Fourteen percent of participants reported pre-existing migraine before head injury, and there was no difference in the proportion of veterans with pre-existing migraine based on headache onset. Headache onset times were not associated with sex, headache phenotype, or mechanism of injury. There were no significant differences in proportion of veterans with headache onset within 7 days of head injury based on headache phenotype (70% migraine onset within 7 days, 70% tension-type headache within 7 days, 56% cluster headache within 7 days; p \u2265 .364). Similar findings were observed for head injury (64% blast, 60% blunt; p\u2009=\u2009.973). There were no significant differences observed between headache onset groups for psychiatric symptoms (Posttraumatic Stress Disorder Checklist for DSM-5\u2009=\u20091.3, 95% CI\u2009=\u2009\u221227.5, 30.1; Patient Health Questionnaire-9 Item\u2009=\u20093.5, 95% CI\u2009=\u2009\u22126.3, 3.7; Generalized Anxiety Disorder Screener\u2009=\u20096.5, 95% CI\u2009=\u2009\u22122.7, 15.6).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Although most of the sample reported headache onset within 7 days of head injury, one-third experienced an onset outside of the diagnostic range.
