Abstract

BACKGROUND: Headache is often comorbid with post-traumatic stress disorder yet overlooked in health assessments of refugees.

OBJECTIVES: To describe prevalence of severe headache among refugees with post-traumatic stress disorder and compare severity of post-traumatic stress disorder symptoms and treatment outcomes among those with and without severe headache.

METHODS: This follow-up study used data from the Danish Database on Refugees with Trauma. Participants were recruited from 2009 to 2015 at a specialized psychiatric clinic. Prevalence of severe headache was computed by age, sex, and history of head injury or torture. Severe headache was defined as maximum headache scores on the Hopkins Symptom Checklist, Symptom Checklist-90 or the Visual Analogue Scale. Groups with and without severe headache were described according to validated questionnaires before and after 12-18 months of multidisciplinary treatment for post-traumatic stress disorder. Regression analyses were used to analyze associations between headache at start of treatment and symptom burden post-treatment, controlled for pre-treatment scores and possible confounders.

RESULTS: Among 403 female and 489 male participants, nearly all (97.5%) complained of headaches. Severe headache prevalence was 31.4% to 50.0% (depending on which questionnaire was used) and was significantly more common among females and those aged 30-49 years. There was no clear relationship between headache and head injury or torture. Participants with severe headache had heavier symptom burdens compared to those without severe headache. Post-treatment, headache prevalence by age and sex did not change significantly. Those without severe headache showed a tendency toward improvement in outcome measures; this was not seen among those with severe headache. Pre-treatment headache scores were correlated with all outcome measures. Regression analyses controlled for pre-treatment scores of the outcome variables showed associations between pre-treatment headache scores (Hopkins Symptom Checklist or Symptom Checklist-90) and post-treatment scores for intrusion, numbing, hyperarousal, anxiety, disability, and quality of life (all p < 0.02).

CONCLUSION: Headache is a prevalent comorbid condition among refugees with post-traumatic stress disorder. Measures of pre-treatment headache severity appear to predict post-traumatic stress disorder treatment outcomes. Severe headache adversely affects post-traumatic stress disorder prognosis. Assessment and treatment options should be studied further.
