OBJECTIVE: To examine headache trajectories among persons with mild traumatic
brain injury (MTBI) in the year after injury and the relation of headache
trajectory to posttraumatic stress disorder (PTSD) at 1 year postinjury. DESIGN:
Prospective, longitudinal study. SETTING: Participants were recruited through a
university medical center and participated in follow-up assessments by telephone.
PARTICIPANTS: Prospectively enrolled individuals (N=212) within 1 week of MTBI
who were hospitalized for observation or other system injuries. Participants were
assessed at baseline and 3, 6, and 12 months postinjury. INTERVENTIONS: Not
applicable. MAIN OUTCOME MEASURES: Participants rated average headache pain
intensity using the 0 to 10 numerical rating scale at each assessment period.
The PTSD Checklist-Civilian Version was completed at 12 months postinjury. RESULTS:
Latent class growth analysis produced a 4-trajectory group model, with groups
labeled resolved, worsening, improving, and chronic. Multivariate regression
modeling revealed that younger age and premorbid headache correlated with
membership in the worse trajectory groups (worsening and chronic; P<.001).
Univariate regression revealed a significant association between PTSD and
membership in the worse trajectory groups (P<.001). CONCLUSIONS: Headache is
common in the year after MTBI, with younger people, persons who previously had
headaches, and persons with PTSD more likely to report chronic or worsening
headache. Further research is needed to examine whether PTSD symptoms exacerbate
headaches or whether problematic headache symptoms exacerbate PTSD.
