Headaches are common in childhood. Recently, there has been an increasing trend toward pharmacological treatment.Secondary causes were excluded first in patients who attended our clinic with headache. Those without a secondary cause were evaluated as primary headache and classified into subgroups. Behavior-modifying recommendations (adequate and regular sleep, adequate and regular nutrition, adequate fluid intake, and restriction of screen exposure) were given to all patients. Patients were re-evaluated at 1, 3, and 6 months. Pharmacologic treatment was started at the end of the 1st month with follow-up at the 3rd and 6th months for those who did not benefit from the behavior-modifying recommendations.A total of 875 patients presented with headache complaints, of which 30.6% were evaluated as primary headache. Behavior-modifying recommendations were beneficial for 23.1% with migraine with aura; 20.3% with migraine without aura, and 36.8% with tension-type headache.Secondary causes should be excluded first in patients who present to the pediatric neurology clinic with headache. For patients diagnosed with primary headache, behavioral modifications to change the lifestyle should be tried before giving pharmacologic treatment.
