title: Clinical categorization of 312 children with chronic headache.
abstract: Three hundred and twelve children referred to an outpatient pediatric neurology clinic, with headache that lasted more than 3 months, were retrospectively reviewed. On average, the age of pain onset was 8.4 years. Migraine was diagnosed in 54% of these children and tension-type headache was found in 22% of those with chronic headache. Most children (85%) had common migraine, while classic and complicated migraine was found in only 8.8% and 5.3%, respectively. Brief headaches, lasting from seconds to a few minutes, were found in 5.1% of the children evaluated. In this subgroup, a high rate of epileptic EEG activity was found. Out of 110 children who had undergone computerized tomography, only one was pathological (posterior arachnoid cyst). Our results indicate that chronic and recurrent headache without accompanying neurological symptoms are usually benign and therefore in most cases neuroimaging is not indicated.
