Advancements in pediatric headache.

Purpose of review: To provide an update on advancements in pediatric headache.

Recent findings: The symptomatology associated with primary headache disorders has been compared with ICHD-3 criteria. Primary stabbing headache pain lasts longer than 3 seconds in over half of patients. Persistent posttraumatic headache or new daily persistent headache have significant overlap in pain character and nonpain-related symptoms with migraine. In a large cohort with continuous headache at first follow-up, 47% reported resolution of their continuous headache and 19.4% had a 50% or greater reduction in frequency with improvements in fluid intake, sleep, not skipping meals, and exercise. There was no correlation with improved lifestyle habits and clinical outcomes despite the overall improvement. Studies noted significant improvement in headache scores with onabotulinum toxin A and incobotulinum toxin A injections with limited side effects. Intranasal sumatriptan without concurrent intravenous therapies found a clinically meaningful decrease in pain score prior to discharge with shorter lengths of stay and lower emergency department costs compared with the those who received intravenous therapies.

Summary: Newer studies have suggested changes to symptomatology and duration of pediatric headache syndromes. Onabotulinum toxin A and incobotulinum toxin A injections, and emergency department intranasal sumatriptan are well tolerated therapies in pediatric headache.
