Diagnostic criteria for migraine and psychogenic headache in children

The headache histories obtained from 214 children were analysed by computer to see whether it was possible to identify and classify migraine, and to distinguish children with psychogenic headache. During headache attacks, most children had no or very few associated symptoms. For classification, 175 patients were divided into four homogeneous groups; the remaining 39 could not be grouped. An overlap between the different groups was found. Psychogenic headache emerged as a clearly definable syndrome, characterised by psychological problems and daily headache for a period of at least one month (10 patients). When the 214 patients were grouped according to the classification of the Headache Classification Committee of the International Headache Society, distinguishing those children with psychogenic headache was no longer possible
