The optimal length of headache recording in juvenile migraine patients

The representativeness of headache recording periods of one, two, three, four and five weeks for juvenile migraine was examined in 41 juvenile patients (suffering from migraine attacks at least twice a month). At pre-treatment and at follow-up, on average a three-week recording period was found to be adequate. On the basis of these findings a longer data-collection period is recommended for juvenile migraineurs than for adult migraine patients at follow-up.
