs pizotifen, propanolol and cyproheptadine are effective prophylactics. Nasal sumatriptan (although not licensed for pediatric use) may be effective in relieving abdominal migraine attacks.
