Treatment of PTSD and Chronic Daily Headache.

Posttraumatic stress disorder (PTSD) is often comorbid with chronic migraine (CM) and chronic tension-type headache (CTTH). Trauma-focused cognitive behavioral psychotherapies, selective serotonin reuptake inhibitors (SSRIs), and venlafaxine have demonstrated efficacy in the treatment of PTSD. Amitriptyline, topiramate, sodium valproate, and botulinum toxin A are efficacious for treatment of chronic daily headache (CDH). Treatment studies on individuals with CDH and comorbid PTSD, however, are limited. As such, multiple therapeutic agents or modes of interventions typically are necessary, such that comprehensive treatment simultaneously utilizes approaches with established efficacy for each individual condition.
