Retrospective Observational Study Amidst Myriad Conundrums and Myths of Pediatric Headaches: A Critique on Diagnostics and Effectiveness of Interventions.

Abstract

Objective To study the etiological profile of pediatric headaches (PH) in a tertiary child neurology clinic and to determine the utility of diagnostics, interventions, and long-term prognosis. Methods Children (ages 4-15) observed over four years were recruited retrospectively. In primary headaches, the headache frequency and impact on quality of life (QOL) parameters at pre-treatment (T1) were compared post-treatment at follow-up (T2). Results Of the 311 eligible patients, 285 had primary headaches (Tension-Type Headache {TTH}: 156; Migraine: 129), and 26 had secondary headaches. The mean (±SD) onset age was 10 (±3) years with a male-to-female ratio of 2.3:1. Migraine was more common in children aged less than seven years (17/28) and TTH in older patients (146/283). The most common causes of secondary headache were intracranial hypertension (ICH) in 11/26 patients (fouridiopathic intracranial hypertension (IIH), four following aseptic meningitis, three with cortical vein thrombosis), and ophthalmologic causes in 7/26 (of these five had convergence insufficiency). Hypertension was a rare cause of secondary headaches (2/26 patients). Neuroimaging was performed in 173/311 (56%), primarily for parental anxiety (160/173; 92%), and was abnormal in only four. At T2 (Median time to follow-up: 29 months; Interquartile range: 22-37 months), data were collected in 207/285 patients with primary headaches (TTH: 109; Migraine: 98). In both migraine and TTH groups, there were statistically significant reductions (p-value <0.0001) in headache frequency and QOL parameters. Conclusion In our study, TTH wasthe most common cause of PH. Neuroimaging was normal in most cases. Psychological interventions were effective but underutilized. The symptoms of primary headaches improved significantly over time, despite poor adherence to prophylactic medications.
