Headache disorders subsumed under the term chronic daily headache (CDH), including chronic migraine, chronic tension-type headache and new daily persistent headache, affect up to 4% of the pediatric population and can be highly disabling and challenging to effectively treat. Although historically the knowledge base about this group of headache disorders in children primarily was derived from clinical observation and extrapolation from adult studies, over the past several years there have been important research findings relevant to the development and management of pediatric CDH that can help inform clinical practice. The intent of this paper is to provide a focused review on recent empirical work done on pediatric CDH and suggest avenues for future work.
