Chronic daily headache (CDH) occurs in 1-2% of children and adolescents. It can evolve from either episodic tension-type headache or episodic migraine, or can appear with no previous headache history. As with other primary headache disorders, treatment is based on the level of disability. There are children and adolescents who cope well, but there are others who are markedly disabled by their chronic headaches. As in adults, children and adolescents with CDH are at risk for medication overuse. CDH is a diagnosis of exclusion, based on a thorough history, normal physical examination, and negative neuroimaging findings. Along with the chronic headaches, children with this condition may have co-morbid sleep problems, autonomic dysfunction, anxiety, and/or depression. Principles of treatment include identifying migrainous components, stopping medication overuse, stressing normalcy, using rational pharmacotherapy, and addressing co-morbid conditions. Successful outcomes often involve identifying an appropriate headache preventative, reintegration into school, and family participation in resetting realistic expectations.
