Headache comorbidity in refugees and migrants with post-traumatic stress disorder.

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.

Poor social support and loneliness in chronic headache: Prevalence and effect modifiers.

Objective: To explore the prevalence of poor social support and loneliness among people with chronic headache, and how these might be effect modifiers in the relationships between chronic headache and stress, medication overuse, and self-rated health.

Background: Poor social support and loneliness are consistently linked to worse health outcomes. There are few epidemiologic studies on their effect on headache.

Comparison of 3 Treatment Strategies for Medication Overuse Headache: A Randomized Clinical Trial.

Importance: Medication overuse headache (MOH) is a disabling, globally prevalent disorder representing a well-known and debated clinical problem. Evidence for the most effective treatment strategy is needed.

Objective: To compare 3 treatment strategies for MOH.

Monitoring chronic headache and medication-overuse headache prevalence in Denmark.

Objectives: To study chronic headache and medication-overuse headache (MOH) prevalence; to identify groups with high prevalence of these conditions; and to identify the most frequently used pain medications among respondents with chronic headache.

Background: Chronic headache and MOH prevalence in Denmark were last estimated in 2010.

Methods: In this cross-sectional study, 104,950 individuals aged ≥16 years were randomly sampled for the 2017 Danish Capital Region Health Survey.

Economic benefits of treating medication-overuse headache - results from the multicenter COMOESTAS project.

Background: Medication-overuse headache is a costly disease for individuals and society.

Objective: To estimate the impact of medication-overuse headache treatment on direct and indirect headache-related health care costs.

Methods: This prospective longitudinal study was part of the COMOESTAS project (COntinuous MOnitoring of Medication Overuse Headache in Europe and Latin America: development and STAndardization of an Alert and decision support System).

The DoloTest® in a specialized headache center among patients receiving psychological treatment. A pilot study.

Background The DoloTest is a newer health-related quality of life (HRQoL) monitoring instrument for pain, not yet validated for headache. Aims To examine the usefulness of the DoloTest in a specialized headache center. Methods The sample consisted of patients referred to psychologists from the Danish Headache Center (DHC) for whom the test was carried out at start of, end of, and 6 months after treatment.

National awareness campaign to prevent medication-overuse headache in Denmark.

Background Medication-overuse headache is prevalent, but in principle preventable. Objective To describe the Danish national awareness campaign for medication-overuse headache. Methods The Danish Headache Center, the Association of Danish Pharmacies, and headache patient organizations implemented a four-month medication-overuse headache awareness campaign in 2016.

Level of physical activity, well-being, stress and self-rated health in persons with migraine and co-existing tension-type headache and neck pain.

Background: The prevalence of migraine with co-existing tension-type headache and neck pain is high in the general population. However, there is very little literature on the characteristics of these combined conditions. The aim of this study was to investigate a) the prevalence of migraine with co-existing tension-type headache and neck pain in a clinic-based sample, b) the level of physical activity, psychological well-being, perceived stress and self-rated health in persons with migraine and co-existing tension-type headache and neck pain compared to healthy controls, c) the perceived ability of persons with migraine and co-existing tension-type headache and neck pain to perform physical activity, and d) which among the three conditions (migraine, tension-type headache or neck pain) is rated as the most burdensome condition.

[Clinical presentation and treatment of medication-overuse headache].

Medication-overuse headache (MOH) is a disabling, costly and often overlooked disorder. The prevalence in Denmark is 1.8% equivalent to 80.

Medication-overuse headache: a perspective review.

Medication-overuse headache (MOH) is a debilitating condition in which frequent and prolonged use of medication for the acute treatment of pain results in the worsening of the headache. The purpose of this paper is to review the most recent literature on MOH and discuss future avenues for research. MOH accounts for a substantial share of the global burden of disease.

Prescription pain medications and chronic headache in Denmark: implications for preventing medication overuse.

Purpose: The aim of the present paper is to study which prescription pain medications are most commonly dispensed to people with chronic headache (CH), particularly those with medication-overuse headache (MOH).

Methods: This cross-sectional study analysed prescription pain medications dispensed within 1 year to 68,518 respondents of a national health survey. Participants with headache ≥ 15 days per month for 3 months were classified as having CH.

Medication overuse, healthy lifestyle behaviour and stress in chronic headache: Results from a population-based representative survey.

Aim: This cross-sectional study investigated associations between chronic headache (CH) with and without medication overuse, healthy lifestyle behaviour, and stress.

Methods: Questionnaires were sent to 129,150 adults. Those with headache ≥15 days per month for three months were classified as having CH then further described as having medication-overuse headache (MOH) or CH without medication overuse.

The association between candidate migraine susceptibility loci and severe migraine phenotype in a clinical sample.

Introduction: The objective of the study was to follow up and to test whether 12 previously identified migraine-associated single nucleotide polymorphisms were associated as risk factors and/or modifying factors for severe migraine traits in a Danish clinic-based population.

Methods: Semi-structured migraine interviews, blood sampling and genotyping were performed on 1806 unrelated migraineurs recruited from the Danish Headache Center. Genotyping was also performed on a control group of 6415 people with no history of migraine.

Epidemiology of concurrent headache and sleep problems in Denmark.

Aims: There are no previous epidemiologic studies on concurrent headache and sleep problems (HSP). This cross-sectional study aimed to determine the prevalence of HSP in Denmark, broadly characterize those with HSP, and examine associations between HSP and socioeconomic/lifestyle factors.

Methods: A total of 129,150 randomly selected individuals were invited to participate in the Danish National Health Survey 2010.

Prevalence of chronic headache with and without medication overuse: associations with socioeconomic position and physical and mental health status.

Near-daily intake of acute symptomatic medication for frequent headache increases the risk for medication-overuse headache (MOH). Chronic headache (CH) and MOH prevalences are inversely related to socioeconomic position (SEP). It is not known how SEP influences the health status of people with these headaches.
