We investigated whether the criteria for idiopathic headache published by the International Headache Society (IHS) are useful in childhood and adolescence and compared the diagnoses according to this classification with those of Vahlquist. We used a semi-structured questionnaire to examine a total of 437 children and adolescents referred consecutively to a headache outpatient clinic. Twenty-eight of 437 patients were excluded because of symptomatic or unclassifiable headache. Of 409 patients with idiopathic headache, 70.4% had definite migraine or tension-type headache (IHS 1.1, 1.2, 2.1, 2.2), 20.5% had a migrainous disorder (IHS 1.7) and 9.1% had headache of the tension-type not fulfilling the criteria (IHS 2.3). In the differential diagnosis of migraine and tension-type headache the intensity of pain, aggravation of headache by physical activity, nausea and vomiting were the most important features. The quality of pain, photo- and phonophobia were less helpful and location least important. The duration of migraine attacks was less than 2 h in 19.0% of the migraine patients. In general, the diagnostic criteria of migraine were highly specific but less sensitive, and those of tension-type headache highly sensitive but less specific. The agreement between IHS criteria and those of Vahlquist was marked (kappa = 0.57). We conclude that the IHS criteria are useful for classifying headache in children and adolescents referred to a headache outpatient clinic. A forthcoming modification of the IHS criteria should consider a reduction of the minimum duration of migraine attacks from 2 h to 1 h and should try to increase the sensitivity of the criteria for migraine and the specificity of the criteria for tension-type headache.
We investigated the influence of age on the IHS criteria for migraine and tension-type headache in 437 consecutive children and adolescents and found the following age-associated statistically significant differences: migraine duration, occurrence of migraine aura, and bilateral location of tension-type headache were more often fulfilled by adolescents, whereas aggravation of headache by physical activity (in migrainous disorder) and photophobia (in migraine with aura) were more often fulfilled by children. Accordingly, there are only a few differences concerning the fulfillment of the IHS criteria for migraine and tension-type headache in children and adolescents. Independent of age, the intensity of headache and the presence or absence of nausea are most important for differentiating the two major types of idiopathic headache. The sensitivity of the IHS criteria for migraine could be increased by reducing the minimum duration of migraine and by allowing the diagnosis of migraine when severe headache is associated with nausea, even though the criteria of location, quality, and aggravation by physical activity are not fulfilled.
We investigated 341 children and adolescents to evaluate the relevance of psychosocial factors in idiopathic headache. According to the criteria of the International Headache Society, 151 subjects had migraine and 94 had tension-type headache (TTH). Ninety-six subjects were headache-free controls. Psychosocial factors covered family and housing conditions, school problems, relations in the peer group, and several other items. We found that migraine patients did not differ from headache-free controls. Patients with TTH more often had divorced parents than the headache-free controls, and they had fewer peer relations than migraineurs and controls. In addition, migraine patients were significantly more often absent from school due to headache. All other psychosocial factors failed to discriminate between the three study groups. In conclusion, this controlled study in children and adolescents suggests that migraine is not related to family and housing conditions, school situation, or peer relations, whereas TTH is associated with a higher rate of divorced parents and fewer peer relations.
We investigated 429 consecutive patients, aged 5 to 18 (mean: 11.0 +/- 3.1) years, diagnosed with migraine or tension-type headache. The patients underwent either MRI or exclusively clinical follow-up examinations. Magnetic resonance imaging revealed normal findings in 82.3% and structural changes in 17.7%. However, the vast majority of these changes had minimal or no pathological relevance, and a causal relationship to the patient's headache could not be proven in any case. In the non-MRI group, clinical follow-up examinations confirmed the initial diagnosis in all patients and MRI was not required in any of these subjects. In conclusion, our study shows a poor relation between recurrent headache fulfilling the criteria of migraine and tension-type headache and structural changes incidentally detected by MRI. In addition, it suggests that clinical follow-up examinations are reliable. Accordingly, MRI is not required for routine examination of recurrent headache in children and adolescents, but it should be performed in patients with abnormal neurological findings, atypical headache pattern, or significant change of preexisting headache.
The aim of this study was to investigate whether the IHS criteria for migraine and tension-type headache depend on gender. Among 409 children and adolescents with recurrent idiopathic headache seen at a university outpatient clinic, girls had significantly more often migraine with aura. Also, there was a trend towards a higher frequency of tension-type headache in girls. In migraine, aggravation of headache by physical activity and occurrence of aura symptoms were more common in females, whereas vomiting and phonophobia occurred more often in males. In tension-type headache, females more often reported mild intensity of headache. All other criteria were similar in both sexes. Age influenced the expression of some of the accompanying symptoms in the various types of migraine, but had only minimal influence on other diagnostic criteria of migraine and tension-type headache in females as well as in males. Our study suggests that the frequency of migraine (except that of migraine with aura) is similar among girls and boys, that tension-type headache may occur more often in girls, and that gender has some influence on the IHS criteria for migraine, but almost no influence on those of tension-type headache.
