Chronic Daily Headache in U.S. Soldiers After Concussion

Objective.— To determine the prevalence and characteristics of, and factors associated with, chronic daily headache (CDH) in U.S. soldiers after a deployment-related concussion.

Methods.— A cross-sectional, questionnaire-based study was conducted with a cohort of 978 U.S. soldiers who screened positive for a deployment-related concussion upon returning from Iraq or Afghanistan. All soldiers underwent a clinical evaluation at the Madigan Traumatic Brain Injury Program that included a history, physical examination, 13-item self-administered headache questionnaire, and a battery of cognitive and psychological assessments. Soldiers with CDH, defined as headaches occurring on 15 or more days per month for the previous 3 months, were compared to soldiers with episodic headaches occurring less than 15 days per month.
