Cluster headache in children and adolescents: a systematic review of case reports

Abstract

To describe the clinical characteristics and therapeutic options available to paediatric patients with cluster headache. Based on a literature search of the medical databases PubMed, LILACS, and Web of Science and using selected descriptors, we carried out a systematic review of case reports on cluster headache in paediatric patients published from 1990 to 2020. Fifty-one patients (29 males, 22 females) with a mean (SD) age of 9 years 7 months (3y 10mo; range 2-16y) were diagnosed with cluster headache. The mean (SD) diagnosis was made 27.8 months (26.2mo) after the onset of cluster headache. Pain occurred at night or on waking up (76.5%) and consisted of 1 to 3 attacks per day (62.7%) lasting 30 to 120 minutes (68.6%). Headaches were unilateral (90.2%), had a pulsatile character (64.7%), and severe intensity (100%). There were autonomic manifestations (90.2%) predominantly ipsilateral to pain, in this order: lacrimation; conjunctival injection; nasal congestion; ptosis; eyelid oedema; and rhinorrhoea. Sumatriptan and oxygen inhalation were the most effective treatments for acute manifestation. Prophylaxis, corticosteroids, verapamil, and gabapentin were the most effective drugs. Due to the small number of published studies, this review could not provide reliable data; however, it appears that cluster headache in children and adolescents is similar to adults, both in clinical characteristics and treatment.
