Objective: Demonstrate differences in symptom patterns among Veterans with posttraumatic headache who sustained head injury through mechanical injury and blast exposure.
Design : Three-arm RCT
Setting: VA Polytrauma Rehabilitation Center in South Texas Veterans Health Care System
Participants: 240 Veterans with persistent posttraumatic headaches and comorbid posttraumatic stress disorder who participated in a large, VA/DoD funded, prospective randomized clinical trial of non-pharmacological interventions for posttraumatic headache.
Interventions: This study used a three-arm randomized clinical trial format for which participants were randomly assigned into one of three intervention arms as follows: 1. Eight-session manualized nonpharmacological intervention for headache 2. Twelve-session manualized nonpharmacological intervention for PTSD 3. Usual Care in VA Polytrauma Clinic
Main Outcome Measures: Headache Impact Score-6 (six-item self-report measure of headache-related disability); Structured Diagnostic Interview for Headache (clinician-guided interview describing headache symptoms/phenotype); Headache Diary (frequency, duration, severity); NIH Toolbox Cognitive Assessment (memory, concentration, attention)
Results: Baseline assessment data from a large, federally-funded clinical trial shows differences in the manifestation of headache after head injuries of different mechanisms (e.g., more severe and disabling headache in blast exposed compared to mechanical injury).
Conclusions: Veterans with blast exposure experience posttraumatic headache that is phenotypically distinct from those with mechanical injury to the head or neck (e.g., fall, blunt trauma to the head). These findings suggest differential treatment response between these two groups that may indicate the need for tailored treatments targeting posttraumatic headache of different origins.
